Pinpoint Test J: Abs Module Communication Concern With SASM
Normal Operation and Fault Conditions
With the ignition ON, the SASM sends messages to the GWM over the HS-CAN2. The GWM relays these messages to the ABS module over the FD-CAN. 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 SASM 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 SASM, refer to the Network Message Chart .

| DTC | Description | Fault Trigger Condition |
|---|---|---|
| ABS U0126:00 | Lost Communication With Steering Angle Sensor Module: No Sub Type Information | This DTC sets when the ABS module does not receive any messages from the SASM within the allowed time. |
