Customer Questions & Answers

What are the physical dimensions and weight of the converter? What is included in the box?

The adapter usually measures approximately 30 cm in total length, with high-strength plastic connectors measuring 58 mm x 18 mm (GM-12) and 46 mm x 21 mm (OBDII-16). The weight is around 110 g. The box includes the adapter cable; instructions or additional accessories are usually not included.

Does it require special installation or additional tools to use?

Installation is straightforward: connect the 12-pin GM end to the vehicle port and the 16-pin end to the OBDII scanner. No tools or additional configuration are required. It is recommended to disconnect the battery before handling electrical connectors for added safety.

What is the estimated durability of the adapter and what maintenance recommendations are there?

The converter is made from ABS plastic and copper wire with a PVC sheath, with an estimated service life of more than 2,000 connection cycles. Avoiding excessive twisting and exposure to extreme heat (above 70°C) increases durability. Maintenance consists of cleaning the pins occasionally to prevent poor contact.

What is the GM 12 pin to 16 pin OBDII adapter for?

It is used to connect modern OBDII diagnostic tools to GM vehicles with a 12-pin diagnostic connector, making it easier to read codes and vehicle data.

Is it compatible with all GM cars?

It is compatible with GM vehicles that use the 12-pin diagnostic connector, typically older models before OBDII standardisation.

How do you use this adapter?

It connects between the vehicle's 12-pin diagnostic port and the 16-pin OBDII cable or scanner to allow communication between both.

Do I need any additional tools to use it?

No, you only need the adapter together with an OBDII scanner or diagnostic tool to carry out the reading.

What is the difference between OBD1 and OBDII in GM?

OBD1 is the earlier diagnostic system with specific connectors such as the 12-pin one, while OBDII is a more modern and universal standard with 16-pin connectors.
