Inspect the combination meter circuit plate. See CONNECTOR IDENTIFICATION . See INSPECTING COMBINATION METER ECU TO GAUGES CIRCUIT table. If the circuit is not as specified, inspect the gauge or meter. Then recheck the system. If the circuit is not as specified, replace the circuit plate.INSPECTING COMBINATION METER ECU TO GAUGES CIRCUIT

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
