    01 Caravan air bag light on

    I know, I know.. "Another one with the airbag light on??!! Read the posts on this!!"

    Believe me I looked, but couldn't find the answer.

    '01 Grand Caravan 180,000km(110,000 miles approx.)

    A while ago I was told by the dealership that the clock spring was bad, so yesterday I changed it, along with the broken multi-function switch. Fixed one problem... turnsignals are canceling once again but the airbag light is still on. Only error code returned by the key method is that the battery has been disconnected (P1684). Do I need a code reader to clear the airbag light or do I have another problem in this area?

    Thanks in advance

    You need a DRB tool to read the air bag system codes. The fact that the light is on likely means the system knows where the fault is.

    OK, had a friend check for errors today and he said there were no stored errors. He used an ODB code reader, not a DRB.. is there a difference? In any event, going to have a look at some weak points in the wiring that I was told about. Apparently weak points exist in the harness under the seats, and also in the dash to the right of the radio.

    Will see what we can find.

    A DRB is a complete system scan tool, a very expensive item that normally only dealers, body shops, and high end mechanics have. The OBD only reads engine related codes.

    WoWoW!!! Took a quick look on Fleabay and these things run around $3,000 to start.. Guess it's back to " a friend of a friend " who is the service manager at the stealership.

    Hi Brian,
    I almost have the same problem, instead of new thread, I am going to put details here.

    I have 2001 T&C Limited w/150.000 miles on it.

    Airbag light comes on after 5-10 minutes driving, all the time. when I first start no light. after some time it is on.

    So I took the van to dealer to see. Report was "Airbag Module Loses Connection with Instrument Cluster" this turns the light on and turns off the airbag system.
    They said I need a new cluster, circuit board is fault... $900...etc...

    First; I check the wiring it self between cluster and the AB Module. it is the PCI Bus, White with Violet stripe. connection was OK.

    Second; I installed a new clock spring. AB light still on.

    Third; I got a used Cluster from junkyard and installed. AB light still on.

    Fourth; I removed the cluster, re-solder the socket pin connections. AB light still on.

    Also, for the error codes: check the cluster codes. engine off; press and hold the trip button, until you see lights come on. and follow the odometer. This is cluster self diagnostics. it tells you if you have any error codes with it.

    I had these codes with cluster,
    100.1 ABS Communication Fault
    100.5 ORC Communication Fault
    100.6 SBEC/DEC/MCM Communication Fault
    400.1 Improper power down Detected

    So anybody has any ideas,

    Thanks etek. Did the check today and, fortunately, no errors. That was pretty neat tho, watching all the gauges move up, and then back down, and the various lights come on.
