Diagnostic Test
1.FA N C L U T C H
Disconnect the fan clutch harness connector.
Check connectors - Clean/repair as necessary.
Measure the resistance between the fan clutch (K160) driver circuit and
the fan speed (K690) sensor return circuit on the fan clutch assembly.
Is the resistance less than 10 Ohms?
Ye s>>
Replace the fan clutch.
Perform POWERTRAIN VERIFICATION TEST VER - 1
(DIESEL). (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/ENGINE CONTROL MODULE - DIAG-
NOSIS AND TESTING)

the fan speed sensor (K690) return circuit at the sensor harness con-
nector.
Is the resistance greater than 100K Ohms?
Ye s>>
Go To 5
No>>
Repair the (K160) Driver circuit shorted to (K690) Return
circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 1
(DIESEL). (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/ENGINE CONTROL MODULE - DIAG-
NOSIS AND TESTING)
5.(K160) DRIVER CIRCUIT SHORTED TO BATTERY NEGATIVE
Measure the resistance between the fan clutch (K160) driver circuit and
the battery negative.
Is the resistance greater than 100k Ohms?
Ye s>>
Go To 6
No>>
Repair the (K160) Driver circuit shorted to battery negative.
Perform POWERTRAIN VERIFICATION TEST VER - 1

P0500-NO VEHICLE SPEED SENSOR SIGNAL
For a complete wiring diagramRefer to Section 8W.

When Monitored:
While the engine is running.
Set Condition:
The ECM indicates signals of motion; however, the VSS does not.
Possible Causes
VEHICLE SPEED (B22) SIGNAL CIRCUIT SHORTED TO VOLTAGE
VEHICLE SPEED (B22) SIGNAL CIRCUIT OPEN BETWEEN CAB AND ECM
VEHICLE SPEED (B22) SIGNAL CIRCUIT SHORTED TO GROUND
ECM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
Diagnostic Test
1.VEHICLE SPEED SENSOR (B22) SIGNAL CIRCUIT SHORT TO VOLTAGE
Turn the ignition off.
Disconnect the ECM harness connectors.
Disconnect the ABS/RWAL Module harness connector.
Ignition on, engine not running.
Measure the voltage of the Vehicle Speed (B22) signal circuit in the
ABS/RWAL or ECM harness connector.
Is the voltage above 4.9 volts?
Ye s>>
Repair the short to voltage in the Vehicle Speed (B22) Sig-
nal circuit between the CAB and ECM.
Perform POWERTRAIN VERIFICATION TEST VER - 1
(DIESEL). (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/ENGINE CONTROL MODULE - DIAG-
NOSIS AND TESTING)
No>>
Go To 2

2.VEHICLE SPEED SENSOR (B22) SIGNAL CIRCUIT OPEN BETWEEN CAB AND ECM
Turn the ignition off.
Measure the resistance of the Vehicle Speed (B22) signal circuit
between the ECM harness connector and the ABS/RWAL harness con-
nector.
Is the resistance above 5.0 ohms?
Ye s>>
Repair the open in the Vehicle Speed (B22) signal circuit
between the CAB and ECM.
Perform POWERTRAIN VERIFICATION TEST VER - 1
(DIESEL). (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/ENGINE CONTROL MODULE - DIAG-
NOSIS AND TESTING)
No>>
Go To 3
3.VEHICLE SPEED SENSOR (B22) SIGNAL CIRCUIT SHORT TO GROUND
Measure the resistance between ground and the Vehicle Speed (B22)
signal circuit at the ECM harness connector.
Istheresistancebelow100ohms?
Ye s>>
Repair the short to ground in the Vehicle Speed (B22) sig-
nal circuit between the CAB and ECM.
Perform POWERTRAIN VERIFICATION TEST VER - 1
(DIESEL). (Refer to 8 - ELECTRICAL/ELECTRONIC CON-

P0514-BAT TEMPERATURE SENSOR RATIONALITY
For a complete wiring diagramRefer to Section 8W.

When Monitored:
While the engine is running.
Set Condition:
The ECM does not read a change in value from the sensor over time.
Possible Causes
BATTERY TEMP SENSOR
INTERMITTENT CONDITION
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
Diagnostic Test
1.BATTERY TEMP SENSOR
Remove the temperature sensor and reconnect the wiring harness connectorto the sensor.
Monitor scan tool, while heating the sensor with an external heat source (DO NOT USE OPEN FLAME).
Does the reading from the sensor increase at least 5 degrees F. on the scan tool?
Ye s>>
Refer to the INTERMITTENT CONDITION Symptom (Diagnostic Procedure). (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
No>>
Replace the battery temperature sensor.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL). (Refer to 8 - ELECTRICAL/ELEC-
TRONIC CONTROL MODULES/ENGINE CONTROL MODULE - DIAGNOSIS AND TESTING)
