With the ignition ON, the RCM sends messages to the ABS module over the public HS-CAN and a private HS-CAN. If the ABS module does not receive these messages within the specified time frame, the module sets a DTC. This can be due to a RCM failure, a circuit failure on the public or private HS-CAN, or an excessive load on the network.
- DTC U0151:00 (Lost Communication with Restraints Control Module: No Sub Type Information) - a continuous memory DTC set by the ABS module if it does not receive yaw or other sensor messages from the RCM for 5 seconds or longer.
This pinpoint test is intended to diagnose the following:
- Communication network concern
- RCM
