I have a 94 Tracker.  CEL is on.  It still runs fine.  I was trying to check the code and see what it's throwing, but can't get it to flash. 

This is the connector I found under the hood.  Is this the right one? (white plug)


This is what's under my dash beside the fuse box.


Any input?  I tried jumping 2 and 3 on the white plug and then turning the key on.  Do you turn it to Acc, or all the way to ON. Acc gave me nothing.  When all the way to ON, it just came on and stayed on, which IIRC is what it always does, like when you get ready to start the vehicle.

I also found this switch recently.  Wasn't sure what it was.  After searching, it seems it may be the CEL switch?  If so, what exactly does it do when you flip it?  Just turn the light off, or what?  It was under the dash, kinda right behind the speaker on the driver's side.


Any input is greatly appreciated.

In order for the light to flash the check engine light must be off. Switch that switch you are pointing to in the picture then try again 

Gotcha.  So switch it off, then jump pins 2 and 3 on the white connector?  I assume that's the right one.  What are the connectors under the dash??  Anyone know?

that is for those people who have those million dollar snap on readers that read obd1's also. sidekicksrock is right on the money as i just had to flick the switch on my 93 to read my trouble codes.

A new question in line with the old one. Where do you find what the flashes mean? And which one of those ports would you plug a reader into? I am thinking it is the gray one, or is that the grey one?

the gray one

here you go.--------------------------------------------------------------------------------
I have tried to list every possible Suzuki engine that might be found in one of our vehicles, if you note a wrong code please let me know and a reference where you found the correct code and I'll get it changed. To the best of my research ability, these are correct.

86–95 Samurai, Swift & 89 Sidekick
NOTE: This information does not apply to carberated engines, as they will have a check engine light but don't store codes, so you have to troubleshoot manually to determine which sensor is causing the problem.
DTCs may be accessed by installing a spare fuse into the fuse box diagnostic terminal, located under the LH side of the instrument panel, then turning the ignition On.
90–95 Sidekick
DTCs may be accessed by installing a jumper wire between diagnostic check connector terminals B and C, located in the RH rear of the engine compartment, then turning the ignition On.
96–00
Accessing DTCs must be done through the Data Link Connector (DLC), located under the LH side of the instrument panel, using a Suzuki (Tech-1) scan tool or an OBD II generic scan tool.
Reading trouble codes
The instrument panel Check Engine lamp displays the DTCs. In normal operation the lamp will light when the ignition is turned On. However, two different lamp functions can occur when the engine is started. The lamp may turn off immediately, indicating there is no fault at that time, or stay lit, informing the vehicle operator that there is a system failure. If the lamp stays lit a DTC will be stored in the ECM memory. When a DTC is accessed from the ECM memory the Check Engine lamp will flash in a series, indicating the DTC number. When multiple system failures occur applicable DTCs will be indicated three times each. DTCs will continue to flash as long as the ignition is On, and the diagnostic switch terminals are grounded.
Clearing Codes
DTCs may be erased by disconnecting and isolating the battery ground cable for more than 60 seconds, or after 50 key cycles if the malfunction has not recurred.
On models with OBD II, the DTCs may be cleared with the scan tool, following the tool manufacturer’s instructions.

Thanks for the info. Another question on the flashes. Will it flash for the first number, pause, and then flash for the second number or will it flash fifty eleven times and I have to try counting all the flashes?

it should flash one after another and then start over and do it again and continue to do it until you turn the key off.
