System Operation: Indicators

WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

ABS Warning Indicator

The IPC receives the ABS warning indicator request message from the GWM over the HS-CAN3. The GWM receives the ABS warning indicator request message from the ABS module over the HS-CAN2. 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 warning indicator.

Refer to ABS/Brake/Stability-Traction Control System Indication description 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 (PPT) for the IPC default action for network/missing message conditions.

Airbag Warning Indicator

The IPC receives the airbag warning indicator request from the GWM over the HS-CAN3. The GWM receives the airbag indicator request from the RCM over the HS-CAN2. If a SRS concern is detected, the RCM sets a DTC and the IPC illuminates the airbag warning indicator.

Auto Stop/Start Indicator

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

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 - system state as determined by the PCM.

The IPC receives the stop/start standby request from the GWM over the HS-CAN3. The GWM receives the auto stop/start standby request from the PCM over the HS-CAN1.

Brake Warning Indicator

The brake warning indicator informs the driver the brake fluid level is low, there is a failure in the base brake system or the electronic park brake is applied. The IPC uses 3 messaged inputs to control the brake warning indicator.

Brake (red) warning indicator request
Brake fluid level low message request
Parking brake (red) indicator request

The IPC receives the brake (red) warning indicator request, the brake fluid level low message request and the parking brake (red) indicator request messages from the GWM over the HS-CAN3.

The GWM receives the brake (red) warning indicator request and the parking brake (red) indicator request from the ABS module over the HS-CAN2.

The GWM receives the brake fluid level low message request from the BCM over the HS-CAN2.

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

Electronic Park Brake Indicator

The electronic park brake indicator indicates a fault in the electronic park brake system. The IPC receives the parking brake (yellow) indicator request from the GWM over the HS-CAN3. The GWM receives the parking brake (yellow) indicator request from the ABS module over the HS-CAN2.

High Beam Indicator

The high beam indicator informs the driver that the high beams are on. The IPC receives the high beam status message from the GWM over the HS-CAN3. The GWM receives the high beam status message from the BCM module over the HS-CAN1.

LH/ RH Turn Signal/Hazard Indicator

When the multifunction switch is in the LH or RH turn position or if the hazard switch is on, the BCM sends the turn indication request to the GWM over the HS-CAN1. The GWM sends the turn indication request to the IPC over the HS-CAN3. Upon receipt of the applicable turn signal on/off message, the IPC flashes the turn signal indicator on and off.

Lights On Indicator

When the parking lamps are turned on, the BCM sends the parklamp status message to the GWM over the HS-CAN1. The IPC receives the parklamp status message from the GWM over the HS-CAN3 to illuminate the lights on indicator.

MIL

The IPC receives the MIL request from the GWM over the HS-CAN3. The GWM receives the MIL request from the PCM over the HS-CAN1.

PRNDL Indicator

The IPC uses the following messages to control the PRNDL:

Battery shed level request
Ignition status
Transmission gear display
Transmission shift mode display
Transport mode
Vehicle speed

The IPC receives all messaged inputs from the GWM over the HS-CAN3.

The GWM receives the transmission gear display, transmission shift mode display and vehicle speed messages from the PCM over the HS-CAN1.

The GWM receives the ignition status, transport mode and battery shed level request messages from the BCM over the HS-CAN1.

When the vehicle is in transport mode or during battery load shed operation, the PRNDL is not displayed upon entry or exit from the vehicle to prevent battery drain during longer periods of time when the vehicle is not in use, such as those experienced during vehicle transport.

The IPC also uses a park position detect switch (part of the selector lever) input to signal the IPC the shift lever is fully seated in the PARK (P) position. The IPC compares the park position detect switch input with the transmission gear display message sent from the PCM.

Safety Belt Warning Indicator

The RCM monitors the driver safety belt position through the driver safety belt buckle switch. The RCM provides the driver safety belt buckle status message to the GWM over the HS-CAN2. The GWM provides the driver safety belt status message to the IPC over the HS-CAN3 to either turn on or turn off the safety belt warning indicator.

Stability-Traction Control Indicator (Sliding Car Icon)

The stability-traction control indicator (sliding car icon) 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. The IPC receives the stability-traction control indicator request message from the GWM over the HS-CAN3. The GWM receives the stability-traction control indicator request message from the ABS over the HS-CAN2.

Refer to ABS/Brake/Stability-Traction Control System Indication description for information on the conditions when the stability-traction control indicator (sliding car icon) is turned on. Refer to: Anti-Lock Brake System (ABS) And Stability Control - System Operation And Component Description .

Stability-Traction Control Disabled Indicator (Sliding Car OFF Icon)

The stability-traction control is configured on/off through the message center. When the driver enables or disables the stability-traction control system, the ABS module sends the traction control mode message to the GWM over the HS-CAN2. The GWM sends the traction control mode message to the IPC over the HS-CAN3 to illuminate or turn off the stability-traction control disabled indicator (sliding car OFF icon) based upon the system state.

Refer to ABS/Brake/Stability-Traction Control System Indication description 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 Indicator

The IPC receives the tire pressure warning indicator message from the GWM over the HS-CAN3. The GWM receives the tire pressure warning indicator message from the BCM over the HS-CAN1.

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 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 warning indicator. The IPC flashes the TPMS warning indicator for 75 seconds then turns the indicator on solid.
