Can Bus Indirect Input Signals

A 2.5-volt bias (operating voltage) is present on the CAN bus any time the ignition switch is in the RUN position. Both the TCM and the ABS apply this bias. On this vehicle, the CAN bus is used for module data exchange only. The indirect inputs used on the NAG1 electronic control system are:

  1. Wheel Speed Sensors.
  2. Transfer Case Switch Status.
  3. Brake Switch.
  4. Engine RPM.
  5. Engine Temperature.
  6. Cruise Control Status.
  7. Gear Limit Request.
  8. Throttle Position - 0% at idle, 100% at WOT. If open, TCM assumes idle (0% throttle opening).
  9. Odometer Mileage
  10. Maximum Effective Torque.
  11. Engine in Limp-In Mode/Mileage Where DTC Was Set.
