Pinpoint Test Ck: Abs Module Communication Concern With The IPMB

Normal Operation and Fault Conditions 

The IPMB is an internal component of the Advanced Driver Assistance Systems (ADAS) module. The IPMB may also be known as the Camera Module - Rear.

With the ignition ON, the Advanced Driver Assistance Systems (ADAS) module sends messages to the ABS module over the FD-CAN. If the ABS module does not receive these messages within the allotted time frame or if the messages contain invalid data, the module sets a DTC. This can be due to a Advanced Driver Assistance Systems (ADAS) module failure, a circuit failure on the network or an excessive load on the network. For information on the messages sent to the ABS module by the IPMB and Advanced Driver Assistance Systems (ADAS) module, refer to Network Message Chart  in the service information.

DTC Fault Trigger Conditions 

DTC Description Fault Trigger Condition
