DESCRIPTION

The display and navigation module display and navigation module board are connected by the IEEE cable.

When an IEEE communication error occurs between the display and navigation module display and navigation module board, 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 display and navigation module display is the master unit.

WIRING DIAGRAM

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 IEEE communication.
* This DTC may be stored when an IEEE communication error occurs due to electrical noise.

B -- CHECK 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 DTC

(a) Clear the DTCs Navigation System (for DVD).

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

OK:

No DTCs are output.

NG -- CHECK HARNESS AND CONNECTOR (NAVIGATION MODULE BOARD POWER SOURCE)

OK -- END

4. CHECK HARNESS AND CONNECTOR (NAVIGATION MODULE BOARD POWER SOURCE)

(a) Disconnect the z4 navigation module board connector.

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

Standard Resistance:

NG -- CHECK HARNESS AND CONNECTOR
OK -- Continue to next step.

5. CHECK IEEE CABLE CONNECTOR

(a) Check for the IEEE cable connector.

(1) Check if the IEEE cable connectors between the navigation module board and the display and navigation module display have any connection problems Electronic Circuit Inspection Procedure.

(b) Check that the screen display is normal.

OK:

Screen display is normal.

NG -- REPLACE IEEE CABLE

OK -- END

6. REPLACE IEEE CABLE

(a) Replace the IEEE cable between the navigation module board and the display and navigation module display.

(b) Check that the screen display is normal.

OK:

Screen display is normal.

NG -- REPLACE NAVIGATION MODULE BOARD

OK -- END

7. REPLACE NAVIGATION MODULE BOARD

(a) Replace the navigation module board Removal.

(b) Clear the DTCs Navigation System (for DVD).

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

OK:

No DTCs are output.

NG -- REPLACE DISPLAY AND NAVIGATION MODULE DISPLAY Removal

OK -- END

8. CHECK HARNESS AND CONNECTOR

(a) Disconnect the z5 display and navigation module display connector.

(b) Disconnect the z4 navigation module board connector.

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

Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE DISPLAY AND NAVIGATION MODULE DISPLAY Removal
