VDC(diag)-26
Warning Light Illumination Pattern
VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)
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
DO NOT COME ON, Warning Light Illumination
Pattern.> <Ref. to VDC(diag)-28, ABS WARNING
LIGHT DOES NOT COME ON, Warning Light Illu-
mination Pattern.> <Ref. to VDC(diag)-28, HILL
START ASSIST WARNING LIGHT DOES NOT
COME ON, Warning Light Illumination Pattern.>
3) When ABS warning light and hill start assist
warning light do not go off, check the combination
meter circuit. <Ref. to VDC(diag)-29, ABS WARN-
ING LIGHT DOES NOT GO OFF, Warning Light Il-
lumination Pattern.>
4) When the VDC indicator light, VDC warning light
and VDC OFF indicator light do not go off, check
the combination meter circuit or CAN communica-
tion circuit. <Ref. to VDC(diag)-29, VDC INDICA-
TOR LIGHT DOES NOT GO OFF, Warning Light
Illumination Pattern.> <Ref. to VDC(diag)-30, VDC
WARNING LIGHT AND VDC OFF INDICATOR
LIGHT DO NOT GO OFF, Warning Light Illumina-
tion Pattern.>
NOTE:
• Even though the ABS warning light does not go
off after 2 seconds from ABS warning light illumina-
tion, the ABS system operates normally when the
warning light goes off while driving at approximate-
ly 12 km/h (7 MPH). However, the ABS system
does not work while the ABS warning light is illumi-
nated.
• 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.
