CAN C Bus Indirect Input Signals

A 2.5-volt bias (operating voltage) is present on the CAN C 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 C bus is used for module data exchange only. The indirect inputs used on the NAG1 electronic control system are:

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