Find the Power Steering pump. It should be at the front of the engine, on the driver's side (US Sidekicks, not a UK Vitara). It's got a pulley, and a fan-belt that drives it.
Right near it (you can follow the black hose from the steering pump) is a black, metal thing about the size of a pop-can, with a silver metal cap on it - it looks sort of like a little radiator cap. Push down and turn to open it - If I remember right, there's a dipstick inside the lid. ALSO: If I remember right, the Kick PS System uses AUTOMATIC Transmission Fluid. Top it off with generic ATF.

check if you have fuel and spark it needs both to work
On my 93 suzuki sidekick the check engine light came on at exactly 120000 miles.It can be reset if you take your drivers side speaker out you'll find a switch in there to reset it.If the problem occurs again then you probably have a real problem.If you vehicle is not running any different then I wouldn't be that concerned.
Usually a problem in the emission control system - have vehicle scanned to determine the problem
The reset switch is located just behind the dash at the driver's left knee. Remove the small rectangular center panel beneath the steering column (it pops out) and also the left side speaker assembly. You can reach the small switch from one side or the other, depending on who was running that operation on a given day at the assembly plant.
Check fuses Check bulbs
Try at least four, check the dipstick and see where you are from there. I have a '92 with a '98 engine and it uses four quarts.
check that the wire on the sylenoid is hooked up. also, check for clean connection to the battery terminals. I have one that looks clean but if it's not bright and shiny, it causes problems.
maybe your a/c has problems try to check the a/c maybe its time for maintenance or repair
get the CEL checked and fix the problem. Disconnecting the battery for 15 minutes will reset the light on an OBD1 vehicle.
The vin number should be located on the dashboard, drivers side, towards the left. It should be a long metal strip with the numbers engraved on it. If for some reason yours has been removed, check the title of the car or inside the door jams. Hope this helps...
place the Diagnostic jumper and read out the flashes. http://www.kick-fix.com/CEL/CEL.html this looks complex but it covers 89 to 95 FED and California cars. then post your DTC errors here. code 12 is normal , but you will have others. http://www.suzuki-forums.com/suzuki-sidekick-escudo-vitara-geo-tracker/
