#16 pin aldl connector serial#
To make the Serial Data Link available at an affordable cost I have produced a USB-SDL interface that can be used with a PC or laptop, please go to The latest dealer tool is the Denso manufactured SDT, however that tool has no support for Suzuki's SDL. There was also a Carman tool available but information on this is limited. The Tech 1A was replaced as the dealer tool by the Tech2, Suzuki cartridges for these are available through eBay but are most likely to be cloned, a prospective purchaser would need to check which models are supported. Tech 1/1A cartridges can also be used in the Vetronix/Bosch Mastertech MTS3100 tool which also has a lot of extra functionality. Made the original Suzuki dealer tools, the Tech1 and the Tech 1A. The SDL is bi-directional one wire interface, there are few hand held scan tools available and these are intended for dealer use and cost thousands of dollars new. Will use the KWP2000 protocol rather than the SDL protocol. If pin 7 is also populated then the main engine ECU Power for a scan tool is provided with 12V on pin 16 and ground on pin 5. The J1962 connector has the SDL on pin 9, this pin is reserved by the OBD2 specification for the manufacturers own use. The ALDL connector is common on early models and has the SDL on pin M, Pins H and A provide 12V power and ground for a scan tool. There are two different connectors used, a 12-pin ALDL style connector and a 16-pin J1962
In documentation for early models but is sometimes shown on the schematic. This interface is very rarely referred to If there are no codes, fuel injection system probably okay. Cant remember off the top of my head but a quick Googlesearch will help. 2) If you are running OBDI, you can pull codes by jumping two pins. The Serial Data Link is a diagnostic interface that allows fault codes and real time data to read from the ECU. If it lights you know there is fuel in the crankcase.
