Theory Of Operation
The fuel level signal is a direct input to the Cluster. The fuel level signal is sent to the TIPM over the CAN B bus circuit. The PCM receives the fuel level signal from the TIPM over the CAN C bus circuit.
The ambient temperature sensor signal is a direct input to the TIPM. The TIPM sends the PCM the ambient temperature signal over the CAN C bus.
The PCM receives the vehicle speed signal over the CAN C bus from the Anti-lock Brake Module.
The A/C Pressure Transducer signal is a direct input to the TIPM. The TIPM sends the PCM the A/C pressure signal over the CAN C bus.
The PCM receives
Wheel speed and wheel distance CAN bus messages from the Anti-lock Brake module.
A/C Pressure, Ambient Air Temperature and Fuel Level CAN bus messages from the Totally Integrated Power Module.
The ABS Module sends vehicle speed information over the CAN C Bus circuit to the PCM.
The ABS Module sends an implausible distance signal over the CAN C Bus circuit to the PCM.
The ABS Module sends an implausible distance signal over the CAN C Bus circuit to the PCM.
