(D64) CAN C BUS (-) CIRCUIT OPEN
Measure the resistance of the (D64) CAN C Bus (-) circuit between the
TIPM C3 harness connector and the TCM C1 harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Replace and program the Transmission Control Module in
accordance with the service information.
Perform the appropriate VERIFICATION TEST.
No
>> Repair the (D64) CAN C Bus (-) circuit for an open.
Perform the CVT VERIFICATION TEST.

Diagnostic Test
1.
TEST FOR INTERMITTENT CONDITION
Turn the ignition on.
NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.
NOTE: Ensure the scan tool is updated to the latest software.
NOTE: If the scan tool displays any error messages involving the Diagnostic CAN C circuits, diagnose and
repair the errors before proceeding. Refer to the Table of Contents.
NOTE: A loss of communication with the TIPM can cause the ECU View button on the scan tool to be inop-
erative (not highlighted).
With the scan tool, attempt to select ECU View.
Can the scan tool communicate with the TIPM?
Yes
>> The no response condition is not present at this time. Using the wiring diagram/schematic as a guide,
inspect the wiring for chafed, pierced, pinched, and partially broken wires and the wiring harness con-
nectors for broken, bent, pushed out, and corroded terminals.
No
>> Go To 2
2.
DIRECT BATTERY FEED CIRCUIT OPEN AT TIPM
Disconnect the scan tool from the DLC.
Using a 12-volt test light connected to ground, and using the wiring diagram as a guide, check the direct battery
feed circuit at the TIPM.
Does the test light illuminate brightly?
Yes
>> Go To 3
No
>> Repair the direct battery feed circuit for an open.
Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES - STANDARD PROCEDURE)
3.
GROUND CIRCUITS OPEN AT TIPM
Turn the ignition off.
Using a 12-volt test light connected to 12-volts, and using the wiring diagram as a guide, check all ground circuits
at the TIPM.
Does the test light illuminate brightly on each circuit?
Yes
>> Go To 4
No
>> Repair the ground circuit that did not light the test light for an open.
Perform the BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES - STANDARD PROCEDURE)

CHECK FOR (D72) DIAGNOSTIC CAN C (+) CIRCUIT OPEN AT DLC
Disconnect the TIPM C3 harness connector.
Measure the resistance on the (D72) Diagnostic CAN C (+) circuit
between the TIPM C3 harness connector and the DLC.
Is the resistance above 10.0 ohms?
Yes
>> Repair the (D72) Diagnostic CAN C (+) circuit for an open.
Perform the BODY VERIFICATION TEST - VER 1. (Refer to
8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE)
No
>> Go To 5
5.
CHECK FOR (D71) DIAGNOSTIC CAN C (-) CIRCUIT OPEN AT DLC
Measure the resistance on the (D71) Diagnostic CAN C (-) circuit
between the TIPM C3 harness connector and the DLC.
Is the resistance above 10.0 ohms?
Yes
>> Repair the (D71) Diagnostic CAN C (-) circuit for an open.
Perform the BODY VERIFICATION TEST - VER 1. (Refer to
8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE)
No

CHECK FOR DIAGNOSTIC CAN C CIRCUITS SHORTED TOGETHER
Measure the resistance between the (D72) Diagnostic CAN C (+) circuit
and the (D71) Diagnostic CAN C (-) circuit at the TIPM C3 harness con-
nector.
Is the resistance below 100.0 ohms?
Yes
>> Repair the (D72) Diagnostic CAN C (+) circuit for a short to
the (D71) Diagnostic CAN C (-) circuit.
Perform the BODY VERIFICATION TEST – VER 1. (Refer
to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE).
No
>> Replace the Totally Integrated Power Module in accordance
with the service information.
Perform the BODY VERIFICATION TEST – VER 1. (Refer
to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE).
