*NO RESPONSE FROM CCN (CLUSTER)

For a complete wiring diagram Refer to Section 8W.

Possible Causes

(A418) (A412) FUSED B(+) CIRCUITS OPEN OR SHORTED

(Z936) (Z937) GROUND CIRCUITS OPEN

(F202) IGNITION SWITCH OUTPUT CIRCUIT OPEN OR SHORTED

(D55) AND (D54) CAN B BUS CIRCUITS OPEN

CLUSTER (CCN)

Diagnostic Test

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.

Turn the ignition on.

NOTE: Ensure the IOD fuse is installed and battery voltage is between 10.0 and 16.0 volts.

With the scan tool, select ECU View.

NOTE: A red X will be next to the module that is not communicating, indicating that the module is not active on the Bus network. A green check indicates that the module is active on the Bus network.

Does the scan tool display a red X next to the module?

Yes

Go To 2

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.

2. (A418) (A412) FUSED B(+) CIRCUIT OPEN OR SHORTED

Turn the ignition off.
Disconnect all Cluster harness connectors.
Using a 12-volt test light connected to ground, check each (A418) and (A412) Fused B(+) circuit.

Does the test light illuminate brightly for each circuit?

Yes

Go To 3

Repair the Fused B(+) circuit for an open or short.
Perform the BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

3. (Z936) (Z937) GROUND CIRCUITS OPEN

Using a 12-volt test light connected to 12-volts, check each (Z936) and (Z937) ground circuit.

Does the test light illuminate brightly for each circuit?

Yes

Go To 4

Repair the (Z936) or (Z937) ground circuit for an open.
Perform the BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

4. (F202) IGNITION SWITCH OUTPUT CIRCUIT OPEN OR SHORTED

Turn the ignition on.
Using a 12-volt test light connected to ground, check the (F202) Ignition Switch Output circuit.

Does the test light illuminate brightly?

Yes

Go To 5

Repair the (F202) Ignition Switch Output circuit for an open or short.
Perform the BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

5. (D55) AND (D54) CAN B BUS CIRCUITS OPEN

NOTE: One open circuit will not cause this condition.

Measure the voltage between the (D54) CAN B Bus (-) circuit and ground.
Measure the voltage between the (D55) CAN B Bus (+) circuit and ground.

Is there any voltage present on either circuit?

Yes

Replace the Cluster in accordance with the service information.

Perform the BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).

Repair the (D55) and (D54) CAN B Bus circuits for an open. Inspect the connector for damage.
Perform the BODY VERIFICATION TEST – VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
