Newholland t7.235 autocommand actuation timeout

[Stewart97]

I have a newholland t7.235 autocommand with the electric handbrake went to start it she wouldn't turn over you would think the battery was low tried it again and she started grand but the electric handbrake will not disengage it is showing up 12185 and 12213 there isnt a sound of the handbrake winding off.

Caused by a voltage drop. Once the tractor has warmed up enough/ recharged battery, select park and restart tractor. Usually cures ours. Failing that might need a recalibration of the handbrake

Thank you for your reply i will try this tomorrow how can the electric handbrake be recalibrated

 

[del_boy]

I think its, hold shuttle button while start engine, foot on brake, select forward, wait few seconds, select park, wait few seconds Switch off engine, release button wait for all computers to shut down then restart.
You shouldn't need to do that as your problem is caused by voltage drop.

Thanks for your reply i have tried both this morning and still no joy i can only hear the actuator leting a click but not winding off

 

[del_boy]

The click is probably the air brake solenoid releasing.
Is the manual handbrake definitely off.
There was a software update to stop the low voltage interfering with the epl, maybe yours hasn't had this. Might be a dealer job im afraid unless you have a diagnostic plug to access the h menu and delete the fault codes

Yeah i can hear a click of the air brakes but when i move the park brake i can hear the actuator letting a we click noise aswell but doesn't wind off the manual handbrake is definitely off aswell even got in underneath to see thanks

 

[del_boy]

Voltage drop was a big issue with the epl. Sounds like your gonna need a dealer with laptop im afraid

 

[Stewart97]

Just after mucking about there i have got her going park brake is winding off no problem now

Charge battery with charger or let engine run 20mins BEFORE you attempt to release park brake...
