TOAF Error codes - where to start looking

[AndyN01]

Hi all.

Plugged TOAF in the other day and got these codes:

C7 Lever type sensor 1 - Short circuit to batt +; Sporadic error

F4 Can-Bus 244 - Open circuit; Sporadic error

20 Logic Power loss; Sporadic error

20 Soundgenerator rear off; Short circuit to ground; Open circuit; Error Present; Sporadic error (I guess this is something to do with the tow bar wiring that was found to be missing an earth when investigated at the recent Nano).

21 HVAC Front load sensor break; Error count 1; Error present

28 Clamp R missing; Error count 1; Error not present

(SHADOW) 42 - left low beam defect; Error count 1; Error not present


The electronics side of things I'm not so good at .

If someone call tell me which ones need some investigating and where to look I'll be grateful.

Cheers.

Andy.
