Trouble Shooting

The troubleshooting flowchart procedures assume that the cause of the problem is still present and the ABS indicator and/or system indicator is still on. Following the flowcharts when the ABS/TCS indicators and/or system indicators 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/TCS indicators and/or system indicators came on, such as during ABS or TCS control, after ABS or TCS control, when vehicle speed was at a certain speed, etc.

When the ABS or TCS 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 or TCS indicators and ABS/TCS system indicators do not come on.
