1. Disconnect the 16P connector (2) from control panel switch.
2. Turn the main switch to "ON" position.
3. Measure the voltage with a voltmeter across the terminal o and
terminal n.
4. If the voltage differs from the battery voltage, the wiring harness,
A/C relay or fuse is faulty.

1. Measure the voltage with a voltmeter across the terminal k and
chassis.
2. Turn the main switch to "ON" position.
3. Turn the blower switch to "ON" position.
4. Press the air conditioner switch to set it to "OFF" position
(indicator : OFF), and then measure a voltage using a circuit
tester.
5. Press the air conditioner switch to set it at "ON" position
(indicator : ON), and then measure a voltage using a circuit
