Do you even know what DTC U0107 involves ?
DTC U0107
Lost Communications With Throttle Actuator Control (TAC) Module

The throttle actuator control (TAC) module and the powertrain control module (PCM) communicate via a dedicated serial data circuit. This serial data circuit is separate from any other serial data circuit on the vehicle. Accurate transmitting and receiving of serial data requires not only good circuit integrity, but also adequate system voltage. This diagnostic test monitors the accuracy of the serial data transmitted between the TAC module and the PCM. If the PCM detects a loss of data or invalid data, this DTC sets.

Diagnostic Aids
Important: Reprogramming the PCM may cause a communication error between the PCM and the TAC. If the PCM detects a communication error, DTC U0107 sets. Clear any DTCs from the memory that may have been set by Reprogramming.
• DTC U0107 sets if the battery voltage is low. If the customer's concern is slow cranking or no crank because battery voltage is low, ignore DTC U0107. Clear any DTCs from memory that may have set from the low battery voltage condition.
• DTC U0107 sets when there is a short to B+ on the TAC module ground circuit. Inspect the fuses for the circuits that are in the TAC module harness--i.e. cruise, brake. An inspection of the fuses may lead you to the circuit that is shorted to the TAC module ground circuit.
Replace the TAC module. Refer to Electronic Throttle Actuator Control Module Replacement .
Did you complete the replacement?

Where is the pcm located on my vehicle


It should be right on top of the battery on the drivers side of the engine compartment. They may be a plastic cover over it.

PCM's are the last thing I consider when diagnosing a vehicle. In the last 20 years I have replaced less than 10 PCMs or "computers" that have failed to operate as intended.

PCM replacement on your vehicle is expensive and it will need to be reprogrammed with special equipment once it is installed. Making sure this component is the true source of your problem will not only save you money but also headaches in the long run.

  • 2001-2005 ESCAPE 3.0L UNSTABLE IDLE - 2001-2003 ESCAPE 3.0L AUTOMATIC TRANSAXLE SHUDDER - MEXICO ONLY
Publication Date: May 25, 2006
FORD: 2001-2005 Escape
ISSUE: Some 2001-2005 Escape vehicles equipped with a 3.0L engine may exhibit idle speeds outside the specified range. Some 2001-2003 Escape vehicles equipped with a 3.0L engine and CD4E automatic transaxle may exhibit a transmission shudder.
ACTION: Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
  1. If the concern is a 2001-2005 Escape with idle speeds outside the specified range:
    1. Install a new idle air control (IAC) valve with jumper harness included in the kit. The new Denso brand IAC will be installed with the electrical connector facing the opposite direction of the original (Hitachi) valve which is why the jumper harness is required. The original (Hitachi) IAC connector faces the front of the vehicle while the new Denso IAC connector faces toward the rear of the vehicle.
    2. Referring to the calibration charts (Figures 1 and 2), select the applicable file and reprogram the powertrain control module (PCM) using the TSB Service Procedure and WDS/IDS release B40.5 and higher. Calibration files may also be obtained at www.motorcraft.com.
  2. If the concern is a 2001 - 2003 Escape with transaxle shudder, drain, flush and refill the transmission fluid with MERCON® Multi-Purpose Automatic Transmission Fluid. Then, referring to the calibration charts (Figures 1 and 2), select the applicable file and reprogram the PCM using the TSB Service Procedure and WDS/IDS release B40.5 and higher. Calibration files may also be obtained at www.motorcraft.com.
  3. When reprogramming the PCM use blank path programming. Select the proper file from the chart and manually enter the PCM part number or tear tag number to obtain the updated calibration file.
To Perform Blank Path Programming:
  1. Connect WDS/IDS to vehicle.
  2. Select "16 pin", select "All others, except those below", press TICK.
  3. Screen shows installation of cable, press TICK.
  4. Screen shows to turn ignition ON. DO NOT TURN IGNITION ON. Press TICK.
  5. Screen shows progress bar, then screen tells you "No communication can be established with the PCM" and asks you if you want to retry? Select "NO". With the ignition key still OFF, press TICK.
  6. Screen shows to turn ignition ON. Keep ignition in the "OFF" position, press TICK and you will be asked to cycle the key "ON" and "OFF" a few times. Please keep the key position in the "OFF" position through the key cycles.
  7. Screen will show "The diagnostic tester is unable to communicate with this vehicle." You will be prompted to "select a vehicle from the vehicle list", press TICK.
  8. A list of vehicles will be displayed, select ALL OTHERS, and press TICK.
  9. Screen shows "To enable WDS to reprogram the PCM with the correct calibration", enter one of the following: Vehicle Calibration number (7 digits), Tear Tag number (4 digits), or PCM part number, press TICK.
  10. Highlight the box next to the selection chosen, and enter ONLY ONE of the selections listed above. Press TICK.
  11. Follow and answer correctly all remaining screens. Once PCM is reprogrammed communication should be reestablished and PATS system can be reset (if necessary) per Workshop Manual, Section 419-01.

My 2005 chev tahoe cd player won't play cd's and won't eject them. The cd light keeps flashing. I don't think there is on stuck. There wasn't any signs of trouble before this...


I have run into this problem many times on your particular type of radio. I have worked in a gm dealership for years. Sometimes we can reprogram them and they work better, but all will eventually need replaced. The cheaper option is to have an aftermarket radio installed, for the price of a new factory radio, you could have a much nicer aftermarket unit.
