cooling fan wiring TOYOTA CAMRY 2000 Service Repair Manual

IDLE SPEED INSPECTION
1. INITIAL CONDITIONS
(a) Engine at normal operating temperature
(b) Air cleaner installed
(c) All pipes and hoses of air induction system connected
(d) All vacuum lines properly connected
(e) MFI/SFI system wiring connectors fully plugged
(f) All operating accessories switched OFF
(g) Ignition timing set correctly
(h) Transmission in neutral position
2. CONNECT TACHOMETER
Connect the test probe of a tachometer to terminal IG
(±) of the data link connector 1.
NOTICE:
wNever allow the tachometer terminal to touch
ground as it could result in damage to the Igniter
and/or ignition coil.
wAs some tachometers are not compatible with this
ignition system, we recommend that you confirm
the compatibility of yours before use.
(b) Check the idle speed.
Idle speed (w/ Cooling fan OFF):
750+50 rpm
If the idle speed is not as specified, check the IAC
system.
4. DISCONNECT TACHOMETER 3. INSPECT IDLE SPEED
(a) Race the engine at 2,500 rpm for approx. 90 seconds.
