Hello,
Please Help
Aafter the truck was in for two hours in the rain refused to work. There was a red display and T334_T335 error.
It has been tested :
Emergency stop switch S1,
Key switch 7S1 ,
Fuse all
Fans 9M2 and 9M3
Main contactor K1 - power to the coil is 11V, 48V must.
output voltage (X13: 1 , X13: 3) with the device electronic control unit assy. LDC- 60/11 , to the main contactor - 11V.
Opened electronic control unit assy. LDC- 06 / 11 , no signs of water ingress.
What could be the problem???
Showing items 1 - 3 of 3 results.
Generally these codes apply to the voltages on power modules.
334 - With main contactor activated, capacitor voltage at power module 2A1 too low.
335 - With main contactor activated, capacitor voltage at power module 1A1 too low.
These are the big, heavy modules on the drive axle. Extremely expensive. The output voltage should be ~ 13V.
Anyway, before panicking,
1. check, and double-check the battery. Check the gravity, voltage reduction while under operation etc.
The electronics on the truck is very sensitive, when teh battery is weak.
2. Check if there's no short circuit from "+" to earth, specially on the thick cables running to the power modules.
3. Double check the red, hot "Oh God!" button. Very often it looks fine, but the contacts are rusted or covered with some sh...t and not conducting properly.
Anyway, I hope, it's one of these lesser issues, because the modules are extremely expensive.
Good luck
what is the series of the truck
