NO RESPONSE FROM CCN (CLUSTER) - START/STOP

For a complete wiring diagram, refer to the Wiring Information.

Possible Causes
(A971) (A412) FUSED B(+) CIRCUITS OPEN OR SHORTED
(Z914) GROUND CIRCUITS OPEN
(F743) IGNITION RUN START CIRCUIT OPEN OR SHORTED
(D264) AND (D265) CAN C INTERIOR BUS (125K) CIRCUITS OPEN
CLUSTER (CCN)

1. TEST FOR INTERMITTENT CONDITION

NOTE: Check for any TSB(s) related to the condition. If a TSB applies, perform the procedure outlined in the TSB before continuing.

1.	Turn the ignition on.

NOTE: Make sure the battery voltage is between 10.0 and 16.0 volts.

2.	With the scan tool, read the module status.

NOTE: Check the TIPM for any active CAN hardware DTCs, perform DTC before proceeding.

Does the scan tool indicate that the module is active on the bus?

Yes

The no response condition is not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.

2. CHECK THE (A971) AND (A412) FUSED B(+) CIRCUITS FOR AN OPEN OR SHORT

1.	Turn the ignition off.

2.	Disconnect the Cluster C1, C2 and C3 harness connectors.

3.	Using a 12-volt test light connected to ground, check the (A971) and (A412) Fused B(+) circuits.

Does the test light illuminate brightly for each circuit?

Yes

Go To 3

Repair the open or short in the (A971) or (A412) Fused B(+) circuit.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

3. CHECK THE (Z914) GROUND CIRCUIT FOR AN OPEN

1.	Using a 12-volt test light connected to 12-volts, check each (Z914) Ground circuit.

Does the test light illuminate brightly for each circuit?

Yes

Go To 4

Repair the open in the (Z914) Ground circuit.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

4. CHECK THE (F743) IGNITION RUN START CIRCUIT FOR AN OPEN OR SHORT

1.	Turn the ignition on.

2.	Using a 12-volt test light connected to ground, check the (F743) Ignition Run Start circuit.

Does the test light illuminate brightly?

Yes

Go To 5

Repair the open or short in the (F743) Ignition Run Start circuit.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

5. CHECK THE (D265) OR (D264) CAN C INTERIOR BUS (125K) CIRCUIT FOR AN OPEN

1.	Measure the resistance of the (D264) CAN C Interior Bus (-) (125K) circuit between the TIPM C7 harness connector and the Cluster C2 harness connector.

2.	Measure the resistance of the (D265) CAN C Interior Bus (+) (125K) circuit between the TIPM C7 harness connector and the Cluster C2 harness connector.

Are the resistances below 5.0 Ohms?

Yes

Replace the Cluster in accordance with the Service Information.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).

Repair the open in the (D265) or (D264) CAN C Interior Bus (125K) circuit. Inspect the connector for damage.
Perform the BODY VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Totally Integrated Power (TIPM) - Standard Procedure).
