PMU Wiper control

PMU
1

Hi,

so I’m looking for a solution to run my Honda wiper from the PMU. I have seen that the PMU has a specific Wiper slow speed output, but these are +12V switched. The Honda wiper motor has constant 12V and the low or high speed windings are switched to ground to be run (so the opposite as the PMU does).
There seem to be 2 solutions for this problem:

  1. run a 5 pin relay which will be switched by a second output on the PMU, but that makes things more complicated, and is not the way I want to go.
  2. Run the high speed winding with PWM with 0% duty cycle, 50% duty cycle for slow speed and 100% duty cycle for high speed.

Do you think option 2 is do-able with the PMU16/24?

Best regards

normally 12v permanent is for parking and 12v for fast and slow separately… what Honda is that wiper motor from?
