*NO RESPONSE FROM SATELLITE RECEIVER (SDAR)





For a complete wiring diagram Consult Diagrams/Electrical.





Diagnostic Test

1. ESTABLISH COMMUNICATION WITH RADIO
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 communicate with the Radio?

Yes

- Go To 2

No

- Perform the appropriate no response test. Refer to the No Response tests Communications - Verbose Codes

2. VISUALLY INSPECT THE RADIO AND SATELLITE RECEIVER CONNECTORS
Turn the ignition off.
Disconnect the Radio C2 harness connector.
Disconnect the Satellite Receiver harness connector.
Visually inspect the connectors for damage and pushed out pins.
Was any damage found?

Yes

- Repair as necessary.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Go To 3

3. (Z966) GROUND CIRCUIT OPEN




Reconnect the Radio C2 harness connector.
Using a 12-volt test light connected to 12-volts, probe the (Z966) ground circuit at the Satellite Receiver harness connector.
Does the test light illuminate brightly?

Yes

- Go To 4

No

- Repair the (Z966) Ground circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

4. (X211) IGNITION RUN/ACC SIGNAL CIRCUIT OPEN




Turn the ignition on.
Using a 12-volt test light connected to ground, probe the (X211) Ignition Run/Acc Signal circuit.
Does the test light illuminate brightly?

Yes

- Go To 5

No

- Repair the (X112) Ignition Run/Acc Signal circuit for an open. If ok, replace the Radio.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

5. (X160) FUSED B(+) CIRCUIT OPEN




Using a 12-volt test light connected to ground, probe the (X160) Fused B(+) circuit.
Does the test light illuminate brightly?

Yes

- Go To 6

No

- Repair the (X160) Fused B(+) circuit for an open. If ok, replace the Radio.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

6. (D25) PCI BUS CIRCUIT OPEN




Turn the ignition off.
Disconnect the Radio C2 harness connector.
Measure the resistance of the (D25) PCI Bus circuit between either the Radio C2 harness connector and the Satellite Receiver harness connector.
Is the resistance below 5.0 ohms?

Yes

- Replace the Satellite Receiver.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.

No

- Repair the (D25) PCI Bus circuit for an open.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test.
