Compatibility And Fitment<\/div>\n

Compatibility And Fitment<\/h2>\n

This adapter cable is useful when the vehicle diagnostic socket and the diagnostic tool use different connector formats. Please confirm the vehicle-side port shape and pin layout before purchase.<\/p>\n <\/div>\n

\n
\n

For Matching GM 12-Pin Ports<\/h3>\n

Use this cable only when the vehicle has a compatible GM 12-pin diagnostic interface.<\/p>\n <\/article>\n

\n

16-Pin OBD2 Diagnostic Side<\/h3>\n

The cable helps connect to 16-pin OBD2 diagnostic equipment when the tool and vehicle connector are compatible.<\/p>\n <\/article>\n

\n

Adapter Cable Only<\/h3>\n

This product is a connection adapter cable. It does not add diagnostic functions by itself and does not replace a scan tool.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

\n
\n

How To Use<\/div>\n

How To Use<\/h2>\n

Use the cable only after confirming that the vehicle diagnostic port and diagnostic tool connector match the adapter.<\/p>\n <\/div>\n\n

\n
\n

Check The Vehicle Port<\/h3>\n

Confirm that the vehicle has a compatible GM 12-pin diagnostic interface before connecting the cable.<\/p>\n <\/article>\n

\n

Connect The Adapter<\/h3>\n

Plug the vehicle-side connector into the diagnostic port, then connect the 16-pin OBD2 side to the compatible diagnostic tool.<\/p>\n <\/article>\n

\n

Start Diagnostic Work<\/h3>\n

Operate the diagnostic tool according to the tool manual and the vehicle service procedure.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

\n
\n
Before You Order And Use<\/div>\n

Before You Order And Use<\/h2>\n

This is a physical adapter cable. Diagnostic success still depends on the vehicle, diagnostic tool, and supported communication protocol.<\/p>\n <\/div>\n

\n
\n

Check Pin Layout First<\/h3>\n

Confirm the vehicle diagnostic socket shape and pin count before ordering. Do not rely only on vehicle brand name.<\/p>\n <\/article>\n

\n

Not A Scanner<\/h3>\n

The cable only adapts the connection. It does not read codes, clear codes, or add functions without a compatible diagnostic tool.<\/p>\n <\/article>\n

\n

Protocol Support Depends On Tool<\/h3>\n

The connected diagnostic tool must support the target vehicle and protocol. The cable alone cannot guarantee communication.<\/p>\n <\/article>\n

\n

Avoid Excessive Pulling<\/h3>\n

Keep the cable relaxed during testing and avoid bending the connector sharply at the vehicle port.<\/p>\n <\/article>\n

\n

Keep Away From Heat<\/h3>\n

Do not route the cable near hot engine parts, moving belts, fans, or sharp metal edges during service.<\/p>\n <\/article>\n

\n

Confirm Before Purchase<\/h3>\n

If you are not sure whether your vehicle uses the matching GM 12-pin diagnostic port, contact support with a photo of the port.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

\n
\n
Warranty And Contact<\/div>\n

Warranty And Contact<\/h2>\n

Contact AUTOOL Store before ordering if you need help confirming connector type, vehicle fitment, diagnostic tool compatibility, or package contents.<\/p>\n <\/div>\n

\n
\n

Pre-Sales And Product Support<\/h3>\n

Send a clear photo of your vehicle diagnostic port and the diagnostic tool connector if you need confirmation before purchase.<\/p>\n
