System Inspection

INSPECTION




1. INSPECT CLIMATE CONTROL SWITCH INDICATOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 14 and negative (-) lead to terminal 6.
b. Check that the indicator lights up when climate controls witch is turned ON.
If climate indicator does not light up, replace climate control switch.

2. INSPECT CLIMATE CONTROL SWITCH OPERATION
a. ():Front passenger side:
Measure resistance between terminals 1(15) and 13 (17) is approx. 5.0 kohms




b. ():Front passenger side:
Measure resistance between terminals 12 (16) and 13 (17) at switch each position as shown in the chart.
If resistance is not as specified, replace the climate control switch.







3. INSPECT CLIMATE CONTROL SWITCH CIRCUIT
Disconnect the connector from the climate control switch and inspect the connector on the wire harness side, as shown in the chart below.
If the circuit is not as specified, replace the wire harness.







4. INSPECT THERMISTOR RESISTANCE (): Seat cushion side:
Measure resistance between terminals 2(1) and 3(2) of climate controller at each temperature, as shown in the chart.

HINT: As the temperature increase, the resistance decreases. If the resistance is not as specified, replace the climate controller








5. INSPECT CLIMATE CONTROL ECU CIRCUIT
Disconnect the connector from the climate control ECU and inspect connector on the wire harness side, as shown in the chart.
If circuit is not as specified, replace the repair or replace the wire harness.
