Compressor Clutch Relay: Description and Operation

AIR CONDITIONING SWITCH AND COMPRESSOR CLUTCH RELAY
OPERATION

- The air conditioning switch applies battery positive voltage to the engine control module when the air conditioning is switched ON.

-

When the air conditioning signals are input, the engine control module activates the idle air control motor, and also switches ON the powertransistor. As a result, current flows to the compressor clutch relay coil and the relay switch is switched ON; the air conditioning compressor'smagnetic clutch is activated.

TROUBLESHOOTING HINTS

If the air conditioning compressor's magnetic clutch is not activated when the air conditioning switch is switched on during idling, the cause isprobably a malfunction of the air conditioning control system.

INSPECTION

Using Scan Tool

<Air Conditioning Switch>

<Air Conditioning Compressor Clutch Relay>

HARNESS INSPECTION

-STEP 1. Measure the power supply voltage of the air conditioning circuit.

Engine control module connector: Disconnect

- Ignition switch: ON

- Air conditioning switch: ON

Voltage (V): 6 or higher

OK: STOPNG: Check the air conditioning circuit.
