Tech Tip: Steering Position and Yaw
The Electronic Stability Control (ESC) program uses the Anti-Lock Brake System (ABS) and Electronic Throttle Control (ETC) to maintain vehicle stability in a cornering maneuver. The ESC program requires the communication between the Engine Control Module (ECM) and ABS controller. This communication takes place on the Controlled Area Network (CAN) buss of the vehicle. The program uses input from the following sensors: steering wheel position, throttle pedal position, throttle position, engine speed, brake switch, wheel speed, yaw and ….

Tech Tip: Diagnosing and Servicing 4WD Bearings
4WD operation can be hard on wheel bearings and seals. The most common complaint you’ll encounter is no 4WD operation, which can usually be traced to problems with the vacuum-actuated front hubs. Some manufacturers require that the driver shift the transfer case into four-wheel-drive, choosing either high- or low-range gearing. The driver must then flip a switch that opens a vacuum-control valve, sending vacuum to the locking front hubs and engaging them to ….
Tech Tip: Proper Tools Essential for Handling TPMS Issues
