01 REPLACEMENT OF COMPONENTS ON THE CAN NETWORK AND CENTRAL GATEWAY CONTROL MODULE LAN REGISTRATION

Techline recommends that if any component on the CAN network attached to the Central Gateway Control Module (CGW) is replaced, that the CGW be re-registered so it can properly identify and function with other modules.

An example Techline has identified is if the DCM is replaced for a fault code, the remote services associated with the Gen 2 Telematics system may operate erratically or be inoperative. The DCM provides the command to the network through the CGW, and in turn, the CGW distributes the command. If the CGW is not registered to the new device, the command may not be completed.

This situation could happen with any device on the network, including but not limited to the Cockpit Control Unit (CCU), Cockpit Information Display (CID), Body Integrated Unit (BIU), Engine Control Module (ECM, Air Conditioning Control Module, or Keyless Access Control Module (KACM). These devices receive and provide commands to and from the CGW.

It is best practice to perform this action before the repairs are finalized and the vehicle system in question is retested for proper operation. The re-register command can be found in the CGW Work Support using the SSM. Proper battery charge should be checked before issuing this command.

If a component is swapped for another vehicle for testing, a Recovery option is also in work support which will have you re-register the system again.

RE REGISTER LAN CONNECTION UNIT 

1. On [Start] screen, select [Diagnosis]. 
2. On [Select Vehicle] screen, input the target vehicle information and select [OK]. 
3. On [Main Menu] screen, select [Each System]. 
4. On [Select System] screen, select [Central Gateway], and then select [Next]. 
5. On [Select Function] screen, select [Work Support]. 
6. Select [Re-register LAN connection unit] on the [Work Support] screen. 

15 CHARGING CABLES AND TOUCH SCREEN CONCERNS

Please be aware that charging cables should not be routed in front of any touch device such as the Denso F10, Harman Headunits, and CP1 Cockpit Display. Routing the cables across the touch screen can cause erratic operation of the screen. This is referred to as 'ghost touch'. This is caused by an electrical pulse through the wire being interpreted as an input by the screen. This unwanted input can cause intermittent screen concerns and even unit crashing. This concern can be traced back to the first Denso F10 Units.

If faced with an intermittent screen operation concern, it is important during the customer interview process to ask where the customers phone/device is kept or mounted. Pay close attention to the windshield/dashboard area for suction cup mounting marks, magnetic mounts or weighted phone mounts. An example of an external device is typically, but not limited to; a third-party GPS, a cell phone mount, or wireless charger. These components are useful hints as too how the vehicle is being used.

Pictured to the right, is an example from Techline of a customer with a wireless charger mounted to the pocket above the Headunit. The Customer concern was intermittent no response from the touch screen and screen distortion. Not only is the charging cord across the screen but the electromagnetic effect of the wireless charger. In some vehicle this may affect speaker performance.

Pictured to the left, is an example of a phone mount and charging set up that could affect the screen responsiveness and behavior. Projection apps can be affected by this concern as well.

Finally, with the addition of CP1 to the Subaru lineup, there is a much larger screen where multiple inputs can be made. Shown to the right is an example of how a charging cord could affect the screen. This is especially noticeable in radio mode or a screen with several selections such as SXM or Navigation. This could cause a no response situation or screen distortion until the key is cycled and the cord is removed.

15 CP1 NAVIGATION SHOWS THE WRONG LOCATION

Retailers may receive vehicles with a customer complaint of the navigation showing the wrong location.

This condition may show the vehicle a few miles off from the current location, the wrong town, the wrong state, or out in open water. The following instructions will clear the condition and explain how to reset the vehicle properly. Failure to follow these steps will not resynchronize the unit and may lead to unnecessary part replacement.

Below are two examples of common wrong locations seen.
