P0692-COOLING FAN 1 RELAY CONTROL CIRCUIT HIGH

For a complete wiring diagram Refer to Section 8W.

When Monitored:
Ignition on with the Cooling Fan No.1 Relay powered on.
Set Condition:
The FCM detects the Cooling Fan No.1 Relay voltage above the acceptable voltage at the FCM. The circuit is continuously monitored.

Possible Causes

(N201) COOLING FAN NO.1 RELAY CONTROL CIRCUIT SHORTED TO BATTERY VOLTAGE

LOW SPEED RADIATOR FAN RELAY

FRONT CONTROL MODULE

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

1.LOW SPEED RADIATOR FAN RELAY OPERATION

Is the Cooling Fan Relay operating?

Yes

Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

2.(N201) COOLING FAN NO.1 RELAY CONTROL CIRCUIT SHORTED TO BATTERY VOLTAGE

Is the voltage above 0 volts?

Yes

Repair the short to battery voltage in the (N201) Cooling Fan No.1 Relay Control circuit.
Perform BODY VERIFICATION TEST. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)

3.LOW SPEED RADIATOR FAN RELAY RESISTANCE

Is the resistance between 60 to 80 ohms?

Yes

Replace the Low Speed Radiator Fan Relay.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

4.FRONT CONTROL MODULE

NOTE: Before continuing, check the FCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

Were there any problems found?

Yes

Replace Front Control Module per Service Information.
Perform BODY VERIFICATION TEST. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
