Intermittent drivetrain malfunction

rick504 · 01-03-2016, 11:14 PM

I keep getting a drivetrain malfunction light. It comes on intermittently. It always goes away when I restart the car. I used the JB4 software to read the codes and it says reduced power module. If I restart the car the code goes away. Some days it does not happen at all and some days it happens right when I start the car. When I restart the car it might not come back on for days. I'm running map 1 and attached a log. Any suggestions. Seems like the car runs perfect until the light comes on.

current mods-
BMS Intake
Wagner Intercooler
Chargepipe
AFE Exhaust
JB4 Software

problem is fixed. got down pipe installed and haven't had the issue anymore. Not sure how this solved it but have been riding for weeks now with no drivetrain malfunction.

Did you look at the cat inside the pipe? Was it deformed and melted?

i got this error on my 15 after initial install turned out maybe a connector was loose cause i removed it from he all weather enclosure and used the normal one:

then last night i popped my hood to show a friend amd the drivetrain error came back but upon restart it went away

im a little afraid to throw the downpipe on and go fbo if this will continue maybe a flash is the answwr
