This adapter cable connects the 17-pin diagnostic connector of older Mazda passenger cars to a scan tool with a 16-pin OBD2 plug. The connector is located under the bonnet, usually near the left wheel arch or strut tower, in a box marked DIAGNOSIS.

Via this connector you read out the engine management system. Depending on the model, the vehicle communicates via the K-line or via J1850 PWM. The cable physically converts the connector; the scan tool itself must support the Mazda protocols of this generation.

BENEFITS

✔Makes the 17-pin connector under the bonnet usable for a scan tool with an OBD2 plug.
✔You use your existing scan tool with a 16-pin OBD2 plug; a separate Mazda tester is not required.
✔One cable for several model ranges, from the 323 and 626 to the MX-5 NA and NB.
✔The cable works passively: no software or settings are required.

POINTS TO NOTE

✕Your scan tool must support Mazda diagnostics via the 17-pin connector; the cable does not convert protocols.
✕A simple EOBD code reader does not work with this cable; it only reads emissions-related OBD2 data.
✕On the 626 (GF) prior to the facelift, communication runs via J1850 PWM; your scan tool must support that protocol.
✕Not required for later Mazda models with a 16-pin connector in the interior.

Applications and functions

This cable is intended for garages and mechanics who read out older Mazda models with the 17-pin connector.

Control units you can access

  • Engine control: Injection and engine management.
  • Communication: K-line or J1850 PWM.
  • Other systems: Varies by model and specification.

What you can do

  • Fault codes: Read and clear.
  • Live data: Where the scan tool offers it.
  • Fault finding: Check sensors and signals.

How to use it

  1. Locating the connector: Open the bonnet and find the DIAGNOSIS box.
  2. Connecting: Insert the 17-pin plug straight into the connector.
  3. Connect the diagnostic tool: Connect the 16-pin plug to the cable.
  4. Ignition on: Switch the ignition on without starting the engine.
