P0692-COOLING FAN 1 RELAY CONTROL CIRCUIT HIGH (CONTINUED) For the Engine circuit diagram (Refer to 9 - ENGINE - SCHEMATICS AND DIAGRAMS). For a complete wiring diagram Refer to Section 8W. • When Monitored: • Set Condition: 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 - 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. 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) 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 IPM 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. Is the voltage above 0 volts? Yes >> Repair the short to battery voltage in the (N201) Cooling Fan No.1 Relay Control circuit. Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) No >> Go To 3 3. LOW SPEED RADIATOR FAN RELAY RESISTANCE Measure the resistance of the Low Speed Radiator Fan Relay Coil. 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.
