Peugeot 3008 - 0362 Seatbelt Warning Lamp problem

[mattyb_uk]

Hello. I am having a nightmare with my 2010 3008.

A light has come on the dash and an error code about the Airbag / Seatbelt tensioner. A fault code of 0362 comes up when a snap on device is plugged into it, suggesting that the Airbag Disable Warning light has malfunctioned (not characterised). The seatbelt display above the centre console shows that the passenger airbag is disabled and the seatbelt lights no longer work.

It's presently at a garage and they have tried a replacement BSI, Seatbelt Display and Airbag ECU and it's still displaying the fault. It's also had a replacement battery. Does anyone have any idea of what it could be?

thanks

Change the garage first of all - they should never have even replaced the BSI - almost 100% sure it won't be anything like that.

It's very likely to be a wiring connection between the Airbag ECU and one of the airbag or seatbelt devices. It needs a proper diagnostic with Diagbox to get a proper fault code that will generally begin with a letter and then have 5 to 7 other number / characters. That should provide some further assistance. If you have the proper codes, pop them up with your VIN (automasked when you submit your post).

Also, can you confirm if you've had any other work done recently or wired in any other aftermarket device lately like a dash cam or changed the head unit for example?

Hello!

thanks every so much for the reply. they haven't charged me for anything and have only dropped a donor board in temporarily (but obviously didn't connect it fully to make sure the Odometer wasn't overwritten).

They tried the BSI first as it appears to be responsible for the Signalling to the Seatbelt display above the mirror and if the seatbelt display doesn't receive output for 2 seconds then the warning light comes on the dash, with a generic "Airbag or Seatbelt tensioner" error. The seatbelt display above the mirror is permanently suggesting that the passenger airbag is disabled with a X2 symbol and it no longer detects the seatbelts that are connected.

They plugged in a snap-on tool and it's given the output of "P0362 - passenger Airbag Deactivation Led - not characterised". Is a diagbox a different tool I assume?

It used to pop up the error on the clock display intermittently - ie the beep and error would appear up and disappear and after a while, it just came on all of the time. I thought that was because maybe a wire was loose or something.

I haven't done any work on the dash or or changed the head unit. The only thing that I had to do a long time ago was remove the middle seat buckle as the seatbelt tensioner had locked when I had the seats down and I couldn't release the seatbelt from the buckle. I had to use a ratchet to release the bolt and I think it was glued in. Do you think this could be the source of the issue? Ie is the bolt slightly loose or something? I was wondering whether the issue is related to the seatbelt sensor interfering with the Seatbelt display module rather than the airbag itself.

If I can get them to get a diagbox to generate a code, I will do so asap or speak to them about options. they've been pretty friendly but are stumped.

Hey folks. the code is 7362. I have the car back now. anyone any ideas at all?

has had

BSi checked and temporary donor board tested
Disable bag switch replaced
seatbelt display replaced
airbag ECU replaced
clock replaced

the garage sunk about 20 hours in and can't find a solution.

Hi

This is the descriptor for the 7362 Fault: So it is possible the BSI has not been configured correctly.

Fault Code:	7362
Description of Fault:	Passenger airbag deactivation warning lamp fault : Not characterised. Fault is triggered when ignition is switched on. Display of the air bags and pre-tensioners fault warning lamp / symbol. Possibility 1: The warning lamp lights permanently and remains lit Possibility 2: The warning lamp is permanently off Possibility 3: The information "warning lamp faulty" is sent by the BSI (BSI) for more than 2 seconds
Conditions for Fault to clear:	The warning lamp information is coherent for more than 2 seconds.
Downgrade Modes whilst Fault is active:	Recording of the fault in the built-in systems interface (BSI) faults log (JDD) Inhibiting of one or more ignition modules (In the case of the failure of a component of the disarming system or passenger air bag, forced inhibiting of the passenger air bag, switching on of the passenger air bag disarming warning light)
Symptoms:	Display of the air bags and pre-tensioners fault warning lamp / symbol
Suspect Areas:	Configuration (BSI) Seat belt not fastened warning lamps unit Instrument panel

hey Marc

Thanks. this error started intermittently over the period of a year and then came on permanently. it's had a donor BSI in and the error still appeared. Spoke to another garage who were adamant it's not the BSi. All of the other suspect areas have been ruled out. it's absolutely vexing.

[mattyb_uk]

NB the centre console display doesn't show the seatbelt LEDS anymore and that has been replaced too.

[GiveMeABreak]

The system would need looking at for sure as the fault suggests that one or more of the ignition modules may be disarmed causing one or more airbags to not be triggered in an accident and of course an MOT failure if the airbag system is faulty.

The only thing I can suggest Matt is to get it checked with Peugeot, as this is an unspecified fault code. You may have a faulty connection or Airbag ECU. Pop your VIN up and I'll see if there are any technical issues reported.

[mattyb_uk]

thanks fella. here's the VIN
VF3**************[VIN obfuscated, can be read by forum staff]

[mattyb_uk]

btw the Airbag ECU was replaced too.

[GiveMeABreak]

Then I'm at a loss. If it was a wiring issue, I would expect to be getting a specific fault code for that.

As far as the technical bulletins go there are a few under the airbags. I can't tell you what they are as these are chargeable, but these are what they list:

• Displaying of the air bags and pretensioners fault warning light/symbol without any fault code in the air bags and pretensioners unit.
• Intermittent display of the airbags and pretensioners fault warning lamp/icon.
• The air bags and pretensioners fault warning lamp/symbol does not come on when the ignition is switched on (ignition in the ignition positive position).
• The passenger air bag disarming warning light does not come on when the ignition positive is switched on.
• The position of the passenger´s air bag disarming switch is not coherent with the lighting of the warning light.

Sounds like 4 and 5 might yield something! I'll have a think mate. thanks for this. sounds like a return to Peugeot or onto eBay for someone else to have a crack.

[mattyb_uk]

the only thing I can think of is that a while ago, the middle seatbelt got stuck after having the seats down so I had to undo the bolt which held the centre Belt buckle in place. that's not connected to anything is it?

[GiveMeABreak]

The rear seats belt buckles have sensors in Matt, so with this new info, it is possible that the wiring to the buckle has been snagged or damaged.

Hey fella -- I've put the car on ebay and a guy has reached out to me and said that he has seen this problem on several Peugeots - he's from a business called Autosparx. A nice dude named Geoff.

he said that there appears to be an issue with the additive pump underneath the rear passenger wheel - (I assume with the control board) and that problems with it can presumably causes issues with the very sensitive airbag system in the car and he had remedied this by replacing the additive pump or mapping it out completely.

he suggested to unplug it and try to clear the fault code. I'm not holding out any hope. I unplugged it yesterday and the airbag fault was still there (I don't have an OBD adaptor to clear it properly) but strangely the car did not complain on the dash about the anti-pollution system or about losing any connectivity with the additive pump? Not sure if there is something going on here and perhaps whomever I bought the car from has been messing with the anti-pollution system and/or ECU?

I've ordered an ODB with extensions so I can see what codes are being logged.
