TEST
5 Turn the ignition off to the lock position.
Disconnect the PCM harness connector.
Remove the Transmission Control Relay from the PDC.
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
Pinout Box.
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?
Yes → Go To 6
→ Repair the Fused B+ Circuit circuit for an open or high resistance.
No
6 Turn the ignition off to the lock position.

MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Connect a jumper wire between Fused B+ circuit and the Transmission Control Relay
Output circuit in the PDC.
Ignition on, engine not running.
Using a 12-volt test light connected to ground, check both Transmission Control
Relay Output circuits in the Pinout Box.
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?
Yes → Go To 7
→ Repair the Transmission Control Relay Output circuit for an open
No
7 Turn the ignition off to the lock position.
Install a substitute Relay in place of the Transmission Control Relay.
Start the engine.
Using a voltmeter, measure the battery voltage.
With the DRBIII , monitor the Transmission Switched Battery Voltage.
Compare the DRBIII Transmission Switched Battery voltage to the actual battery
voltage.
Is the DRBIII voltage within 2.0 volts of the battery voltage?
Yes → Replace the Transmission Control Relay.
→ Go To 8
No
