Pinpoint Test BZ: Abs (Anti-Lock Brake System) Module Communication Concern With The SODL (Side Obstacle Detection Control Module LH) Or SODR (Side Obstacle Detection Control Module RH)
REFER to: MODULE COMMUNICATIONS NETWORK for schematic and connector information.
Normal Operation and Fault Conditions
With the ignition ON, the SODL and SODR send messages to the ABS module through the GWM over the CAN. If the ABS module does not receive these messages within a certain time frame, the ABS module sets one or more Diagnostic Trouble Codes (DTCs). This can be due to a SODL or SODR failure, a circuit failure on the CAN or an excessive load on the network. For information on the messages sent to the ABS module by the SODL and SODR, 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 U0232:87 | Lost Communication With Side Obstacle Detection Control Module "A": Missing Message | Sets when the ABS module does not receive messages from the SODL in the allowed time. This can be due to a SODL failure, a circuit failure on the network or an excessive load on the network. |
| ABS U0233:87 | Lost Communication With Side Obstacle Detection Control Module "B": Missing Message | Sets when the ABS module does not receive messages from the SODR in the allowed time. This can be due to a SODR failure, a circuit failure on the network or an excessive load on the network. |
