INSPECTION PROCEDURE

NOTICE:
* Inspect the fuses for circuits related to this system before performing the following inspection procedure.
* After replacing the radio and display receiver assembly of vehicles subscribed to pay-type satellite radio broadcasts, XM radio ID registration is necessary (w/ SDARS System).

PROCEDURE

1. CHECK DTC

(a) If DTC B15C3 is output, perform the troubleshooting of DTC B15C3 first.

Result:

B -- GO TO DTC "B15C3" IN DIAGNOSTIC TROUBLE CODE CHART
A -- Continue to next step.

2. CHECK OPTIONAL COMPONENTS (INCLUDING ASSOCIATED WIRING)

(a) 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 DTC
A -- Continue to next step.

3. 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.

4. CHECK DTC

(a) Clear the DTCs Audio And Visual System (without Intuitive Parking Assist System).

(b) Recheck for DTCs and check if the same DTC is output again.

OK:

No DTCs are output.

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

OK -- END

5. CHECK HARNESS AND CONNECTOR (STEREO COMPONENT AMPLIFIER ASSEMBLY POWER SOURCE)

(a) Disconnect the stereo component amplifier 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.

6. CHECK HARNESS AND CONNECTOR (RADIO AND DISPLAY RECEIVER ASSEMBLY - STEREO COMPONENT AMPLIFIER ASSEMBLY)

(a) Disconnect the radio and display receiver assembly connector.

(b) Disconnect the stereo component amplifier assembly 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 AMPLIFIER ASSEMBLY

(a) Replace the stereo component amplifier assembly Removal.

(b) Clear the DTCs Audio And Visual System (without Intuitive Parking Assist System).

(c) Recheck for DTCs and check if the same DTC is output again.

OK:

No DTCs are output.

NG -- REPLACE RADIO AND DISPLAY RECEIVER ASSEMBLY Removal

OK -- END
