P2 ECM connectorTest Step 1. Inspect Electrical Connectors and Wiring
Electrical shock hazard. The electronic unit injector system uses 90-120 volts.
Turn the key switch to the OFF position. A strong electrical shock hazard is present if the key switch is not turned OFF.
Thoroughly inspect the J2/P2 ECM connector and the J300/P300 valve cover connector. Refer to Troubleshooting, "Electrical Connectors - Inspect" for details.
Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector and the J300/P300 valve cover connector that are associated with injector solenoids.
Check the ECM connector (allen head screw) for the proper torque of 6.0 N m (55 lb in).
Check the J300/P300 valve cover connector in order to ensure the proper mating of the connector.
Check the harness and wiring for abrasion and for pinch points from the injectors to the ECM.Expected Result:All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion or of pinch points.Results:
OK - Proceed to Test Step 2.
Not OK - Repair: Perform the following repair:Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.STOPTest Step 2. Check for Logged Diagnostic Codes
Connect the electronic service tool to the data link connector.
Turn the key switch to the ON position.
Check for logged diagnostic codes on the electronic service tool.Expected Result:One or more of the listed codes have been logged:
1-11 Cylinder #1 Injector current fault
2-11 Cylinder #2 Injector current fault
3-11 Cylinder #3 Injector current fault
4-11 Cylinder #4 Injector current fault
5-11 Cylinder #5 Injector current fault
6-11 Cylinder #6 Injector current faultResults:
Yes - Proceed to Test Step 4.
No - Proceed to Test Step 3.Test Step 3. Perform the "Cylinder Cutout Test"
Connect the electronic service tool to the data link connector.
When possible, put the truck on a dynamometer.
Start the engine.
Allow the engine to warm up to normal operating temperature 77 °C (171 °F).
After the engine is warmed to operating temperature, access the "Cylinder Cutout Test" by accessing the following display screens in order:
"Diagnostics"
"Diagnostic Tests"
"Cylinder Cutout Test"
Enable the cooling fan, if the fan is not controlled by the ECM. If the ECM controls the cooling fan, the cooling fan will start automatically when the test begins.
Shut off all parasitic loads such as the air conditioning and the air compressors which could affect the results of the test.
Cut out each cylinder and watch the "Fuel Position" of all of the other cylinders.
Verify that cutting out a specific cylinder causes only a slight change to the fuel position of the other cylinders in comparison to the change to the fuel position that occurs when other cylinders are cut out. If a cylinder is cut out and only a slight change occurs to the fuel position of the other cylinders, a mechanical problem with the injector or a mechanical problem with the cylinder may exist.
After the test is finished, use the electronic service tool to check for active diagnostic codes or for logged diagnostic codes that are new.Expected Result:An active diagnostic code for a cylinder fault results from running the "Cylinder Cutout Test".Results:
Yes - Proceed to Test Step 4.
No - Perform the following repair:Repair: If a cylinder is cut out and only a slight change occurs to the fuel position of the other cylinders, a mechanical problem with the injector or a mechanical problem with the cylinder may exist. If the engine is misfiring or if the engine has low power, refer to Troubleshooting, "Engine Misfires, Runs Rough or Is Unstable" and Troubleshooting, "Low Power/Poor or No Response to Throttle". If a diagnostic code for a cylinder fault results from running the "Cylinder Cutout Test", proceed to Test Step 4.Test Step 4. Perform the "Injector Solenoid Test"
Start the engine.
Allow the engine to warm up to 77 °C (171 °F) which is the normal operating temperature.
Turn the key switch to the OFF position.
Connect the electronic service tool to the data link connector.
Turn the key switch to the ON position.
After the engine is warmed to operating temperature, access the "Injector Solenoid Test" by accessing the following display screens in order:
"Diagnostics"
"Diagnostic Tests"
"Injector Solenoid Test"
Activate the test.Note: Do not confuse the "Injector Solenoid Test" with the "Cylinder Cutout Test". The "Cylinder Cutout Test" is used to shut off fuel to a specific cylinder while the engine is running. The "Injector Solenoid Test" is used in order to actuate the injector solenoids. This allows the click of the injector solenoids to be heard when the engine is not running in order to determine that the circuit is functioning properly.
As each solenoid is energized by the ECM an audible click can be heard at the valve cover. A black square will appear over the cylinder number when the cylinder is being fired.
Perform the "Injector Solenoid Test" at least two times.Expected Result:All cylinders indicate "OK".Results:
Yes - There is not an electronic problem with the injectors at this time.STOP
No - The electronic service tool displays "SHORT" for any cylinder. Proceed to Test Step 5.
No - The electronic service tool displays "OPEN" for any cylinder. Proceed to Test Step 6.Test Step 5. Check the Harness from the ECM to the Valve Cover for Short Circuits
