1) When warning lights or indicator lights do not il-
luminate in accordance with this illumination pat-
tern, there must be an electrical malfunction.
2) When warning lights or indicator lights remain
constantly OFF, check the combination meter cir-
cuit or CAN communication circuit. <Ref. to
VDC(diag)-27, VDC WARNING LIGHT, VDC OFF
INDICATOR LIGHT AND VDC INDICATOR LIGHT

3) When ABS warning light does not go off, check
the combination meter circuit. <Ref. to VDC(diag)-
31, ABS WARNING LIGHT DOES NOT GO OFF,

NOTE:
• Even though the ABS warning light does not go
off after 1.5 seconds from ABS warning light illumi-
nation, the ABS system operates normally when
the warning light goes off while driving at approxi-
mately 12 km/h (7 MPH). However, the ABS sys-
tem does not work while the ABS warning light is
illuminated.
• It may take several minutes before VDC warning
light and VDC OFF indicator light goes off if the ve-
hicle is parked under low temperature for a speci-
fied time. This is not defective because it is resulted
from low engine coolant temperature.
• With the vehicle jack-up/lift-up or set on free roll-
ers, when the wheels lock or spin after starting the
engine, ABS warning light, VDC warning light and
VDC OFF indicator light may illuminate because
VDCCM&H/U detects the abnormal conditions
from ABS wheel speed sensors. In this case, this is
not a malfunction. Perform the clear memory mode.
