Diagnostics

The engine management warning light indicates either a fault with the emissions or a mechanical failure of the engine components.
We can read fault codes, program the engine ECU, program new injectors and diesel pumps, reflash the engine ECU to the latest calibration files, and carry out basic settings on other components including EGRs, throttle bodies, and many more.
Often an engine warning light will come on if a vehicle has not been regularly serviced.
MAP will always present you with a detailed copy of any diagnostic information that we pull from the vehicle, as well as our recommendations on how to address any issues that we may find.

The Anti-lock Brake System (ABS) has a sensor that measures the wheel speed on each road wheel. When the engine is started, the ABS system carries out a self-test and if no faults are registered, the warning lamp will extinguish.
We are able to diagnose faults and program the ABS pump.

Working in conjunction with the ABS system, the traction control system is responsible for applying the brakes to any wheel that it determines to be turning faster than the calculated speed of the other wheels (with exception to the front wheels) when turning.
In order for this calculation to be carried out correctly on the front wheels, the steering angle sensor, which measures the rate of turn, is required. This steering angle sensor needs to be calibrated to a zero-point with both front wheels in the straight-ahead position. This calibration is necessary when the steering column, the steering rack, or other suspension components have been removed or replaced.
In some vehicles, this warning lamp will illuminate if there is a failure of the brake pressure sensor which is integral to the ABS pump.
We can diagnose faults, and program and calibrate the ABS, TCS, and steering angle systems.
Here at Mobile Auto Pros, we always recommend that a front end alignment is completed before attempting to calibrate the steering angle sensor.
