Peugeot 207 1.6 HDi 9HX 2007 - No coms with ECU, car does not crank#

Posted by George Rayner on June 5, 2012, 3:59 pm

Year of Manufacture *: 2007
Engine Size and Code *: 1.6 hdi 9hx
( Optional ) ECU Type: bosch
( Optional ) Scanner Used: kts/dec/snap on

Hi All

I have no coms with engine ecu. Car came in as none start, green flag attended, not sure what they tried, car had a small bump hours before, broken head light at n/s and bumper, no pin data to check for power supply etc, got coms in bsi, abs,steering etc, all reporting fault in engine ecu. Car does not crank but you can see signal in under bonnet fuse box. KTS has a good wiring diagram but does not show power in

Am i missing something here.

Thanks george

Not sure if i've mis-read your post but could it be a simple fuel cut off switch as I have seen this over looked and I have done it my self.

Thats the part of the post I didn't understand, not sure if you meant it run afterwards or not.

Hi,
< Have you checked any data/dtc in airbag system? >
Andy is refering to the fact that the Fuel Cut-Off function is built into the airbag system on these and on many other PSA vehicles.
Hope that helps

The wiring diagram I have shows the ecu powers and grounds as being.

The brown 48 pin connector
Pin E1/ wire 1229
Pin M2/ wire 1203A
Pin M3/ wire 1226
All as powers

The Black 32 pin connector
Pin G4/ wire M132D
Pin H4/ wire M132E
As grounds

As suggested crash data in the airbag ecu may stop the vehicle starting.
