1994 Buick Regal Custom has the 12 pin OBD1 connector. This
connector is missing the B (diagnostic pin). All other pins are there.
I was hoping to be able to jumper this to clear the SES history, and
also to use as a diagnostic tool, because jumpering the pin to ground
activates a lot of solenoids for troubleshooting purposes.
It looks as though the pin was intentionally left out...
Is there a workaround for this problem....???
(I already have an xray scan tool which does not clear SES codes and can't
afford a tech1
for home car repair use).
Thanking you in advance...
