11. Warning Light Illumination Pattern
A: INSPECTION
1) When the warning and/or indicator lights do not
illuminate in accordance with this illumination
pattern, there must be an electrical malfunction.
2) When the warning and/or indicator lights
remain constantly OFF, repair the warning and/or
indicator lights circuit or diagnosis circuit. <Ref. to
VDC-34, ABS WARNING LIGHT, VDC WARNING
LIGHT, VDC OPERATING INDICATOR LIGHT OR
VDC OFF INDICATOR LIGHT DOES NOT COME
ON., Diagnostics Chart with Diagnosis Connec-
tor.>
NOTE:
¼ Even though the ABS warning light does not go
out 1.5 seconds after it illuminates, the VDC sys-
tem operates normally when the warning light goes
out while driving at approximately 12 km/h (7
MPH). However, the Anti-lock brakes do not work
while the ABS warning light is illuminated.
¼ It may take a few minutes for the VDC OFF
indicator light to go out when the vehicle is
exposed for some time in a low temperature area.
This is not a problem because of low engine cool-
ant temperatures.
¼ If a vehicle wheel is stuck or free-spinning for
approximately 1 minute, power transfer fluctuation
to the remaining wheels will occur. Power transfer

conditions will differ from those occurring during
normal vehicle operation. The ABS sensor will
detect this condition. The ABS and VDC warning
lights will illuminate. If the vehicle is operated with
the four wheels lifted off the ground or with the four
wheels placed on rollers, the VDCCM will detect a
problem with the speed sensor and the ABS and
VDC warning lights may illuminate. In this case,
there is no abnormality. Clear the diagnostic code
from memory.
¼ When the engine is started and vehicle move-
ment begins, the VDCH/U motor pump and sole-
noid valve will operate for a few seconds. This
permits checking of VDC function. Normal motor
pump and solenoid valve operational noise will be
heard. Normal brake pedal kick back will be felt
when the brake pedal is depressed. In this case,
there is no abnormality.
