How to Pull Codes for a 1988 Mazda RX7

You can pull the codes from your 88 Mazda RX7 using a small computerized device known as an OBD I code reader. These tools can be purchased at any auto parts store. The Mazda RX7 comes equipped with an On-Board Diagnostics I computer (OBD I), which receives and stores trouble codes sent to it from sensors found throughout the vehicle. When a sensor detects a malfunction and sends a code to the computer, the computer illuminates a warning or service light on the instrument panel.

Instructions

1

Locate the diagnostic port found on the drivers side dash. Plug the code reader into this port.

2

Put the key into the ignition and turn it to the "on" position, but dont start the vehicle. This will turn on most code readers. If not, find the on/off switch on the reader and turn it on.

3

Wait for the code reader to interface with the Mazdas computer. Most readers will retrieve the codes automatically; for some readers you have to select the "Retrieve Codes" command on the face of the reader.

4

Write down the codes the reader displays and look up their meanings in the code readers manual.

5

Unplug the code reader and turn off the vehicle. Have the Mazda serviced or repaired based on the information obtained from the codes.
