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.
Trouble Shooting
The troubleshooting flowchart procedures assume that the cause of the problem is still present and the ABS indicator and/or VSA system indicator is still on. Following the flowcharts when the ABS indicator and/or VSA system indicator DOES NOT come on can result in incorrect diagnosis. The connector illustrations show the female terminal connectors with a single outline and the male terminal connectors with a double outline.
Question the customer about the conditions when the problem occurs, and try to reproduce the same conditions for troubleshooting. Find out when the ABS indicator and/or VSA system indicator came on, such as during ABS control, after ABS control, when vehicle speed was at a certain speed, etc.
When the ABS indicator or VSA system indicator does not come on during the test drive, but troubleshooting is performed based on the DTC, check for loose connectors, poor contact of the terminals, etc. before you start troubleshooting. After troubleshooting, clear the DTC, and test drive the vehicle. Make sure the ABS indicator and VSA system indicator do not come on.
