Suzuki vehicles 1986-95 obd1 code retrieval
To get the
check engine light codes of Suzuki vehicles is fairly easy. All you need is to
access the fuse panel under the dash on the driver’s side. On the lower left
corner of the fuse panel, there is a fuse holder or diagnostic connector that
you have to install a fuse. Once you do that and after you turn the key on, the
dash panel will start flashing the codes.
To clear
the codes, turn the key off and remove the fuse. Then disconnect the battery
negative terminal for 30 seconds and reconnect. (On some models, the duration
of disconnection is up to 60 seconds, check your manual or contact ATS).
To read the
codes being flashed, use this as a guide: code 13 is one long flash followed by
3 short flashes. Each code is repeated 3 times before going to the next code
after a pause. When you see the codes flashing in the dash panel, write it down
and reset the codes. You can do this by disconnecting the battery negative
terminal for 1-2 minutes and reconnect. Start and warmed up the engine and
repeat self dianostic procedure shown above. If the fault codes show up again,
then that is the one you have to fix.
