Pinpoint Test Aa : U0293:00, U1026:00: Notes
Refer to Vehicle Dynamic Systems for schematic and connector information.
Normal Operation and Fault Conditions
NOTE:
The Hybrid / EV PCM is also known as the SOBDMC.
With the ignition ON, the SOBDMC sends messages to the ABS module through the GWM over the HS-CAN2. If the ABS module does not receive these messages within a certain time frame, the ABS module sets a DTC. For information on the messages sent to the ABS module by the SOBDMC, Refer to: Network Message Chart .
The SOBDMC monitors fault messages from the ABS module. When the ABS module sets DTC U0293:00, the SOBDMC sets a DTC and illuminates the MIL.
