Cabin Compartment Node (CCN)

B2563-POWER SLIDING DOOR SWITCH CIRCUIT HIGH





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

- When Monitored:
With the ignition on.

- Set Condition:
When the Cluster senses voltage over 4.95 volts (switch connected) on the (G23) Sliding Doors Overhead Switch MUX circuit for longer than 10 seconds, this code will set.





Diagnostic Test

1. CHECK FOR AN ACTIVE DIAGNOSTIC TROUBLE CODE (DTC)
1. Turn the ignition on.
2. With the scan tool, read DTCs.

Does the scan tool display this DTC as active?

Yes

- Go To 2

No

- Test complete, the condition or conditions that originally set this DTC are 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.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK (G23) SLIDING DOORS OVERHEAD SWITCH MUX CIRCUIT FOR A SHORT TO VOLTAGE




1. Turn the ignition off.
2. Disconnect the Switch Bank 2 (Overhead Console) harness connector.
3. Turn the ignition on.
4. Measure the voltage between ground and the (G23) Sliding Doors Overhead Switch MUX circuit in the Switch Bank 2 harness connector.

Is the voltage above 5.0 volts?

No

- Go To 3

Yes

- Go To 5

3. CHECK THE (Z905) GROUND CIRCUITS FOR AN OPEN




1. Turn the ignition off.
2. Using a 12-volt test light connected to 12-volts, check the (Z905) Ground circuits in the Switch Bank 2 harness connector.

Does the test light illuminate brightly?

No

- Repair the (Z905) Ground circuits for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Go To 4

4. CHECK THE (G23) SLIDING DOORS OVERHEAD SWITCH MUX CIRCUIT FOR AN OPEN




1. Turn the ignition off.
2. Disconnect the Cluster C1 harness connector.
3. Measure the resistance of the (G23) Sliding Doors Overhead Switch MUX circuit between the Switch Bank 2 harness connector and the Cluster C1 harness connector.

Is the resistance below 5.0 ohms?

No

- Repair the (G23) Sliding Doors Overhead Switch MUX circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

Yes

- Replace the Switch Bank.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. CHECK THE (G23) SLIDING DOORS OVERHEAD SWITCH MUX CIRCUIT FOR A SHORT TO VOLTAGE




1. Turn the ignition off.
2. Disconnect the Cluster C1 harness connector.
3. Turn the ignition on.
4. Measure the voltage between ground and the (G23) Sliding Doors Overhead Switch MUX circuit in the Switch Bank 2 harness connector.

Is there any voltage present?

Yes

- Repair the (G23) Sliding Doors Overhead Switch MUX circuit for a short to voltage.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Cluster.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
