Technical airbag/child seat light & others

[stephen2682]

hi, newbie here to the forum, in desperate help in regards to my 2.2 jtd ulysse.

the airbag light and child seat light are on, the switch on passenger side is on, but what is the fault? is it a common thing with these cars?

also i have p0020 p0021 p0023 p0025, which are camshaft actuator sensor and timing advanced and retarded on bank A and B, what is the cause, anyone how please?


regards

Airbag warning could be several things, wiring, airbag, connector but is commonly down to a faulty comm2000 unit.

What about the codes? Camshaft actuator solenoid on bank a & b, and timing advanced and retarded!?

 

[FRANTIC FRAN]

I would suggest a camshaft timing sensor

is the comm2000 the airbag ecu?

 

[FRANTIC FRAN]

No the airbag ecu is under the carpet between the 2 front seats. It can be faulty due to water ingress ( heater matrix leaking into the well etc) but it is neatly always down to the com2000 unit on the steering wheel.

Where is the cam sensor? The engine looks crammed in, no space to even look, is there one or two?

I noticed the washer jet switch as been wired to a seperate switch on my Ulysse dye to the stalk not working, are these linked?

I would defo get a replacement com2000 unit. See Fran he may have one.

Already tried 2 from Fran, still the same

did the com2000 resolve the horn/washer side of life?

 

[stephen2682]

No it didn't

Actually the washers are connected to a different switch by previous owner! So only the horn doesn't work
