Pinpoint Test Ck: Abs Module Communication Concern With The IPMB

Normal Operation and Fault Conditions 

With the ignition ON, the IPMB sends messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within the allotted time frame, the module sets a DTC. This can be due to an IPMB 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, REFER to: Anti-Lock Brake System (ABS) and Stability Control - System Operation and Component Description .

DTC Fault Trigger Conditions 

DTC Description Fault Trigger Condition
ABS U023B:00 Lost Communication With Image Processing Module B: No Sub Type Information This DTC sets when the ABS module does not receive any messages from the IPMB within the allowed time.
