Car Forum / Dodge / Dodge Trucks / October 2005clear trouble code
Does anyone know if the trouble codes detected and stored in the PCM can only be cleared by using the OBD-II scan tool, or we can do it by simply disconnecting the system from the battery? Thanks. - P > Does anyone know if the trouble codes detected and stored in > the PCM can only be cleared by using the OBD-II scan tool, > or we can do it by simply disconnecting the system from the battery? > Thanks. > > - P (holds envelope to forehead to divine information as to year and vehicle) Sorry my pshycic powers are non functional today.

I thought the ODB-II codes and the related processes are quite standardized. > > > Does anyone know if the trouble codes detected and stored in > > > the PCM can only be cleared by using the OBD-II scan tool, [quoted text clipped - 11 lines] > I thought the ODB-II codes and the related processes are quite > standardized. Pulling the battery will shut off the light. BUT unless you have repaired the problem that set the code it will come back anyway. If your getting the vehicle inspected soon in an area that checks for codes tell them you had the battery out. >> > > Does anyone know if the trouble codes detected and stored in >> > > the PCM can only be cleared by using the OBD-II scan tool, [quoted text clipped - 26 lines] > ----= East and West-Coast Server Farms - Total Privacy via Encryption > =---- This won't work for NYS inspection. Some codes are set after certain tests are run. These tests run during certain driving cycles. Disconnecting the battery makes these tests start over again. If you go in for inspection, right after battery disconnect, any test that hasn't had the required amount of drive cycles will show up as incomplete. You are only allowed 2 (3? not sure of the number) incomplete tests before your inspection fails. > >> > > Does anyone know if the trouble codes detected and stored in > >> > > the PCM can only be cleared by using the OBD-II scan tool, [quoted text clipped - 33 lines] > of drive cycles will show up as incomplete.

If you inform them before they hook up they will usually scan for the drive cycles and either tell you to leave or if your OK they will run the test.

Yes, that will clear the code, but here in Texas (likely pther areas too) you won't pass the emissions test. Whenever you disconnect the battery or reset your ECU with an OBDII scan tool your ECU will store several "not ready" codes indicating that a recent reset has occurred. It will take typically somewhere between 50~100 miles of driving for these "not ready" codes to clear and change to "ready". The inspection station should explain this to you and tell you to come back in 48 hours and put at least 50~100 miles on the vehicle between now and then. They will also usually give you a retest for free. This should also be explained on a large placard on the wall of the inspection station. The OBDII emissions test can also determine if your "check engine" light is defective (i.e., bulb removed). It does this by telling the inspector whether or not the MIL lamp is on. If their test says it should be on but it isn't on, they will make you get it fixed before they will pass you. >> Pulling the battery will shut off the light.

He had sold the truck with the agreement that the stock sound system would be put back in.. disconnected the battery to change sound systems and held up the sale of the truck for 3 days until he could pass smog.. lol >Common Urban Legend (and false) is that if your vehicle has a "check >engine" code stored you can clear it by disconnecting the battery for 30 [quoted text clipped - 28 lines] >>and watch them roll on the floor laughing and then they tell you to drive it >>for a couple hundred miles before youo try to get it inspected again mac Please remove splinters before emailing |
