Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Normal Operation and Fault Conditions
With the ignition ON, the SECM sends messages to the SASM over a private CAN. If the SASM does not receive these messages within a certain time frame (usually less than 1 second), the SASM sets DTCs. For information on the messages sent to the SASM by the SECM, refer to the Network Message Chart in Description and Operation of the Anti-Lock Brake System (ABS) and Stability Control article.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U0130:00 | Lost Communication With Steering Effort Control Module: No Sub Type Information | Sets in continuous memory and on-demand when the SASM detects any of the SECM messages are missing. This can be due to a SECM failure, a circuit failure on the private CAN or an excessive load on the network. |
