Indicators and Reconfigurable Telltales (RTTs)

NOTE: It is important to view each of the cluster options in the Overview to identify which IPC uses specific fixed location indicators.

Refer to: Instrument Panel Cluster (IPC) - Overview .

Prove-Out

The IPC carries out a display prove-out to verify the gauges function and all module controlled warning indicator lamps and monitored systems are functioning correctly within the IPC. Upon initiation of the prove-out, the gauges sweep from one stop to the other then return to the normal indication state based on the input received. The IPC also provides a timed prove-out of some indicators while other indicators illuminate upon engine start up or have no prove-out.

ABS Warning

If a fault condition exists in the ABS, the ABS module sends the ABS warning indicator request message to either flash or illuminate the ABS indicator or RTT warning indicator.

Refer to ABS/Brake/Stability-Traction Control System Indication description below, for information on the conditions when the ABS warning indicator is turned on.

ABS/Brake/Stability-Traction Control System Indication

The brake/stability-traction control system indication is controlled almost entirely by the ABS module. The ABS module can illuminate multiple indicators for various fault conditions. The following table provides a summary of the basic fault conditions and the indicators that are illuminated for each condition.

NOTE: Refer to the Normal Operation and Fault Condition description before each brake/stability-traction control system indicator Pinpoint Test for the IPC default action for network/missing message conditions.

Adaptive Cruise Control/Cruise Control

The IPC provides a cruise control RTT indicator when the cruise control or adaptive cruise control system is active or in standby mode.

Airbag Warning

The IPC provides the airbag warning RTT indicator if a SRS concern is detected. If a fault is detected in the airbag circuit, the RCM sets a DTC and the IPC illuminates the airbag warning RTT indicator.

Auto High Beam/Adaptive High Beam

The IPC provides the auto high beam or adaptive high beam RTT indicator to indicate the auto high beam or adaptive high beam is active.

Auto Hold

The IPC provides the auto hold RTT indicator to indicate the state of the auto hold feature. The auto hold feature holds a vehicle stationary once it has come to a stop using the brakes, allowing the driver to remove his or her foot from the brake pedal.

Auto Stop-Start

The IPC provides the auto stop-start RTT indicator, along with multiple messages displayed throughout the auto stop-start system operation, to inform the driver of the system status and to provide direction when driver intervention is required.

The auto stop-start indicator informs the driver of the following states:

Indicator State	System Status
Solid green	The auto stop-start feature has temporarily turned off the engine.
Solid amber	A stop-start system concern exists.
Flash in either green or amber	A system state as determined by the PCM.

Auto Tow Haul

NOTE: Total combined vehicle mass data threshold is programmed at approximately 10, 500 lbs (vehicle and trailer). If the total mass is below the 10, 500 lb threshold, the transmission maintains the base shift points and the tow haul indicator remains off. Example: if the vehicle weight is 6, 000 lbs and the trailer weight is below 4, 500 lbs, the tow haul does not illuminate and the transmission shifts at the base shift points (no tow haul assist).

The tow haul RTT indicator illuminates when the tow haul system has been engaged and is actively providing tow haul control for the vehicle. There are two tow haul systems: with trailer tow and without trailer tow. The message center provides a menu on both systems allowing the driver to select OFF or AUTO. Both systems must determine there is a trailer connected using a programmed vehicle mass data threshold before the system engages and requests the IPC turn on the tow haul RTT indicator.

On vehicles equipped with trailer tow with AUTO selected, once the system determines a vehicle mass (trailer connected), the IPC illuminates the tow haul RTT indicator. If the driver stops and turns off the ignition (potential refueling or other event where the trailer remains connected), then turns on the ignition again the tow haul RTT indicator remains on and the system continues to provide tow haul control once it determines vehicle mass still meets criteria. If vehicle mass remains unchanged, the indicator remains on. If a change in vehicle mass is detected (trailer disconnected or a lighter trailer that doesn't meet mass criteria), the system no longer provides tow haul control and the IPC turns off the tow haul RTT indicator.

On vehicles without trailer tow with AUTO selected, the tow haul system does not re-start in tow haul mode after an ignition cycle. The customer needs to drive enough for the tow haul system to relearn vehicle mass above the programmed threshold which can take several acceleration events to learn. Once the system determines the trailer is connected, the IPC turns on the tow haul RTT indicator.

When the driver enters the message center tow haul menu and changes the selection, the IPC sends the auto tow allow request menu message to the PCM. Once the PCM acts upon the request to change state, the PCM sends the auto tow allow status menu message to the IPC.

When the system is actively providing tow haul control, the PCM sends the auto tow active status message to the IPC to illuminate the auto tow haul RTT indicator.

Blind Spot Monitoring System (BLIS®) Off

The IPC provides a BLIS off RTT indicator to inform the driver the BLIS is turned off.

Brake Warning

The brake warning RTT indicator informs the driver the brake fluid level is low, there is a failure in the base brake system or the parking brake is applied. The IPC uses messaged inputs to control the brake warning RTT indicator.

Refer to ABS/Brake/Stability-Traction Control System Indication description above, for information on the conditions when the brake warning RTT indicator is turned on.

Charge Warning (12-Volt Battery)

The IPC provides a charging system RTT indicator along with message displays indicating the charging system status. When a fault is present in the charging system, the BCM sends the battery low state of charge message to the IPC to display message center warning messages and the charging system RTT indicator.

Door Ajar, Hood Ajar Or Liftgate Ajar Warning

The IPC provides a door ajar warning RTT indicator along with message displays to indicate the status of the doors, hood and liftgate. The BCM monitors each of the ajar inputs and sends the specific door ajar status message to the IPC to display the ajar warning RTT indicator and corresponding warning message.

Distance Indication

The IPC provides a distance indication RTT indicator when the Calm screen feature is selected, and other indication displays are not visible. The distance indication RTT indicator informs the driver that the vehicle is approaching a vehicle in front and the system determined the distance between vehicles is too close.

ELD Indicator

The ELD indicator informs the driver the locking differential is engaged.

Electric Park Brake

The electric park brake RTT indicator illuminates when a fault in the electric park brake system is detected.

Engine Over-Temperature

The IPC provides a RTT warning indicator to alert the driver the engine is over temperature.

Fog Lamp - Front

The IPC provides a front fog lamp RTT indicator to indicate when the front fog lamps are on.

Fog Lamp - Rear (China Only)

The IPC provides a rear fog lamp RTT indicator to indicate when the rear fog lamps are on.

Forward Collision System

The IPC provides a RTT warning indicator to alert the driver the forward collision warning system is unavailable or a fault is detected, disabling the system.

Four Wheel Drive System

The IPC provides a RTT indicator for each 4WD position selected: 2H, 4H, 4L, 4A.

High Beam

The high beam RTT indicator informs the driver the high beams are on.

Hill Descent Control

The IPC provides a hill descent control RTT indicator to indicate when the HDC is in ready mode, active control mode, or in an over-temperature mode with the system cooling.

Lane Centering Aid

The IPC provides the lane centering aid on RTT indicator to indicate the lane centering aid has been turned on, is active or in standby mode. The RTT indicator changes colors to indicate system status.

Lane Keeping System

The IPC provides the lane keeping system on RTT indicator to indicate the lane keeping system has been turned on, is active or in standby mode. The RTT indicator changes colors to indicate system status.

LED Low Beam Malfunction

The IPC provides the LED low beam malfunction RTT indicator to indicate a fault in the LED lighting system.

Lights On

When the parking lamps are turned on, the BCM sends the park lamp status to the IPC to illuminate the lights on RTT indicator.

Low Engine Oil Pressure

The IPC uses the engine oil pressure warning indicator request and engine RPM data from the PCM to control the low engine oil pressure RTT indicator. The engine oil pressure sensor is hardwired to the PCM. The IPC requires engine RPM above 400 RPM before the message center displays the low engine oil pressure warning.

Low Fuel

To supplement the fuel gauge indication, the IPC provides the low fuel warning RTT indicator.

The IPC uses the low fuel warning indicator request message sent from the PCM to the IPC to control the low fuel warning RTT indicator.

When the DTE is 120 km (75 miles) (for MyKey®) and 80 km (50 miles), 40 km (25 miles), 20 km (10 miles) and 0 km (0 miles) for all keys, the low fuel RTT indicator illuminates.

Low Washer Fluid Level

The low washer fluid level switch is hardwired to the IPC through a single signal circuit and is grounded through a separate ground circuit. The IPC provides a reference voltage to the washer fluid level switch. When the washer fluid is low, the washer fluid level switch closes, pulling the reference voltage low, and the IPC illuminates the low washer fluid level RTT indicator.

MIL (Check Engine)

The IPC provides the MIL or check engine lamp RTT indicator when a fault in the engine or the powertrain system is detected.

Overspeed Warning (Gulf Cooperative Countries [GCC])

The IPC provides an overspeed warning RTT indicator when the vehicle speed has reached or exceeded the 120 km/h (75 mph) threshold.

Powertrain Malfunction (Wrench) Warning

The IPC provides a powertrain malfunction (wrench) RTT warning indicator to indicate a:

BCM concern.
4WD system concern.
gearshift concern.
powertrain concern (Electronic Throttle Control [ETC]).
transmission concern.

Progressive Range Select

The IPC provides the progressive range select RTT indicator to display each selected transmission gear position.

Seatbelts/Belt-Minder

The RCM monitors the driver and front passenger seatbelt positions through the seatbelt buckle switch. The RCM provides the driver and passenger seatbelt buckle status to the IPC to turn on or turn off the seatbelt warning RTT indicator.

Speed Sign Recognition

The speed sign RTT indicates the speed limit recognized by the system as the current posted speed limit based on the last posted speed sign recognized. The IPC uses speed sign recognition data provided by the IPMA.

Stability-Traction Control (Sliding Car Icon)

The stability-traction control (sliding car icon) RTT indicator informs the driver of the current status of the stability and traction control systems. The stability-traction control indicator illuminates when a fault condition exists or when an active traction control or stability control event is occurring.

Refer to ABS/Brake/Stability-Traction Control System Indication description above, for information on the conditions when the stability-traction control indicator (sliding car icon) is turned on.

Traction Control Disabled (Sliding Car OFF Icon)

The stability-traction control is configured on/off from the console mounted switch. When the driver enables or disables the stability-traction control system, or when a system fault disables the stability traction control, the ABS module sends the traction control off indicator request message to the IPC to illuminate or turn off the stability-traction control disabled (sliding car OFF icon) RTT indicator based upon the system state.

Refer to ABS/Brake/Stability-Traction Control System Indication description above, for information on the conditions when the stability-traction control disabled indicator (sliding car OFF icon) is turned on.

When a MyKey® administrator has set the AdvanceTrac® feature to always on and a MyKey® programmed key is in use, the stability-traction control system cannot be disabled. The menu selection in the message center used to disable the stability-traction control system does not display when a MyKey® is in use, but remains active for the MyKey® administrator to select the AdvanceTrac® always on feature off. The stability-traction control indicator still functions normally to indicate a stability-traction control system fault and a stability-traction control active event.

TPMS Warning

If the BCM determines the tire pressure has exceeded the low tire pressure limits, the tire pressure warning indicator request message is sent to the IPC to illuminate the TPMS warning RTT indicator.

If a TPMS monitor or sensor fault condition exists, the BCM sends the tire pressure warning indicator request message to the IPC to flash the TPMS RTT warning indicator. The IPC flashes the TPMS RTT warning indicator for 75 seconds then turns the indicator on solid.

Turn Signal/Hazard

When the multifunction switch is in the LH or RH turn position or if the hazard switch is on, the BCM sends the left or right turn lamp on request to the IPC to flash the turn signal RTT indicator on and off.
