I'm running through electronics right now, just making sure everything in that dept is OK.
I was running down the IACV tests and it passed so I continued on to the "Idle Speed Stabilization Test"
I was unable to pass the "Input signal to idle speed control unit" test...
"Battery voltage in position P or N....when in D voltage drops."
I placed the + probe to in 12 and - to battery ground, and no voltage was present in either case of P/N/D
Then I placed the + probe to pin 12 and - to battery voltage and in P/N I got batter voltage..and in D I got battery voltage...no drops.
According to the guide, I should repair the open circuit according to the wiring diagram...
What I dont seem to understand is, based on the wiring diagrams from the ETM, That pin 12, should only be given voltage when the key hits the start position...
Any thoughts on this?
