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 CAN C Diagnostic circuits, diagnose and
repair the error message 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 inoperative
(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 connectors
for broken, bent, pushed out, and corroded terminals.
No
>> Go To 2
2.
FUSED B (+) CIRCUITS 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 all Fused B (+)
circuits.
Does the test light illuminate brightly for each circuit?
Yes
>> Go To 3
No
>> Repair the Fused B(+) circuit that did not light the test light for an open or short.

3.
FUSED IGNITION SWITCH OUTPUT CIRCUITS OPEN AT TIPM
Turn the ignition on.
Using a 12-volt test light connected to ground, and using the wiring diagram as a guide, check each Fused Ignition
Switch Output circuit.
Does the test light illuminate brightly for each circuit?
Yes
>> Go To 4
No
>> Repair the Fused Ignition Switch Output circuit that did not light the test light for an open.
Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES - STANDARD PROCEDURE)
4.
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.
Does the test light illuminate brightly on each circuit?
Yes
>> Go To 5
No
>> Repair the ground circuit that did not light the test light for an open.
Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES - STANDARD PROCEDURE)
5.
CHECK FOR (D52) CAN C DIAGNOSTIC (+) CIRCUIT OPEN AT DLC
Disconnect the TIPM C6 harness connector.
Measure the resistance on the D52 CAN C Diagnostic (+) circuit
between the TIPM C6 harness connector and the DLC
Is the resistance above 10 ohms?
Yes
>> Repair the D52 CAN C Diagnostic (+) circuit for an open.
Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 -

STANDARD PROCEDURE)
No

6.
CHECK FOR (D51) CAN C DIAGNOSTIC (-) CIRCUIT OPEN AT DLC
Measure the resistance on the D51 CAN C Diagnostic (-) circuit
between the TIPM C6 harness connector and the DLC
Is the resistance above 10 ohms?
Yes
>> Repair the D51 CAN C Diagnostic (-) circuit for an open.
Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 -
ELECTRICAL/ELECTRONIC CONTROL MODULES -
STANDARD PROCEDURE)
No
>> Go To 7
7.
CHECK FOR CAN C DIAGNOSTIC CIRCUITS SHORTED TOGETHER
Measure the resistance between the (D52) CAN C Diagnostic (+) circuit
and the (D51) CAN C Diagnostic (-) circuit at the TIPM C6 harness connector.
Is the resistance below 100. 0 ohms?
Yes
>> Repair the (D52) CAN C Diagnostic (+) circuit for a short to
the (D51) CAN C Diagnostic (-) circuit.
Perform 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.
