What wires connect from the OBD to the EAS ECU

thepipersson · Jan 11, 2014

Hello all,

Just wondering if anybody knows of the top of there head, the connection from the OBD to the EAS ECU is only the white and light green wire and the pink and white wire or is there more I would need to check.
I have continuity all the way for those two, but I'm not a sparky and not sure if I'm reading the diagram right any help would be much appreciated.

Thanks

Pin 1 on OBD is EAS delay relay Grey/Red. Pin 11 EAS ECU White/Light green. Pin 12 EAS ECU White/Pink.

Try this . . .

Pin 1- (Grey & Red) EAS Timer

Pin 4- (Black) Ground

Pin 5- (Black & Purple) Ground

Pin 7- (Pink & Red) BECM (Socket C 255)

Pin 11- (White & Light Green) Airbag ECU

Pin 12- (White & Pink) EAS ECU

Pin 14- (Yellow & Green) Airbag ECU

Pin 15- (Light Green & Red) BECM (Socket C 255)

Pin 16- (Brown) 12V+ Feed via 5A fuse (F 33)

Pin 17 on EAS ecu should be going to pin 12 on the OBD and pin 35 should be going to pin 11, Also make sure you've got a common ground going to your power supply and to the EAS pin 18 and to the pin on the OBD 4 and/or 5.

Good Luck.

That is wrong, 11 is not Airbag ECU. Pins 11 and 12 are EAS ECU. Pin 1 is EAS delay timer. Pins 13 and 14 are Airbag ECU NAS only. Pin 14 Airbag ECU rest of world 13 not used.

Or maybe on the single point sensing SRS on the late models. Can't remember now but when I was sorting my SRS problem I wrote the wire in there for a reason.
