Before I start dismantling...

STUBIE · 25th March 2019, 21:24

So had my V6 for a couple of months, no air bag light but on a trip I recently played around with the seat settings as I was getting a bit uncomfortable and Airbag light came on.

Ah well I thought must have dislodged something under the seat but after a quick check under drivers seat and a spray with contact cleaner airbag light failed to go out,

On a recent trip to BigRuss I asked if he could identify where the issue was but T4 refused to communicate with the airbag ecu, Russ stated that its usually the ecu that has become corrupt and needs to be changed with the centre console out.. oh great,

So before I go dismantling could it be anything else if I cannot communicate with the ecu, checked the SRS fuse, it was Ok but changed anyway, Also checked the connections under passenger seat.

If this car is equipped with a Temic SRS DCU it will more than likely be toast if it's an Autoliv variant, then power supply issues are more likely.

So does the car have a modular or a hardwired fusebox Stu?

Does the fusebox have mini fuses or standard size?

The earlier modular fusebox has standard size fuses , post 2003 will be hardwired and have mini fuses.

Standard fuses in this car.

In that case, a replacement Temic SRS DCU is needed along with configuring to the car.....something like THIS

When fitting, with battery disconnected, disconnect the multiplug before disconnecting the flying earth lead, and reconnect the earth and bolt down the unit, before plugging in the replacement DCU.

Hope this helps
