Indicator Light

Remove A/C control assembly. Disconnect indicator light 2-pin connector. Connect battery positive lead to terminal No. 1 (Red/Yellow wire) and negative battery lead to terminal No. 2 (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 ECU. See TEST 1 under SYSTEM TESTS. Repair or replace harness and connectors as necessary. If harness and connectors are okay, check ECU. See PIN VOLTAGE TESTS. If pin voltages are not within specification, replace ECU and retest system operation.
