Ignition OFF. Connect PAD Indicator C9801 (if previously disconnected).

Inspect connector(s) (including any inline connectors) for corrosion, loose or spread terminals and loose or frayed wire connections at terminals. Inspect wire harness for any damage, pinched, cut or pierced wires. Inspect RCM C310A and C310B Connector Position Assurance (CPA) lever/lock for correct operation. Repair any concerns found.
