Hi,
Background:
- Bought a Fiat Qubo with a handicap passenger seat installed. (Airbag, seatbelt wires etc. were not used, just laying under the seat)
- Replaced the seat with an original from a another Qubo (plugged in airbag, seatbelt wires etc.)
- Now I have an error light on the passenger airbag
Solutions i have tried:
- Went to a garage who had a tester/reader
- They were not able to turn off the airbag light
- If we unplugged the airbag cable from the seat, the warning light goes off.
- With the tester he could read the ohm resistance on the airbag unit. As soon as the wires were plugged in, it read to low resistance, and gave the error.
- Unplugging the wires, and the tester read normal resistance, and no error
Thoughts from the mechanic:
- He thinks the company who installed the handicap seat, has done modifications to the airbag ecu, so it thinks something is plugged in, even if its not
- Or there could be soldered in a resistance somewhere on the harness to the airbag/seat
The mechanic was not able to do changes to the ECU with his tester.
Do anyone have any suggestions/experience how to look even further into this? And how one could modify the airbag controller/ECU again, so it sees the airbag resistance correct.
All ideas are welcome, would love to have the airbag plugged in, with no errors! I will try and look through the harness, but i need to disassemble a bit...
Hope someone can help me further
