Navigation System (for DVD)

NAVIGATION: NAVIGATION SYSTEM (for DVD): B159E, B1568: No Response from Clock Device
B159E - No Response from Clock Device
B1568 - Clock Device Disconnected

DESCRIPTION

The display and navigation module display and clock assembly are connected by the AVC-LAN communication line.

When an AVC-LAN communication error occurs between the display and navigation module display and clock assembly, these DTCs 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.

INSPECTION PROCEDURE

NOTICE:
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.
* These DTCs may be stored when an AVC-LAN 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) Check for DTCs and check if the same DTC is output again.

OK:

No DTCs are output.

NG -- CHECK HARNESS AND CONNECTOR (CLOCK - BATTERY AND BODY GROUND)

OK -- END

4. CHECK HARNESS AND CONNECTOR (CLOCK - BATTERY AND BODY GROUND)

(a) Disconnect the L38 clock assembly connector.

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

Standard Resistance:

Text in Illustration

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

5. CHECK HARNESS AND CONNECTOR (CLOCK - DISPLAY AND NAVIGATION MODULE DISPLAY)

(a) Disconnect the L38 clock assembly connector.

(b) Disconnect the L116 display and navigation module display 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. REPLACE CLOCK ASSEMBLY

(a) Temporarily the clock assembly with new or normal functioning one 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
