Air Conditioning Panel Assembly

INSPECTION

1. INSPECT AIR CONDITIONING PANEL SUB-ASSEMBLY (for Manual Air Conditioning)




a. Disconnect the connectors from the air conditioning panel sub-assembly and inspect the connectors on the wire harness side, as shown in the chart.
If the circuit is as specified, replace the air conditioning panel sub-assembly with a new one. If the circuit is not as specified, inspect the circuits connected to other parts.







b. Connect the connectors to the heater air conditioning panel sub-assembly and inspect the back side from the wire harness side, as shown in the chart.
If the circuit is as specified, replace the air conditioning panel sub-assembly with a new one. If the circuit is not as specified, inspect the circuits connected to other parts.




2. INSPECT ECM (for Manual Air Conditioning)




a. waveform 1: Measure the waveform between terminal LCKI (C23) of the ECM and body ground.

OK:
Waveform operate as shown in the illustration.

If the waveform is as specified, replace the ECM with a new one. If the waveform is not as specified, inspect the circuits connected to other parts.
