It's a 2006 model with automatic transmission (AW50/51), diesel (eng. code: D5244T). Car was in accident - front was crushed.

So problems and symptoms:

1. hand brake on, ignition off - check engine lamp illuminates for a while.
I checked wiring from parking brake switch to DIM (dash) - no shortage. Maybe it's should be like this if there is problem with brakes? (Can't connect with dice to BCM - abs.)



2. No gear indicator lamp on dash. sometimes it appears, but then it disappears after minute. Same with odometer trip value...

I checked high speed can lines between ecm, tcm, cem modules - everything is fine. tried to disconnect plug from abs - no change.

Sometimes car starts, but the indications on dash are also sometimes working sometimes not...

If I connect Volvo dice on it - it always, every few min. drops connection with car. and no response from TCM.

Checked power supply and grounds to tcm - it's ok. Checked GSM - also all power, ground data line is ok....

Tomorrow i will continue my survey with this model. Any hint's would be appreciated.
