Hi Guys,

Looking for some assistance and advice on a rain light and wiper issue I'm having with a pdm30 that I have fitted to an alfa 75 GTA.
I am using a 15way keypad with very little digital inputs.
The rain light is turned on via a keypad button but I cannot get it to flash. I have followed and looked at various examples and still no luck.

I also cannot get the wipers to park. I am using output 9 as specified.
I believe that this wiper motor is only single speed so I'm unsure if that makes a difference.

I have attached my configuration and am open to suggestions to rectify my issues. I am new to pdm installs so please keep this in mind.

Regards,

Marco

Hi,

I have changed the attached configuration to drive the Rain Light from the Keypad button, through a function, to the output. I have also renamed the channels to reflect which operation they are in the PDM so that it is easy to configure them.

With the Wiper setup, it will not park automatically as you do not have a Park input into the PDM, this is needed to inform the PDM when to turn off the output as the motor is in its parked position.

Hi Stephen,

Thanks for your reply and for sorting out my issue with the rain light.
Can I configure the keypad to park the wiper via CAN?
As this vehicle is a dedicated racecar, there is not combination stalk assembly to provide an input into the PDM.

Also, just wondering if you have any references for the CAN addresses to complete my CAN input channels?

Thanks,

Marco

Hi Marco,

The Park input comes from the wiper motor itself, there should be an output from the wiper motor that provides the park signal, this is wired into one of the PDM input pins and is used in the control strategies. Some examples of these are found in the PDM User Manual that is found in the Help menu of the PDM Manager.

I have attached a base configuration with the standard CAN Messaging out of the M1. This is the link to the M1 to PDM CAN Messaging User Guide.

hey there, i'm not an expert but have you checked if the wiper motor has that park signal output? might be worth double-checking the wiring diagram for your specific model.
