Troubleshooting Test Steps
Values Results
1. Check for Active Diagnostic Codes
A. Connect the electronic service tool to the diagnostic
connector.
B. Turn the keyswitch to the ON position.
C. Check for active diagnostic codes or recently logged diag-
nostic codes.
Diagnostic codes Result: No diagnostic codes are present.
Return the unit to service.
Result: One or more of the preceding diagnostic codes are
active.
Make a note of any cylinder numbers with the active diag-
nostic code. Proceed to Test Step 2.
2. Check the Injector Code on any Suspect Cylinders
A. Connect the electronic service tool to the diagnostic con-
nector. Refer to Troubleshooting, “Electronic Service Tools”.
B. Turn the keyswitch to the ON position.
C. Select the following menu options on the electronic service
tool in order to obtain the injector codes from the ECM:
· “Service”
· “Calibrations”
· “Injector Trim Calibration”
D. Make a note of the injector codes for any suspect cylinders.
Diagnostic code Result: The card that was supplied with the injector is avail-
able for the suspect cylinders.
Repair: Compare the injector code from the card with the
injector code that was recorded from the electronic service
tool for each suspect cylinder.
If the codes match, proceed to Test Step 3.
If the codes do not match, then use the electronic service
tool to input the code from the card.
Result: The card with the injector code is not available.
Proceed to Test Step 3.
3. Manually Program the Injector Code
A. Remove the valve mechanism cover. Refer to Disassembly
and Assembly, “Valve Mechanism Cover - Remove and
Install”.
B. Make a note of the injector code that is on the injector in
any suspect cylinders.
Note: Refer to Illustration 117 for the correct sequence for re-
cording the injector code.
C. Compare the injector code from the injector with the injector
code from the electronic service tool for each suspect cylinder.
Injector codes Result: The code on the injector is the same as the code in
the ECM.
Repair: The injector is incorrect for the engine. Replace the
injector with the correct injector for the engine. Refer to Dis-
assembly and Assembly, “Electronic Unit Injector - Re-
move” and refer to Disassembly and Assembly, “Electronic
Unit Injector - Install”.
Result: The code on the injector is not the same as the
code in the ECM.
Repair: Use the electronic service tool to input the correct
injector code. Refer to Troubleshooting, “Injector Code -
Calibrate” for the correct procedure.
Use the electronic service tool in order to clear all logged di-
agnostic codes and then verify that the repair eliminates the
fault.
If the procedure did not correct the issue, contact the Deal-
er Solutions Network (DSN).
