Ducati Diavel Service Manual: The hands free module

Introduction

The hands free module incorporates the control unit communicating with the other nodes on the motorcycle, the on/off button, the microswitches detecting full lock steering angle (for enabling steering lock engagement) and the steering lock.

The module is sealed and its individual components cannot be accessed for diagnosis, repair or replacement.

Wiring diagram

No wiring diagram is available for the components integrated into the hands free module. For the main electric wiring see chapter ("wiring diagram of the hands free system") of this section.

Error codes

"Hands free diagnosis" error: "steering lock": a fault has been detected in the electric steering lock system. The following icon appears on the tank dashboard:

• If the error occurred while engaging or disengaging the steering lock, check that the handlebar is fully turned to the left or right and try to engage or disengage the steering lock again.
• If the error occurred while engaging or disengaging the steering lock, check that the lock pin can move freely and is unobstructed, then try to engage or disengage the steering lock again.
• If none of the tests described above identifies the problem, replace the hands free system.

Electrical characteristics and checking component

No electrical characteristics or checking procedures are given for the hands free system as all components are integrated in the module and cannot be accessed for diagnosis, repair or replacement.

The module receives direct 12 volt battery power over pin 1 and via the main 30 a fuse.

Ground is on pin 2.

In the event of fault

In the event of any hands free system fault, the engine may switch off or engine start may not be possible.

In the event of a fault in the steering lock integrated into the hands free system occurring during either engagement or disengagement, the system will attempt to automatically retract the lock pin. If this fails, a low volume alarm signal is emitted by the hands free system.
