Service AWD strikes again

Recommended Posts

Have own my 2013 DJ for years and always get the service AWD like every winter. I've come to accept that dealership always has an excuse why nothing is wrong. Matter fact it even did it on the drive home when i bought it.

 

Now today it is sunny and dry and warm weather outside. On my way home from work the service AWD light came on. Thought it odd since i was not driving aggressive. Further on my way home the engine light came on. Made no noises or drove any different then normal. 

 

Drove further home and the info screen on gauges went completely black. On a whim turned on headlights and it light back up. Stoped and turned off vehicle and restarted my DJ and AWD light and engine light came back on.

 

Anyone ever had this happen especially in dry warm weather?

It sounds like it might be an electrical issue. I would start by disconnecting the battery for at least 30 minutes to reset everything. If that doesn't work you may want to check for shorts in the wiring (if you feel comfortable), or take it to the dealer. I know the AWD system uses a multitude of sensors, and one may be going out. I'd do the reset, check fuses, and if you don't find anything obvious take it in.

was able to connect my OBD2 reader this morning, son had Subaru it was in last night, and gave me codes for ECU for SRS and fuel gauge. But not for the service AWD. Drove it a bit this morning and check engine light came on right away and the traction control light stays lite, forgot to mention that one before, but no codes for it.

 

tried to clear them in tje event it was an isolated issue or just car being weird.

 

they instantly cane back on. 

 

here is a screenshot of codes

According to what it says they are either for no communication from ECU to SRS or fuel level

I know this an old post but found my alarm was the issue. It interfaces with canbus at obd2 port. Went crazy one night on me. When i went to start it it said push in clutch. That one had me scratching my head for a second. But disconnected alarm and all my gremlins went away.

That's cool! I don't have to worry about my wife borrowing my DJ. She can't drive a clutch! :bliss:

 

It might be fun watching her try to find it though. :headspin:

How did you disconnect or reset the alarm? Mine won't start since I think it went  into ignition disable mode.... but it set off everything from park assist, battery, not in park, check engine light to service awd. Service awd doesn't have anything in message centre to say why nor does it turn over in run.  I tried putting actually key in for door to possibly let it disable, to pushing the push start with the fob....I am literally stuck....

I have an aftermarket alarm. The bypass module for ignition taps into canbus at the obd2. I just disconnected the power to thr bypass. Alarm itself still works if someone broke in but the keyless entry and remote start is not since the bypass module is not powered.

 

If you have a aftermarket alarm i would try disconnecting power to the alarm. If you are referring to factory alarm only thing i could think of is to disconnect battery for 10 minutes and reconnect.
