Showing items 1 - 11 of 11 results.
Does anyone have a sequence of operation list for the drive operation of this unit? My main contactor kicks on and what I believe to be the steer motor is kicking on. The seat switch only shows.7v going to it but I can tell if this traces back to the controller in the dash or not.
The accel pedal gets a 10v feed but when checking resistance, the reading goes from 4.07 to open. Nothing in between.

** I believe my issue is the module in the dash but I need a wiring diagram showing the path of the seat switch feed.

Hopefully y'all can help me out.
I work for an old TCM dealer but we do not have this manual.

First confirm that it has control panel on front left side made by Hyundai. Contactor panel is mounted under the foot rest plate. It has Force ventilated drive motor. Drive motor fan is operated by Inverter mounted on Front Right of steering, can be reached by lifting the top plate of front panel.

If yes then check if drive contactors are energising or not, can you hear the contactor sound when you select the drive?
Did you check the small voltage regulator mounted with the main control card, output should be around 13 volts.
Check the accelerator pedal, Setting should be from 0 to 9 volt output.

Confirm above and skype me @ adnan.khalid143
