COOLING FAN MOTOR INSPECTIONA6E362215025202MZR-CD (RF Turbo)
1. Verify that the battery is fully charged.
•Charge if necessary. (See G–6 BATTERY RECHARGING.)
2. Connect battery positive voltage and an ammeter to the cooling fan motor connector.
3. Verify that the cooling fan motor operates smoothly at the standard current draw.
•If not as specified, replace the cooling fan motor.

IDLE SPEED INSPECTION (4WD)A6E390802000201
Note
•Ignition timing is not adjustable.
•Ignition timing verification requires WDS or equivalent.
1. Turn off the electrical loads.
2. Warm up the engine as follows.
(1) Start the engine.
(2) Maintain the engine speed at approx. 3,000 rpm until the cooling fans start to operate.
(3) Release the accelerator pedal.
(4) Wait until the cooling fans stop.
3. Verify that the idle speed (WDS: RPM PID) is within the specification using WDS or equivalent.
Idle speed
*1 : Excludes temporary idle speed drop just after the electrical loads are turned on.
*2 : Blower motor is operating at high speed. Headlight switch is turned on. Rear window defroster switch is turned
on. Cooling fans are operating.
