Service
1.

Upload GFF paperless log showing communication DTCs as described in the complaint.

2.

Overlay new CAN twisted pair wiring behind the dashboard, between the two 46-pin CAN
disconnect plugs (T46a/1H T46b/1H and T46a/1L T46b/1L).
Tip: Protect twisted pair with loom and abrasion resistant cloth. Beware of any moving parts
behind dash panel that may chafe the wiring overlay.

instrument cluster will aid in secure wire routing.
