P1388 = Auto Shutdown (ASD) relay control circuit open or shorted.
The ASD relay routes battery power to the ignition coils, and is energized by the PCM as long as it receives signals from both the crankshaft and camshaft position sensors. If the engine stops turning (stalls), the PCM deengerizes the ASD relay and shuts down the ignition system. The ASD relay also supplies battery voltage to the fuel injectors, so when it shuts down it cuts off both ignition and fuel. At the same time, the PCM also deenergizes the fuel pump relay to turn off the fuel pump. For "limp in" capability, the Chrysler system can run with input from the crankshaft position sensor only. The ASD and fuel pump relays are both located in the Power Distribution Center.

Mechanics advised that gearbox needs replace after diagnostic Of codes . Dash light still on after codes being read , have had ecu replaced 2yrs ago ? What do you think it could be , thanks phil


didnt specify vehicle --generic answer--until repair is made the vehicle will show engine light and have codes --if gearbox is problem for limp mode /until repairs are made or gearbox replaced you will be in limp mode --and as to sensor find out what one it was --start problem may show back up if sensor was problem --and GET a 3rd opinion you have 2 mechanics with different opinions on your problem and i guess they are reading your trouble codes differently

Amber gearbox light came on in my 2004 S type Jaguar. After shutting engine down and cooling it started with no light on. So, I limped home. The Q: Now that the light is no longer lit can I drive it? Or,...


you need to have the car scanned for freeze frame data code reading to see what happened at the time of the limp mode...Let me say that at times after heavy rain or even if you wet the fire wall near the throttle body, that can also cause the limp mode coupled with brake, dcs,and gear box fault and engine fault lights etc...You can actually do a hard reset yourself by disconnecting the neg battery terminal for 30 min..Let the car run and take it for a drive to make sure the shift points arent jerky.But have the car scanned and let me know what code comes up.

On a jetta 2006 all the lights on the dash are flashing PNDR ( park,drive and reverse lights) what does that mean. Does it mean the km on the car have been rolled back ?


No, this is a warning signal that notifies you that the gearbox is defective, has been put in Limp Mode (an emergency mode designed to keep the gearbox running at all costs as to allow you to reach home) and it will have to be serviced immediately. It will be very expensive.

Mitsubishi gto only third and reverse gearbox removed and reconed


You need to flash the tcm for codes. You can do this with a jumper wire and a volt meter. But you likely have a bad TCM.
