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.
