Note: The definition of code U010C can differ depending on the vehicle manufacturer. 7, 6 speed w/ SBDD 3600 clutch, BD Super B Special 64. you use the alignment pin to set the mechanical side of the brake, then via the starscan command 0% position, or home position on the actuator and then mate the two together. Now I can't get the new actuator to do the primary calibration. However, this code can also be triggered if the battery is weak, or the connections are corroded or loose. Visual inspection and diagnostic tools can help identify mechanical issues with the VGT actuator, such as carbon buildup or faulty sensors. Low Pressure Fuel Pressure Signal Out of A variable geometry turbo (VGT) actuator is a device on an engine that communicates with the engine control module (ECM) over a controller area network (CAN). Automotive Test Solution's eSCOPE Elite is used for the diagn Oct 17, 2019 · Lost comm with the turbo is an electronic issue, most likely an issue in the turbo VGT actuator electronics. 10 - Crank Signal Rate of Change Abnormal ECU 000641.
