ANTI-LOCK BRAKE SYSTEM (w/ Rear Differential Lock) DIAGNOSTIC TROUBLE CODE CHART

Note

When removing parts, turn the ignition switch OFF.

Tech Tips


  • If an abnormality is not found when inspecting parts, inspect the ECU and ground points for poor contact.

  • If a malfunction code is displayed during the DTC check, check the circuit listed for that code. For details of each code, refer to the page number in the chart below.

  • When 2 or more DTCs are detected, perform inspections on each circuit until the problem is identified.
