INSTRUMENT CLUSTER (CCN)
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Fuel Level Sensor
and the Instrument Cluster (CCN).
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out or corroded terminals.
Refer to any Technical Service Bulletins that may apply.
Were any problems found?
Yes
>> Repair as necessary.
Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).
No
>> Replace and program the Instrument Cluster (CCN) in accordance with the Service Information.
Perform the PCM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

PM
•
When Monitored:
With the ignition on. Battery voltage greater than 10 volts.
•
Set Condition:
An open or shorted circuit is detected in the Low/High Rad Fan Control circuit. One Trip Fault. Three good
trips to turn off the MIL.
Possible Causes
(A16) FUSED (B+) CIRCUITS
(N201) LOW/HIGH/HIGH RAD FAN CONTROL CIRCUIT SHORTED TO BATTERY VOLTAGE
(N201) LOW/HIGH RAD FAN CONTROL CIRCUIT OPEN
(N201) LOW/HIGH RAD FAN CONTROL CIRCUIT SHORTED TO GROUND
LOW/HIGH RAD FAN RELAY
TOTALLY INTEGRATED POWER MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.
RADIATOR COOLING FAN MODULE OPERATION
Ignition on, engine not running.
With a scan tool, select Radiator Cooling Fan Relay #1 Control State to actuate the Cooling Fan (Low/High).
Is the one Cooling Fan 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.
(A16) FUSED B+ CIRCUIT
Ignition on.
Disconnect the Low/High Rad Relay harness connector.
Using a 12-volt test light connected to ground, probe the (A16) Fused
B+ circuit in the Low/High Rad Relay harness connector.
Does the test light illuminate brightly?
Yes
>> Go To 3
No
>> Repair the (A16) Fused B+ circuit. Inspect the related fuse
and repair as necessary.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to
9 - ENGINE - STANDARD PROCEDURE)

3.
LOW/HIGH RAD FAN CONTROL CIRCUIT
Turn the ignition on, engine not running.
With a scan tool, select Radiator Cooling Fan Relay #1 Control State,
Toggle, to actuate the Cooling Fan (Low/High).
Using a 12-volt test light connected to battery voltage, probe the (N201)
Low/High Rad Fan Control circuit in the Low/High Rad Relay harness
connector.
Does the test light illuminate brightly and flash on and off?
Yes
>> Replace the Low/High Rad Fan Relay.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to
9 - ENGINE - STANDARD PROCEDURE)
No
>> Go To 4
4.
(N201) LOW/HIGH RAD FAN CONTROL CIRCUIT SHORTED TO BATTERY VOLTAGE
Disconnect the TIPM C11 harness connector.
Using a voltmeter, measure the voltage of the (N201) Low/High Rad
Fan Control circuit in the Low/High Rad Relay harness connector.
Is there voltage present?
Yes
>> Repair the short to voltage in the (N201) Low/High Rad Fan
Control circuit
Perform the POWERTRAIN VERIFICATION TEST. (Refer to
9 - ENGINE - STANDARD PROCEDURE)
No
>> Go To 5
