Pinpoint Test Cm: Abs Module Communication Concern With HEV-Pcm

WARNING: This page is about a different car, the 2021 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The HEV- PCM may also be known as the SOBDMC.

Normal Operation and Fault Conditions 

With the ignition ON, the HEV- PCM sends messages to the GWM over the HS-CAN1. The GWM relays these message to the ABS module over the HS-CAN2. 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 HEV- PCM 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 HEV- PCM, refer to the Network Message Chart  .

DTC Fault Trigger Conditions 

DTC Description Fault Trigger Condition
ABS U0594:00 Invalid Data Received From Hybrid/EV Powertrain Control Module "A": No Sub Type Information This DTC sets if the ABS module receives a fault message in the regenerative brake wheel torque message from the HEV- PCM.
