DIAGNOSIS SYSTEM
1. DESCRIPTION
(a) Release the parking brake pedal.
(b) Check the warning lights.
When ignition switch is turned ON, check that the
ABS warning light and brake warning light come on
for 3 seconds.
HINT:
• When parking brake is applied or the level of the
brake fluid is low, the brake warning light comes
on.
• If the indicator check result is not normal,
proceed to troubleshooting for the light circuit
below.
DTC CHECK / CLEAR
1. DTC CHECK/CLEAR (WHEN USING SST CHECK
WIRE):
(a) DTC check
(1) Using SST, connect terminals TC and CG of the
DLC3.
SST 09843-18040
(2) Turn the ignition switch to the ON position.
(3) Read the DTCs from the ABS warning light on
the combination meter.
HINT:
If no code appears, inspect the TC and CG
terminal circuit and the ABS warning light circuit.
