Indicator Light Circuit

Remove A/C control assembly. Disconnect indicator light 2-pin connector. Connect battery positive lead to terminal No. 1 (Violet wire) and negative battery lead to terminal No. 10 (White/Black wire). If indicator light does not come on, replace light. If indicator light comes on, inspect wire harness and connectors between light and Electronic Control Unit (ECU). Repair harness or connectors as necessary. If harness and connectors are okay, check ECU. See PIN VOLTAGE TESTS . If found to be defective, replace ECU and retest system.
