10.Warning Light Illumination Pattern
A: INSPECTION
1) When warning lights or indicator lights do not illuminate in accordance with this illumination pattern, there
must be an electrical malfunction.
2) When warning lights or indicator lights remain constantly OFF, check the combination meter circuit or CAN
communication circuit. VDC INDICATOR LIGHT DO NOT COME ON, Warning Light Illumination Pattern.>
3) When ABS warning light does not go off, check the combination meter circuit. WARNING LIGHT DOES NOT GO OFF, Warning Light Illumination Pattern.>
