TEST

ACTION

APPLICABILITY

1

Perform the symptom Checking PCM Power and Ground Circuits in the Driveability
category.
NOTE: With the DRBIII

t

in the generic scan tool mode, attempt to commu-

nicate with the PCM.
NOTE: If the DRBIII

t

can communicate with the PCM in the generic scan

tool mode, it may not be necessary to perform this step.
Did the vehicle pass this test?

All

Yes

Go To

2

No

→

Repair as necessary.
Perform POWERTRAIN VERIFICATION TEST VER - 1.

2

Turn the ignition off.
Disconnect the PCM C3 harness connector.
Disconnect the DRBIII

t

from the DLC.

Measure the resistance between ground and the SCI Transmit circuit.
Is the resistance below 5.0 ohms?

All

Yes

→

Go To

3

No

→

Go To

4

3

Turn the ignition off.
Disconnect the TCM harness connector (if equipped).
NOTE: If vehicle is not equipped with a TCM, answer yes to the question.
Measure the resistance between ground and the SCI Transmit circuit.
Is the resistance below 5.0 ohms?

All

Yes

→

Repair the SCI Transmit circuit for a short to ground.
Perform POWERTRAIN VERIFICATION TEST VER - 1.

No

→

Replace the Transmission Control Module in accordance with the
service information.
