SKREEM TERMINATION

With the ignition off.

Measure the resistance of the SKREEM CAN C BUS termination by
backprobing between the CAN C BUS (+) circuit and the CAN C BUS
(-) circuit at the SKREEM C2 harness connector.

Is the resistance between 110 and 130 ohms?

Yes

>> Go To 6

No

>> Replace the Sentry Key Remote Entry Module. (Refer to 8

- ELECTRICAL/ELECTRONIC CONTROL MODULES/EN-
TRY MODULE - REMOVAL).

Perform POWERTRAIN VERIFICATION TEST - VER 2.

6.

CAN C BUS (-) CIRCUIT OPEN

With the ignition off.

Disconnect the SKREEM C2 harness connector.

Note: Check connectors — Clean/repair as necessary.
Measure the resistance of the CAN C BUS (-) circuit from the
SKREEM C2 harness connector to the PCM C4 harness connector.

Is the resistance below 5.0 ohms?

Yes

>> Go To 7

No

>> Repair the CAN C BUS (-) circuit for an open.

Perform POWERTRAIN VERIFICATION TEST - VER 2.

CAN C BUS (+) CIRCUIT OPEN

With the ignition off.

Measure the resistance of the CAN C BUS (+) circuit from the PCM
C4 harness connector to the SKREEM C2 harness connector.

Is the resistance below 5.0 ohms?

Yes

>> Go To 8

No

>> Repair the CAN C BUS (+) circuit for an open.

Perform POWERTRAIN VERIFICATION TEST - VER 2.

8.

CAN C BUS (+) CIRCUIT SHORT TO VOLTAGE

Turn the ignition on.

Measure the voltage of the CAN C BUS (+) circuit at the PCM C4 har-
ness connector.

Is the voltage below 1.0 volt?

Yes

>> Go To 9

No

>> Repair the CAN C BUS (+) circuit for a short to voltage.

Perform POWERTRAIN VERIFICATION TEST - VER 2.

CAN C BUS (-) CIRCUIT SHORT TO VOLTAGE

With the ignition on.

Measure the voltage of the CAN C BUS (-) circuit at the PCM C4 har-
ness connector.

Is the voltage below 1.0 volt?

Yes

>> Go To 10

No

>> Repair the CAN C BUS (-) circuit for a short to voltage.

Perform POWERTRAIN VERIFICATION TEST - VER 2.

10.

CAN C BUS (-) CIRCUIT SHORT TO GROUND

Turn the ignition off.

Measure the resistance between ground and the CAN C BUS (-) cir-
cuit.

Is the resistance above 100 kohms?

Yes

>> Repair the CAN C BUS (+) circuit for a short to ground.

Perform POWERTRAIN VERIFICATION TEST - VER 2.

No

>> Repair the CAN C BUS (-) circuit for a short to ground.

Perform POWERTRAIN VERIFICATION TEST - VER 2.

11.

CAN C BUS (-) CIRCUIT OPEN FROM TCM TO PCM

With the ignition off.

Disconnect the TCM C3 harness connector.

Note: Check connectors — Clean/repair as necessary.
Measure the resistance of the CAN C BUS (-) circuit from the TCM C3
harness connector to the PCM C4 harness connector.

Is the resistance below 5.0 ohms?

Yes

>> Repair the CAN C BUS (+) circuit for an open between the

PCM C4 harness and the TCM C3 harness connector.

Perform POWERTRAIN VERIFICATION TEST - VER 2.

No

>> Repair the CAN C BUS (-) circuit for an open between the

PCM C4 harness and the TCM C3 harness connector.

Perform POWERTRAIN VERIFICATION TEST - VER 2.

INTERMITTENT WIRING AND CONNECTORS

The conditions necessary to set this DTC are not present at this time.

Note: Check connectors — Clean/repair as necessary. Poor pin to terminal connections can set DTCs.

Note: Check for any Technical Service Bulletins that may apply.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors specific to this DTC. Wiggle the
wires while checking for shorts and/or open circuits.

Were there any problems found?

Yes

>> Repair as necessary.

Perform POWERTRAIN VERIFICATION TEST VER.

No

>> The condition that caused this DTC to set is currently not present. Inspect the related wiring harness for

a possible intermittent condition.
