Finally, I have nearly finished the process of clearing out a 1/2 dozen codes on my LS400. However, I seem to have one that is giving me fits. Its a code 47. Also the CEL stays on, as well as the trac lite. Any suggestions would be helpful. Tips I got earlier were very helpful in clearing out the code 13 ( a broken hid wire to sensor.) After I cleared as many of the codes that I could, I used the clear codes procedure by taking the neg wire off the battery for a few seconds. I'm hoping its not the main ECU.

Google it...it comes right up

code 47 can be caused by 3 or 4 different things:

● TRAC TPS sensor
● ECU
● TRAC ECU (some models have a separate TRAC ECU)
● open or short in wiring between these components mentioned above

please follow the troubleshooting steps in the factory repair manual

PS - I would disconnect the negative battery cable overnight, not just for a few seconds

Code 15 has been added to code 41. ( Both of these codes come up on the air bag light using the suggested procedure for removing the air bag light. ) I have tried another 50 times to remove the bag light, using the posted procedure- to no avail.. There is nothing wrong with my air bag- I had no trouble with this light until I forgot to remove the neg cable from the battery before removing the instrument panel from the dash. I do not see what code 15 has to do with the bag light.. Any suggestions as to what to try next would be appreciated.
