How to Check Codes on a 95 Protege

Mazda Proteges built in late 1995 and after came equipped with automotive diagnostic systems. When a warning light illuminates on the dash of the Protege it means a malfunction has been detected and a problem code has been stored inside the computer. Generally the malfunction must be repaired and the code cleared before the warning light will go off. Each malfunction code has a designated number that allows the driver to know which component is in need of repair.

Instructions

1

Ensure that the ignition is off. Hook the automotive scanner to the diagnostic connection plug below the steering wheel.

2

Turn the ignition key to the accessory position. Turn the scanner on and follow the on-screen instructions to locate the code. Once the code is flashing across the scanner screen, write down the code number in a notepad.

3

Turn the ignition key back to the off position and open the vehicle repair manual to the "Engine Codes" section.

4

Compare the code to the designated code number in the vehicle repair manual. The code number in the manual will be assigned to a designated component. This will be the component in need of repair or replacement.
