About Diagnostic Computers for Trucks & Cars

Automobile diagnostic tools help mechanics pinpoint problems.

Diagnostic computers are invaluable tools in troubleshooting problems with vehicles. Used by mechanics and consumers, the computers come in a variety of sizes and price ranges and enable users to locate problems with a vehicle's electrical or brake system.

The Facts

Truck and car diagnostic computers save time and labor, according to JC Whitney, an automobile parts and accessory retailer established in 1915. The company explains that diagnostic computers prevent expensive repairs to the vehicle by identifying the location of the problem quickly.

Computer Code Reader

A computer code reader identifies engine problems in the vehicle. The reader obtains engine error codes when plugged into the diagnostic link connector, under the dashboard. Another type of code reader is a brake scanner, which identifies problems with the pump motor, wheel speed sensors, brake control module, solenoids and the brake switch.

Multimeters

Multimeters locate wiring problems within the vehicle. The meter measures volts, amps and ohms in the electrical wiring and ignition system in the vehicle.
