Mazda Trouble Codes and Retrieval OBD1
Start Engine Step 2 - Next, install a jumper wire from the TEN terminal to the GND terminal, located either under the dash or hood depending on model.
Turn Ignition Key "ON" Step 4 - The check engine light will start to blink, count the number, this will be the first number of the two digit trouble code. For example, if the light blinks two times and then pauses, the first number of the code is 2. After the check engine light pauses, the start of the second digit generation has begun. For example, if the second set of blinks equals eight, the trouble code digit will be 8, together with the first digit the code will be 28.
