B159F

NAVIGATION: NAVIGATION SYSTEM (w/ USB Audio System): B1561, B159F: XM Tuner Disconnected (Command Line)
B159F - No Response from XM Tuner

DESCRIPTION

The navigation receiver assembly and stereo component tuner assembly are connected by the AVC-LAN communication line.

When an AVC-LAN communication error occurs between the navigation receiver assembly and stereo component tuner assembly, this DTC will be stored.

HINT
* *: Even if no fault is present, this DTC may be stored depending on the battery condition or engine start voltage.
* The navigation receiver assembly is the master unit.

INSPECTION PROCEDURE

NOTICE:
* After replacing the stereo component tuner assembly of vehicles subscribed to pay-type satellite radio broadcasts, registration of the XM radio ID is necessary.
* Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

1. CHECK OPTIONAL COMPONENTS (INCLUDING ASSOCIATED WIRING)

(a) Check for optional components

(1) Check that optional components (including associated wiring) which generate radio waves are not installed.

Result

HINT
* Electrical noise from radio waves generated by optional components or the wiring for those components may affect AVC-LAN communication.
* This DTC may be stored when an AVC-LAN communication error occurs due to electrical noise.

B -- CHECK FOR DTC
A -- Continue to next step.

2. REMOVE OPTIONAL COMPONENTS (INCLUDING ASSOCIATED WIRING)

(a) Remove optional components (including associated wiring).

NOTICE:
Do not remove optional components or associated wiring without the permission of the customer.

NEXT -- Continue to next step.

3. CHECK FOR DTC

(a) Clear the DTCs Navigation System (w/ USB Audio System).

(b) Check for DTCs and check if the same trouble occurs again.

OK:

No DTCs are output.

NG -- CHECK HARNESS AND CONNECTOR (STEREO COMPONENT TUNER POWER SOURCE)

OK -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting

4. CHECK HARNESS AND CONNECTOR (STEREO COMPONENT TUNER POWER SOURCE)

(a) Disconnect the K27 stereo component tuner assembly connectors.

(b) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

5. CHECK HARNESS AND CONNECTOR (STEREO COMPONENT TUNER - MULTI-MEDIA INTERFACE ECU)

(a) Disconnect the K27 stereo component tuner assembly connector.

(b) Disconnect the J108 multi-media interface ECU connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

6. CHECK HARNESS AND CONNECTOR (NAVIGATION RECEIVER - MULTI-MEDIA INTERFACE ECU)

(a) Disconnect the K8 navigation receiver assembly connector.

(b) Disconnect the J107 multi-media interface ECU connector.

(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

7. REPLACE STEREO COMPONENT TUNER ASSEMBLY

(a) Temporarily replace the stereo component tuner assembly with new or normally one Removal.

(b) Clear the DTCs Navigation System (w/ USB Audio System).

(c) Recheck for DTCs and check if the same trouble occurs again.

OK:

No DTCs are output.

NG -- REPLACE MULTI-MEDIA INTERFACE ECU

OK -- END (STEREO COMPONENT TUNER ASSEMBLY IS FAULTY)

8. REPLACE MULTI-MEDIA INTERFACE ECU

(a) Temporarily replace the multi-media interface ECU with new or normally one Removal.

(b) Clear the DTCs Navigation System (w/ USB Audio System).

(c) Recheck for DTCs and check if the same trouble occurs again.

OK:

No DTCs are output.

NG -- REPLACE NAVIGATION RECEIVER ASSEMBLY Removal

OK -- END (MULTI-MEDIA INTERFACE ECU IS FAULTY)
