BRAKE SYSTEM – TRACTION CONTROL SYSTEM (TRAC)
DIAGNOSTIC TROUBLE CODE CHART
If a malfunction code is displayed during the diagnostic trouble code check, check the circuit listed for that code in the table below and proceed to the relevant page.
HINT: If the TRAC indicator light lights up and the TRAC indicator light does not blink when the DTC is checked, check the blinking pattern of the ABS warning light and troubleshoot the ABS system.
