TEST ACTION APPLICABILITY
5 Turn the ignition off to the lock position.
Disconnect the PCM harness connector.
Remove the Transmission Control Relay.
Note: Check connectors - Clean/repair as necessary.
Connect a jumper wire between Fused B+ circuit and Transmission Control Relay
Output circuit in the Transmission Relay connector.
Ignition on, engine not running.
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.
Using a 12-volt test light connected to ground, check the Fused B+ circuit in the
appropriate terminal of special tool #8815.
NOTE: The Test light must illuminate brightly. Compare the brightness to
that of a direct connection to the battery.
Does the test light illuminate brightly?
All
Yes → Go To 6
No → Repair the Fused B+Circuit circuit for an openor high resistance.
Perform 41TE (NGC) TRANSMISSION VERIFICATION TEST -
VER 1.

MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Connect a jumper wire between Fused B+circuit and the Transmission Control Relay
Output circuit.
Ignition on, engine not running.
Using a 12-volt test light connected to ground, check both Transmission Control
Relay Output circuits in the appropriate terminal of special tool #8815.
NOTE: The test light must illuminate brightly. Compare the brightness to
that of a direct connection to the battery.
Does the test light illuminate brightly?
All
Yes → Go To 7
