Use can to monitor real gear position is in from TCM

Post by chinlin0924 » 2016 Jun 04 01:11

Hello,

Does anyone ever try to hack what TCM's current gear position is in by reading the CAN bus information from TCM for automatic car?
For example, we usually put the gear position to "D" while driving forward, but I want to know the real gear position it is in transmission control module.

I tried monitoring my car via OBD's CAN HS HI/LOW pin, but in vain. looks like it is not in the CAN network segment, maybe in another segment can network.

what I know my car's TCM is based on AIXIN TCM TF-80SC, if anyone knows what CAN data format from this, please let me know

thank you
regards,
chinlin
