E. Measure the resistance between terminal 3 (RETURN) on the Coolant Temperature Control Module connector and terminal 2 (RETURN) on the Coolant Pump Outlet Temperature Sensor connector.
Open Circuit
Result: There were less than 10 Ohms of resistance between the Engine Coolant Pump Outlet Temperature Sensor circuit wires.
Proceed to Test Step 3.
Result: There were more than 10 Ohms of resistance on any one of the Engine Coolant Pump Outlet Temperatures Sensor circuit wires.
Repair: There is an open in the wiring harness. Repair the wiring or replace the harness. Verify that the problem is resolved.
Proceed to Test Step 10.
3. Check for Short Circuits in the Engine Coolant Pump Outlet Temperature Sensor Wiring Harness
A. Turn the keyswitch to OFF.
B. Disconnect the Engine Coolant Pump Outlet Temperature Sensor wiring harness from the sensor.
C. Disconnect the wiring harness connector from the Coolant Temperature Control Module.
D. Measure the resistance between terminal 10 (SIGNAL) on the Coolant Temperature Control Module connector and a good chassis ground.
E. Measure the resistance between terminal 3 (RETURN) on the Coolant Temperature Control Module connector and a good known good chassis ground.
Short Circuit
Result: There were more than 100 K Ohms of resistance between the connector terminal and ground on both of the Engine Coolant Pump Outlet Temperature Sensor circuit wires.
Proceed to Test Step 4.
Result: There were less than 100 K Ohms of resistance between the connector terminal and ground on any one of the Engine Coolant Pump Outlet Temperatures Sensor circuit wires.
Repair: There is a short circuit to ground in the wiring harness.
Verify that the problem is resolved
Proceed to Test Step 10.
4. Check for Short Circuits in the Engine Coolant Pump Outlet Temperature Sensor Wiring Harness
A. Turn the keyswitch to OFF.
B. Disconnect the Engine Coolant Pump Outlet Temperature Sensor wiring harness from the sensor.
C. Disconnect the wiring harness connector from the Coolant Temperature Control Module.
D. Measure the resistance between terminal 10 (SIGNAL) on the Coolant Temperature Control Module connector and all other pins in the Coolant Temperature Control Module connector.
E. Measure the resistance between terminal 3 (RETURN) on the Coolant Temperature Control Module connector and all other pins in the Coolant Temperature Control Module connector.
Short Circuit
Result: There were more than 100 K Ohms of resistance between all the Engine Coolant Pump Outlet Temperature Sensor circuit wires.
Repair: A failed Engine Coolant Pump Outlet Temperature Sensor has been detected. Replace the Engine Coolant Pump Outlet Temperature Sensor.
Proceed to Test Step 10.
Result: There were less than 100 K Ohms of resistance between any of the Engine Coolant Pump Outlet Temperatures Sensor circuit wires.
Repair: There is a pin to pin short circuit in the harness. Repair the wiring or replace the harness.
Verify that the problem is resolved.
Proceed to Test Step 10.
5. Check the Part Number of the Component
A. Locate the part number for the component that was identified by the "System Communication Status". Check to see if the part number is correct for the application.
Part Number
Result: The part number is incorrect for the application.
Repair: Replace the component with the correct part number.
Proceed to Test Step 10.
Result: The part number is correct for the application.
Proceed to Test Step 6.
6. Check for Incorrect Configuration Parameters
