® is an online automotive complaint resource that uses graphs to show automotive defect patterns, based on complaint data submitted by visitors to the site. Refer to Electronic Throttle Actuator Control Module Replacement. An inspection of the fuses may lead you to the circuit that is shorted to the TAC module ground circuit. Inspect the fuses for the circuits that are in the TAC module harness-i.e.
Clear any DTCs from the memory that may have been set by Reprogramming. If the PCM detects a communication error, DTC U0107 sets. Important: Reprogramming the PCM may cause a communication error between the PCM and the TAC. If the PCM detects a loss of data or invalid data, this DTC sets.
This diagnostic test monitors the accuracy of the serial data transmitted between the TAC module and the PCM. Accurate transmitting and receiving of serial data requires not only good circuit integrity, but also adequate system voltage. This serial data circuit is separate from any other serial data circuit on the vehicle. The throttle actuator control (TAC) module and the powertrain control module (PCM) communicate via a dedicated serial data circuit. Lost Communications With Throttle Actuator Control (TAC) Module ĭo yourself a favor an take it to a qualified repair shop.ĭo you even know what DTC U0107 involves ? I have seen bad power steering control modules short out the data bus (network). Battery positive voltage will then flow through the switch side of the starter relay to the S terminal of the starter solenoid, cranking the engine.Īlso with power steering warning on ,DTC'S are stored in the control module for the electric power steering an or the BCM - body control module. If the ECM has determined that the transmission is in Park or Neutral and theft is not active, it will ground the control circuit of the starter relay. Placing the ignition in the START position sends a message to the engine control module ECM requesting engine start.
With the PNP switch in either the Park or Neutral position, battery positive voltage will flow to the starter relay coil supply voltage input terminal of the engine control module (ECM) and the coil side of the starter relay. With the Run/Crank relay switch closed, battery positive voltage flows through it and on to the park/neutral position (PNP) switch. Once the ignition is placed in the Run/Crank position, the control circuit of the Run/Crank relay is grounded by the body control module (BCM). You have no idea what happens when you turn the key to start your vehicle.įor ignition switch power modes refer to Body Control System Description and Operation. One bad module on the GMLAN serial data network is all it takes for a no start.
Having a qualified professional with proper diagnostic tools checking computer system's is. Disconnecting battery cables an touching them is not the answer. You have no idea of the complexity of the electronic's on your vehicle. What do I try next? You take your vehicle to a qualified repair shop.
