I did the key dance and recieved a P 1388 code which is variable cam timing over retarded (Bank #2). Does anyone know the fix for this? Please tell me that I don't have to take it to the stealership.

Mil Gracias,

 

a P1388 is an open or short detected in the ASD (automatic shutdown) relay control curcuit.

SYMPTOM

WHEN MONITORED

SET CONDITION
An open or shorted condition is detected in the ASD Relay control circuit.

POSSIBLE CAUSES


Intermittent condition

Thanks for the reply. I don't have a DRBIII. I use to work in the Jeep Assembly plan in Toledo so I do know what that is but wouldn't know what to do with it if it hit me in the head.

I was working on my heated mirror issue and was unplugging some of the electrical switches in the doors. Would something like that set it off? Could I do the old unplug the battery trick to reset it?

 

you only need the scanner to make sure that the code you are diagnosing is still present, the rest can be done with an multimeter.

 

Helms! Where did you find that? It looks sort of like the site I couldn't find a while back with that other issue, LOL And don't tell me you can't find it now! LOL

 

I think Helms has AllData.

 

The info I found with that other issue was probably/maybe info someone posted from Alldata, but I don't think so. Oh well.

 

ya, all this comes from alldata

 

Whoa...What's that?...lol
