ANTI-LOCK BRAKE SYSTEM DIAGNOSTIC TROUBLE CODE CHART

Tech Tips

If no abnormality is found when inspecting parts, inspect the skid control ECU and ground points for poor contact.
If a trouble code is output during the DTC check, check the trouble areas indicated by the DTC. For details of each code, refer to the "See page" for the respective "DTC Code" in the DTC chart.
When 2 or more DTCs are output, perform circuit inspections one by one until the problem is identified.
Inspect the fuses and relays before investigating the trouble areas shown in the table below.
