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.
Symptom Troubleshooting Index
When the vehicle has one of these symptoms, check for VSA diagnostic trouble codes (DTCs) with the HDS. If there are no DTCs, do the diagnostic procedure for the symptom, in the sequence listed, until you find the cause.
| Symptom | Diagnostic procedure |
|---|---|
| HDS does not communicate with the VSA modulator-control unit or the vehicle | Troubleshoot the DLC circuit |
| ABS indicator, brake system indicator, VSA indicator, or VSA OFF indicator do not come on at start-up (bulb check) |
|
| VSA cannot be turned OFF |
|
| VSA OFF indicator does not go off | Do the VSA sensor neutral position memorization (see YAW RATE-LATERAL ACCELERATION SENSOR REPLACEMENT ) |
| ABS indicator, brake system indicator, and VSA indicator do not go off |
