B1563 - Remote Touch Disconnected
B1596 - No Response from Remote Touch

DESCRIPTION

The display and navigation module display and remote touch (remote operation board) are connected by the MOST communication line.

When a MOST communication error occurs between the display and navigation module display and remote touch (remote operation board) , these DTCs will be stored.





HINT
* *1: 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

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 MOST communication.
* This DTC may be stored when a MOST 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).
