P0692-COOLING FAN 1 RELAY CONTROL CIRCUIT HIGHP0692-Cooling Fan 1 Relay Control Circuit High:
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.
Diagnostic Test
1. LOW SPEED RADIATOR FAN RELAY OPERATION
Ignition on, engine not running.
With a scan tool, actuate the Low Speed Radiator Fan Relay.
Q: Is the Cooling Fan Relay operating?
YES: Refer to the INTERMITTENT CONDITION Diagnostic Procedure. Component Tests and General Diagnostics
Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test
NO: Go To 2
2. (N201) COOLING FAN NO.1 RELAY CONTROL CIRCUIT SHORTED TO BATTERY VOLTAGE
Turn the ignition off.
Remove the Low Speed Radiator Fan Relay.
Disconnect the FCM 49 way harness connector.
Ignition on, engine not running.
Measure the voltage on the (N201) Cooling Fan No.1 Relay Control Circuit at the Relay terminal.
Q: 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 VER - 1. Body Verification Test
NO: Go To 3
3. LOW SPEED RADIATOR FAN RELAY RESISTANCE
Measure the resistance of the Low Speed Radiator Fan Relay Coil.
Q: Is the resistance between 60 to 80 ohms?
YES: Go To 4
NO: Replace the Low Speed Radiator Fan Relay. Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test
4. FRONT CONTROL MODULE
NOTE: Before continuing, check the FCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits.
Q: Were there any problems found?
YES: Repair as necessary. Perform BODY VERIFICATION TEST VER - 1. Body Verification Test
NO: Replace Front Control Module. Perform BODY VERIFICATION TEST VER - 1. Body Verification Test
