InCarTec 39-PGA-PDC Citroen and Peugeot CAN Steering Control Interface

Steering and PDC Interface

The 39-PGA-PDC is a CAN bus steering wheel control and PDC retention interface designed for use in Citroen and Peugeot cars. It allows for the retention of the original parking distance
control (PDC) system and enables the use of the steering wheel controls with an aftermarket radio. The interface generates various outputs, including CAN ignition and speed pulse, illumination, parking brake, and reverse gear signal outputs.

Patch Lead Setup

The patch lead connector has four pins and is used to connect the interface to an aftermarket radio. The pin configuration varies depending on the brand of the radio:

• Pioneer and Sony: Pin 1 black (base), Pin 2
  red (middle), Pin 3 not connected, Pin 4 white (tip)

• Alpine, Clarion, and JVC: Pin 1 black (base),
  Pin 2 white (tip), Pin 3 not connected, Pin 4 red (middle)

• JVC, Kenwood, and Zenec: Pin 1 not connected,
  Pin 2 blue (single wire), Pin 3 not connected, Pin 4 not connected

• Chinese/Learning: Pin 1 not connected, Pin 2
  blue (single wire), Pin 3 not connected, Pin 4 blue (single wire)

Note that the diagrams above show the connector viewed from the wire entry side.

Switch Setup

The switches on the interface must be set according to the brand of radio and vehicle model. There are five switches in total; switches 1-4 relate to the brand of head unit, and switch 5 relates to the car model. The following table shows the switch settings for each brand:
