CIRCUIT OPERATION
The fan control module is powered from fusible link number 2. The PCM judges the required revolution speed of radiator fan motor and
condenser fan motor using the input signals transmitted from A/C switch,
automatic compressor controller, vehicle speed sensor and engine coolant
temperature sensor. The PCM activates the fan control module to drive the
radiator fan motor and condenser fan motor.
TECHNICAL DESCRIPTION
The cause could be a malfunction of the fan control module power supply or
ground circuit. The cause could also be a malfunction of the fan control module or the PCM.
TROUBLESHOOTING HINTS
Malfunction of fusible link Malfunction of fan control relay Malfunction of MFI relay Malfunction of fan control module Malfunction of PCM Damaged wiring harness or connector
DIAGNOSIS Required Special Tools:
MB991223: Harness Set MB991923: Power Plant ECU Check Harness
STEP 1. Check the circuit at fan control module connector A-23 (terminal
3).
1. Disconnect fan control module connector A-23, and measure at the
harness side connector.

2. Measure the voltage between terminal number 3 and ground.
When the ignition switch is turned to the "ON" position, voltage
should measure battery positive voltage.
