TEST
ACTION
APPLICABILITY
1
NOTE: Record the Freeze Frame Information that set along with the DTC.
Turn the ignition on.
With the DRBIII
t, read DTC’s.
Is the Good Trip displayed and equal to zero?
All
Yes
→ Go To 2
No
→ Refer to the INTERMITTENT CONDITION symptom in the
Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
2
Turn the ignition off.
Disconnect the Fuel Injector harness connector.
Measure the resistance of the Fuel Injector, component side.
Is the resistance between 10 and 16 ohms?
All
Yes
→ Go To 3
No
→ Replace the Fuel Injector.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
3
Turn the ignition off.
Disconnect the Fuel Injector harness connector.
Remove the ASD Relay from the IPM.
Turn the ignition on.
Jumper the Fused B+ circuit and the ASD Relay Output circuit in the IPM.
Using a 12-volt test light connected to ground, probe the (K342) ASD Relay Output
circuit.
Does the test light illuminate brightly?
All
Yes
→ Go To 4
No
→ Repair the open in the (K342) ASD Relay Output circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

4
Turn the ignition off.
Disconnect the Fuel Injector harness connector.
Disconnect the PCM harness connector.
Measure the resistance of the Fuel Injector driver circuit between the Fuel Injector
harness connector and the PCM harness connector.
Is the resistance below 5.0 ohms?
All
Yes
→ Go To 5
No
→ Repair the open in the Fuel Injector driver circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
5
Turn the ignition off.
Disconnect the Fuel Injector harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the Fuel Injector driver circuit in the
Fuel Injector harness connector.
Is the resistance below 100k ohms?
All
Yes
→ Repair the open in the Fuel Injector driver circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Go To 6

NOTE: Before Continuing: Disconnect the PCM harness connector and
check the related wiring terminals for corrosion, damage or terminal push
out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay
particular attention to all Power and Ground circuits.
If there are no possible causes remaining, view repair.
All

Replace and program the Powertrain Control Module in accor-
dance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
