My '95 NSX has its TCS light come on within a second or two of starting. The light remains on while driving. Last year the TCS light started coming on occasionally, but usually once I drove the car a bit and turned the ignition off and restarted it, the light would stay out. It gradually worsened, and is now always on.
I decided to pull the TCS code today, and the TCS light blinks once and then stays on (in contrast, my CEL blinks repetitively due to a catalytic inefficiency CEL). I took a video that I can post to demonstrate my TCS light's behavior:tongue:. Looking at my service manual (page 19-86 for '95 MY), this does not appear to be an actual code. The only one-blink code should be followed by two short blinks if I'm properly interpreting the table on 19-86. Anyway, does this mean that I don't have an actual code? Would that mean that I shouild be looking at the row under "System indicated" that says, "TCS indicator light does not go off after engine is started?" This row contains a dash under Diagnostic Trouble Code, rather than a blink count.
I checked all my tires and added air to bring them to within specs (one was at 20 psi). Just for the heck of it, I also pulled the clock fuse to reset codes, but the TCS light still behaves the same way when running the diagnostic check. I'm heading out for a 20 mile drive, but I expect the TCS light to remain on.
Thanks for your help and comments.
