Normal Operation and Fault Conditions
With the ignition ON, the SASM sends messages to the GWM over the HS-CAN2 , the GWM relays thesemessages to the ABS module over the FD-CAN . If the ABS module does not receive these messageswithin the specified time frame, the ABS module sets Diagnostic Trouble Codes (DTCs). This can be dueto a steering angle sensor failure, a circuit failure on the HS-CAN or an excessive load on the network. Forinformation on the messages sent to the ABS module by the SASM , REFER to: ANTI-LOCK BRAKE SYSTEM (ABS) AND STABILITY CONTROL - SYSTEM OPERATION AND COMPONENT DESCRIPTION .
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |

| U0126:00 | Lost Communication With Steering Angle Sensor Module: No Sub Type Information | This DTC sets in the ABS module if any of the SASM messages are missing. This can be due to a SASM failure, acircuit failure on the HS-CAN or an excessive load on the network. The SASM is also known as the SCCM . |
