I don't know what 46 is, BUT:Hello all, I have a 95 impala SS (true SS) I am restoring, had replaced steering column with key and matching theft deterrent module car starts runs badly but runs and only codes I get are 46 and to other codes for A/C. I currently don’t have the cluster in to verify the security light is doing or could that be cause of the 46 code? I originally just bought climb from junk yard and car would not start, so o did research and went back to get the theft module, started right then, how do I get this light to go off and yes rest code every possible way no dice.
THanks im advance!
If you do not know what DTC 46 is you should not be so sure about it not being a VATS problem.I don't know what 46 is, BUT:
If the car is running, you do not have a VATS problem.
Dude... What you just said was exactly my point.If you do not know what DTC 46 is you should not be so sure about it not being a VATS problem.
DTC 46 pass-keyII Circuit.
From the FACTORY SERVICE MANUAL:
DTC46 will set and the engine will stall if the proper signal is not being received on the CKT229 pin(A25) by the PCM after 1.7 seconds.
This is a pulse width modulated signal(squarewave) from 40-60 hertz(55hz).
The car is RUNNING, not stalling after 1.7 seconds. At least, that was my interpretation.
I'm just telling him what #46 doesn't mean.
POST#1The absence of a go signal is not a valid no-go signal, and vice versa. If the TDM decides a theft attempt is in progress when the engine is already running, it will not stop the engine, but it will turn on the “Security” light and enter anti-theft mode at the next key cycle.
