a. If SPN fault code 168 or 723/FMI any is present, service those faults first.
b. If SPN fault code 168 or 723/FMI any is NOT present, Go to step 2.
Check the warranty claim history. Check with driver. Is this the first occurrence of this fault within the last 30 days?
a. Yes; Go to step 3.
b. No; complete diagnostics, retain a log file of active fault and the measured resistance values recorded in this
procedure and contact the Customer Support Center at 800-445-1980.
Start and warm the engine until the coolant temperature is above 71°C (160°F).
Turn the engine OFF.
Disconnect the rear fuel injector harness 14-pin connector.
Inspect the rear fuel injector harness 14-pin injector connectors for bent or spread pins; inspect the connector seal for
damage (signs of water or oil intrusion).
a. If water or oil intrusion, bent or spread pins are found, repair as necessary.
b. If the connector shows no signs of damage, Go to step 7.
NOTE: DO NOT touch the metal ohmmeter leads with your hands when the measurements are made.
7. Using the appropriate chart below, measure and record the resistance values between the corresponding pins on the
valve cover side of the rear fuel injector harness listed below. Are the resistances within range?
