SchematicTest Step 1. Check for Connector Damage.
Turn the ECS to the OFF/RESET position.
Turn the battery disconnect switch to the OFF position.
Thoroughly inspect the ECM connectors J1/P1 and J2/P2. Inspect all of the other connectors. Refer to the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the circuit.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the customer connector (allen head screw) for the proper torque of 2.25 0.25 N m (20 2 lb in).
Check the harness and the wiring for abrasion and for pinch points.Expected Result:All connectors, pins, and sockets are completely coupled and/or inserted. The harness and wiring should be free of corrosion, of abrasion or of pinch points.Results:
OK - The connectors and wiring are okay. Proceed to test step 2.
Not OK - The connectors and/or wiring are not okay.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 2. Check for a Short Circuit in the Wiring Harness.
Disconnect ECM connector J1/P1 and all of the digital sensors.
Measure the resistance between the digital supply P1-35 (700-OR) and the digital return P1-29 (998-BR) on connector P1.
Measure the resistance between the digital supply P1-35 (700-OR) and engine ground.
Measure the resistance between the digital return P1-29 (998-BR) and engine ground.Expected Result:The resistance should be greater than 20,000 Ohms for each measurement.Results:
OK - The resistance is greater than 20,000 Ohms. Proceed to test step 3.
Not OK - The resistance is less than 20,000 Ohms.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 3. Check the Digital Supply Voltage at the ECM.
Remove the wire P1-35 from the ECM connector P1. Install a jumper wire into the socket for P1-35.
Remove the wire P1-29 from the ECM connector P1. Install a jumper wire into the socket for P1-29.Note: If you remove the sensor common from the ECM, an open circuit diagnostic code will be generated for all sensors that use the sensor common. Troubleshoot the original code. Delete the logged diagnostic codes when you are finished.
Turn the battery disconnect switch to the ON position.
Turn the ECS to the STOP position. The engine should be off.
Measure the voltage between the digital sensor supply P1-35 and the digital sensor return P1-29 at the wire jumpers.
Turn the ECS to the OFF/RESET position.
Turn the battery disconnect switch to the OFF position.
Remove the wire jumpers and reconnect ECM connector J1/P1.Expected Result:The supply voltage should be 8.0 0.4 VDC.Results:
OK - The supply voltage is 8.0 0.4 VDC. The digital sensor supply is producing the correct voltage. Proceed to test step 4.
Not OK - The supply voltage is not 8.0 0.4 VDC. The digital sensor is not producing the correct voltage.Repair: Perform the diagnostic functional test Troubleshooting, "Electrical Power Supply".STOPTest Step 4. Check the Digital Sensor Supply Voltage at the Sensor Connector.
Turn the battery disconnect switch to the ON position.
Turn the ECS to the STOP position. The engine should be off.
Measure the digital sensor supply voltage between the digital supply terminal-A (700-OR) and the digital return terminal-B (998-BR) at all of the digital sensors.Note: If the sensor is disconnected from the harness, an open circuit diagnostic code will be generated for that sensor. Troubleshoot the original code. Delete the logged diagnostic codes when you are finished.
Turn the ECS to the OFF/RESET position.
Turn the battery disconnect switch to the OFF position.Expected Result:The supply voltage should be 8.0 0.4 VDC.Results:
OK - The supply voltage is 8.0 0.4 VDC at all of the digital sensor connectors. Proceed to test step 5.
Not OK - The supply voltage is not 8.0 0.4 VDC. There is an open circuit in the harness or connectors.Repair: Repair the connectors or wiring and/or replace the connectors or wiring.STOPTest Step 5. Check the Digital Sensors for Short Circuits.
Turn the battery disconnect switch to the ON position.
Turn the ECS to the STOP position. The engine should be off.Note: If the sensor is disconnected from the harness, an open circuit diagnostic code will be generated for that sensor. Troubleshoot the original code. Delete the logged diagnostic codes when you are finished.
Connect one digital sensor at a time.
Measure the voltage between the digital sensor supply P1-35 and the digital sensor return P1-29 at the ECM connector J1/P1. Repeat these steps with all of the digital sensors.
Turn the ECS to the OFF/RESET position.
Turn the battery disconnect switch to the OFF position.Expected Result:The supply voltage
