Combination Meter Circuit
Inspect the combination circuit with the connector connected. Connect connector "A" and "B" from the combination meter and inspect the connectors on the wiring harness side. See CONNECTOR IDENTIFICATION . See INSPECTING COMBINATION METER CIRCUIT table. If the circuit is not as specified, check the wiring diagram and inspect the circuits connected to other parts.
