5
Turn the ignition off.
Disconnect the C2 PCM harness connector.
Measure the resistance between the Ignition Coil Driver circuit and ground.
Is the resistance below 100 ohms?
All
Yes
→ Repair the short to ground in the Ignition Coil Driver circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Note: Before continuing, check the PCM harness connector ter-
minals for corrosion, damage, or terminal push out. Repair as
necessary. Replace and program the Powertrain Control Module
in accordance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
6
Turn the ignition off.
Disconnect the C2 PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the Ignition Coil Driver circuit from the Coil Rail harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes
→ Note: Before continuing, check the PCM harness connector ter-
minals for corrosion, damage, or terminal push out. Repair as
necessary. Replace and program the Powertrain Control Module
in accordance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Repair the open in the Ignition Coil Driver circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
