Warning Messages

The message center warning messages alert the operator to possible concerns or malfunctions in the vehicle operating systems. Warning messages are generally associated with other observable outputs of the IPC (gauges, informational indicators and RTT indicators. For example, when the BCM detects a low brake fluid condition, the BCM sends the IPC a request through the GWM to illuminate the brake warning indicator and a request to display the LOW BRAKE FLUID message in the message center. This allows the message center to be a more informative supplement to the IPC gauges and indicators.

On GT350 vehicles only, the message center provides a warning message to indicate to the driver the brake pads are worn and require replacing. This is needed since the brake pads do not use the spring steel brake pad wear indicator used on other brake pads. When the brake pads are worn, the GWM sends the brake wear message request to the IPC over the HS-CAN3. The GWM receives the brake wear message request from the VDM over the HS-CAN2.

When a low brake fluid level condition exists, the BCM sends the brake fluid level low message request to the GWM over the HS-CAN1.

If the vehicle is set in factory mode, the system does not automatically exit the mode and must be manually set to either the transport or normal operation mode.

When the vehicle build is complete, the vehicle is set to transport mode. While in transport mode, the IPC displays TRANSPORT MODE CONTACT DEALER in the message center. Transport mode is used to reduce the drain on the battery during longer periods where the vehicle is not used. Various systems may be altered or are disabled when in the transport mode. The vehicle automatically reverts to normal operation mode after being driven 201 km (125 mi).

The instrument cluster provides messages to inform the driver about the oil life status, oil life reset status and when an oil change is required. The duration of the interval between oil changes is calculated in the PCM and varies due to driving conditions. The PCM assumes a base mileage of 16, 090 km (10, 000 mi) or 1 year for normal driving. However, this number is adjusted down for conditions such as high engine temperature, high engine rpm, use of flex fuel and possibly low oil level. The PCM calculates and provides the engine oil life percent message to the IPC. The IPC further converts the remaining oil life using the driver's configured oil life start value and displays the oil life percentage, indicating the remaining oil life.
