Re: 2009 service ECM / Traction control
I have the same problem as described by Reallove. Engine begins to stutter, Reduced Engine Power flashes on the DIC, and the Traction Loss icon also lights up.
The fault code has always been P1682.
To get the stuttering to stop, I would disconnect the battery for about 10 mins, (sometimes 20 mins), and reconnect and start the engine. EVERYTIME this has happened, and I have had to disconnect the battery, I have noticed that the tEmperature of the ECM has been extremely high (burning hot). And the battery too.
I was compelled to change Ignition coils, but he problem still persists.
Unfortunately for me, I have no GM or Chevy dealer here in Ghana to advise.
A friend who is certified to fix Ranfer Rover, BMW, Porsche and Mercedes and has a GM diagnostic equipment diagnosed the fault codes to be P1682 as earlier indicated.
I am losing interest in this car, an 09 Chevy Malibu LT with 77984 miles on the engine.
Your help will be appreciated.
