Warning Light Illumination Pattern
VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)
4) When the VDC indicator light, VDC warning light and TCS OFF indicator light do not go off, check the com-
bination meter circuit or CAN communication circuit. NOT GO OFF, Warning Light Illumination Pattern.>
NOTE:
•Even though the ABS warning light does not go off after 1.5 seconds from ABS warning light illumination,
the ABS system operates normally when the warning light goes off while driving at approximately 12 km/h (7
MPH). However, the ABS system does not work while the ABS warning light is illuminated.
•It may take several minutes before VDC warning light and TCS OFF indicator light goes off if the vehicle
is parked under low temperature for a specified time. This is not defective because it is resulted from low en-
gine coolant temperature.
•With the vehicle jack-up/lift-up or set on free rollers, when the wheels lock or spin after starting the engine,
ABS warning light, VDC warning light and TCS OFF indicator light may illuminate because VDCCM&H/U de-
tects the abnormal conditions from ABS wheel speed sensors. In this case, this is not a malfunction. Perform
the clear memory mode.
B: VDC WARNING LIGHT, TCS OFF INDICATOR LIGHT AND VDC INDICATOR
LIGHT DO NOT COME ON
DETECTING CONDITION:
•Defective combination meter
•Defective CAN communication
TROUBLE SYMPTOM:
When the ignition switch is turned to ON (engine OFF), VDC indicator light, VDC warning light and TCS OFF
indicator light do not come on.
NOTE:
When pressing the TCS OFF switch for more than 10 seconds, the TCS OFF indicator light goes off and can-
not operate any more. When turning the ignition switch from OFF to ON, the OFF operation enabled status
is restored.
Step Check Yes No
