Thread: Rrs?

  1. #1

    Rrs?

    Does any one know what RRS might be?

    This is on a 99 LS1 PCM.

    BLU connector
    Pin #6 on my PCM is RED and Circuit # RRS1
    Pin #7 on my PCM is GRA and Circuit # RRS2
    Pin #53 on my PCM is BLK and Circuit # RRS3

    Every single pin has a GM circuit #, but these three.

    From what I can figure out
    RRS1 is a Sensor signal circuit
    RRS2 is the Sensor 5V ref
    RRS3 is the Sensor Ground

    I have not found the VTD system on system yet if it has one.

    I have no PCM to load the Program on and check this out. I have to wait until next week.

    according to my docs

    #6 - dunno
    #7 - Oil Pressure Sensor +5v
    #53 - Trans Fluid Temp Sensor GND

    I will just order 3 PCM's today and load them.
    I will send Bill one.

    Rough Road Sensor.
    Current readin with bench program harness is .02 volts.

    now I just have to find a RRS for this.
