PSCM - U030000 Volvo XC60 D3 2012

[larop241]

Hello everyone

Currently Im in battle with one of my projects.
Volvo arrived with unknown issue. After diagnostic and checking I did notice pump was changed for other one but unfortunately they didn't backup. Issue is how to program it or what to do ? I do have option for data flash in VDash but this is only experimental option.

Experimental give us error Negative 31 ROOR
IMMO Failed 0x07

Could anyone give me some ideas it will be helpfull.

Thanks

@larop241 in which colour is the PSCM shown in Vdash/VIDA? Red, yellow, gray? Are there any other DTCs in the car, or just PSCM-U30000? That code means no communication with the module or incorrect CEM configuration. Was just the pump replaced or the whole steering rack? Is some information like hardware/software numbers shown in Vdash when you click on the PSCM?

Hello

Module is yellow, showing all ecu numbers etc. Looks like pump was replaced for other one but they didn't program it.

Codes:
CEM U013100 - Lost com with PS
PSCM U030000 Software
PSCM U012600
PSCM U012900
PSCM U014000

Thanks

@larop241 It really seems like your steering pump was replaced with a used part from another car that had a different type of steering installed.
Try if you can read the configuration from the PSCM to compare it to your CEM config. Open ECU diagnostics in Vdash, select PSCM/Others/PSCM Vehicle Configuration Parameters and if you get parameters, compare the values to the CEM configuration shown in the car configuration menu of Vdash.
If the parameters are off, you have two options now.

1. Find someone with an official VIDA subscription and get a software reload for the PSCM. This is not possible with Vdash.
2. Adjust the steering type and gear settings in the CEM to the ones of the PSCM with Vdash and see if the errors disapear, but you might have to swap in a matching steering gear for that configuration afterwards. CEM pin is required for this.
   But first you should try to contact the former owner of the car and ask why the pump was replaced in the first place.
