engine management light/electrical problem?
#1
hi got problem again with my 02 1.9d 600
From some time had air bag light on constantly so did ask m8 to have a look with his scanner where is the problem- found driver side seat belt pre- tensioner so I did check brown connection and orange to tensioner -all ok but now- m8 said I can clear that code with my scanner and he did but second after engine management light show up-so he have scanned for that too but there was no error code showing up!!! van works fine, no problems with anything but both lights still on- will sort out that tensioner got one on order-how to sort out that engine light? Did notice that when I will close driver door and open something is going on with all dials- speedo, fuel, all of them they jump up and go down???? do think its some electrical problem as if I disconnect battery with positive and connect again on first start engine light goes off but after some drive-switch off and on again light shows up ????? :brickwall: thanks for looking guys Pav

If the eml is on, there must be a code for it.

Not all cheap scanners will read every code, so the scanner used may not be capable of reading it.

You need to establish what the fault code is otherwise it's pure guess work.

Hi, did you do a proper shut down / start up procedure after playing around with the electrics, if not try it first.
Try unplugging / plugging the connector for the pre tensioner as these are well known for giving false airbag faults. Make sure you disconnect battery first!Confusedillyme:

Don't worry about the remote key bit, leave that bit out.
Give it a try, wot have you got to loose.
Air bag warning will come on with both seat pretensioners, steering wheel air bag and any others you may have, if you have a passenger air bag and you disable it via the switch, if an air bag has discharged the a/bag ecu will need resetting. Also if you have bad comms to the a/bag ecu it will illuminate.
The best way of finding this fault would be to find someone with Lexia diagnostics. There is a few people on this site that have it but if you browse the peugeot forums there is a list somewhere with people offering this service.

hi thx for input,
story goes on had lexia connected to ecu- 3 codes-drivers seatbelt pretensioner -fail, something with air bag ecu - not known and passenger air bag - not know! that last one is strange as in that model there was no passenger air bag- all codes are permanent ,so I done cheks on all connectors, all cables and all is ok we cheked pre tensioners both ok. Notice one thing: when wiggle some cables in main connector to airbag ecu and switch on ignition - air bag light shoes up then goes off and after 2 sec goes back permanently.Read that it is some pre check but not sure.Can you reset air bag ecu? how often it fails? Thanks for looking guys all feedback welcome cheers Pav:brickwall:

The air bag ecu is underneath the center console. Check the earth points around this.
Do a shut down procedure and disconnect the battery then try unplugging / plugging the orange connector to it as there are bridging pins in this to disable functions that you don't have eg. passenger air bag.
Lexia can reset your ecu but be warned, messing about with air bags or pretensioners with power on could in the worst case fire them off.

Was the ecu fault something like "Data Van A (or B)"?
Really we need to know what lexia read exactly to help you.
