NOTE: Check all PCM powers and grounds before continuing.
NOTE: Ensure that SKIS is operating properly. Check the SKIM for DTC. If
a SKIM DTC(s) is present diagnose them first before continuing.
WARNING: MAKE SURE THE BATTERY IS DISCONNECTED, THEN WAIT
TWO MINUTES BEFORE PROCEEDING.
Turn the engine over by hand to ensure the engine is not seized.
Is the engine able to turn over?
All
Yes
→ Go To 2
No
→ Repair the mechanical condition preventing the starter motor
from cranking.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
2
Turn the ignition off.
Disconnect the PCM harness connectors.
Move the Gear selector through all gear positions, from Park to 1st and back.
While moving the gear selector through each gear, measure the resistance between
ground and the P/N Position Switch Sense circuit.
Did the resistance change from above 10.0 ohms to below 10.0 ohms?
All
Yes
→ Go To 3
No
→ Replace the Transmission Range Sensor.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
3
Turn the ignition off.
Check the Battery Cables for high resistance using the service information proce-
dure.
Did either Battery Cable have a voltage drop greater than 0.2 volt?
All
Yes
→ Repair the Battery circuit for high resistance.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
No
→ Go To 4

4
Turn the ignition off.
Disconnect the 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.
Turn the ignition to the Start position.
Using a 12-volt test light connected to ground, probe the Fused Ignition Switch
Output (Start) circuit in the appropriate terminal of special tool #8815.
Does the test light illuminate brightly?
All
Yes
→ Go To 5
No
→ Repair the Fused Ignition Switch (Start) circuit for an open or
high resistance.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
5
Turn ignition off.
Remove the Starter Relay from PDC.
WARNING: The Parking Brake must be on and the Transmission must be in
park for a vehicle equipped with an automatic transmission, manual
Transmission must be in neutral.
Warning: The engine may be cranked in the next step. Keep away from
moving engine parts.
Briefly connect a jumper wire between Starter Relay B+ circuit and the Starter Relay
Output Circuits.
Did the Starter Motor crank the engine?
All
Yes
→ Go To 6
No
→ Go To 9
6
Turn the ignition off.
Remove the Starter Relay from the PDC.
Turn the ignition on.
Using a 12-volt test light, probe the Ignition Switch Output circuit in the Starter
Relay connector.
