Mitsubishi Montero (1998+). Manual - part 72

3) If radiator fan and condenser fan operate in all speeds

except high, check appropriate high speed relay. See COMPONENT TESTS.

See WIRING DIAGRAMS. If high speed relay is okay, check PCM. See

appropriate G - TESTS W/CODES article in ENGINE PERFORMANCE.

4) To confirm radiator fan or condenser fan operation, see

appropriate FAN OPERATING MODE (GALANT) table. If fan operation is not

as specified, check wiring harness for opens or shorts. Repair as

necessary.

(1) - A/C request switch is turned off.

(2) - Approximate vehicle speed/coolant temperature or less.

(3) - Approximate vehicle speed/coolant temperature or more.

(4) - A/C request switch is turned on.

NOTE: Operation of radiator and condenser fans is controlled by

vehicle Powertrain Control Module (PCM). Based on vehicle

speed, coolant temperature and A/C operation request, PCM

will command low, medium or high speed fan operation.

1) If only the radiator fan does not operate, check fusible

link No. 5 (30-amp) located in engine compartment relay box. If only

the condenser fan does not operate, check fusible link No. 2 (100-amp)

and dedicated fuse No. 1 (25-amp) located in engine compartment relay

box. See WIRING DIAGRAMS. Repair as necessary.

2) If fusible links and dedicated fuse are okay, check

appropriate fan relay and/or fan motor for proper operation. See

COMPONENT TESTS. See WIRING DIAGRAMS. If fan relay and motor are okay,

check PCM. See appropriate G - TESTS W/CODES article in ENGINE

PERFORMANCE.

1) If neither the radiator fan nor the condenser fan operate,

check fusible link No. 5 (40-amp). See WIRING DIAGRAMS. If only the

condenser fan does not operate, check dedicated fuse No. 8 (20-amp).

2) If the condenser fan operates in all speeds except low and

A/C compressor clutch does not enter the ON state, check for A/C

compressor lock controller unit output signal. If the A/C compressor

clutch does enter the ON state, check condenser fan low speed relay

operation.

3) If the radiator fan and the condenser fan operate in all

speeds except high, check PCM. See appropriate G - TESTS W/CODES

article in ENGINE PERFORMANCE. If fan operation is not as specified,

check wiring harness for opens or shorts. Repair as necessary.
