No you can't. You can bypass a key or module, But the ECM still needs a signal to start and run the car.

Fault codes come from the fuel injection system diagnostic circuitry, which can store up to three faults. They can be read through the check engine light in the dash. You'll need to make a switched test lead with a spade connector on one end for connecting to the test connector. The other end is connected to ground. In 1992 the test connector is located beneath rear seat in sedan, or under the bellows ahead of shifter in convertible. With ignition off and test lead off, connect test lead to ground and test connector pin 2. turn ignition key to ON When Check Engine light comes on, turn test lead switch ON; Check Engine light should immediately go out When Check Engine light flashes ONCE, IMMEDIATELY turn test lead switch OFF Any fault codes will flash through the Check Engine light, with a long flash at beginning and end of each code; code flashes are short flashes, each block of flashes is separated by a longer space. With the engne OFF, the first fault code is that for "No RPM" 1 2 2 3 1, it will look like oooo x xx xx xxx x oooo where o = steady on, x = single flash There are over 20 fault codes, so get yourself a copy of the best source of info on this car: the "Bentley Bible" aka the Saab 900 Official Service Manual, costs about $40 from Amazon 16 valve manual: http://www.amazon.com/Saab-900-Valve-Service-Manual/dp/0837603137 8 valve manual :http://www.amazon.com/Eight-Official-Service-Manual-1981-1988/dp/0837603102 Hope this helps, if it does please give a "thumbs up", thanks Saabreur

I believe so. You need to draw more power to increase to bass.

side note. My system: Battery runs at 13.2 volts. When my Bass hits hard, the amp will cut into protection mode because it's getting less than 11.5 volts from the battery.

I reset and it works again and the battery will be back up to 13.2 volts.

Many of those radios had a secret code which could only be had thru the dealership. So- you had to take it to the dealer who pulled the radio and got one number then that would get you the secret code which you then wrote on the housing of the radio so you don't have to go thru this. Good luck with that.I just love classic foreign cars.

Or you could have a blown fuse. Under the hood drivers side.

The issue with starting systems is that there are many things that may be wrong with it. It certainly sounds like an electrical problem. I'm going to give you a way to check to see if it is actually the starter itself that may be bad. if you can physically reach the starter(on some you may not be able to) LIGHTLY tap on it with a hammer and then try to start it. DO NOT hit it very hard because this may cause the starter to become inoperable if it isn't already. if you turn the key and the batter just gets drained dead then I would sound to be a starter issue as well. These electrical issues are looked at by trained professionals in legal service shops.

As a licensed and certified mechanic I would highly recommend you have it tested before you start throwing parts at it because that may be VERY costly.and time consuming. when properly diagnosed you can save time, money, and a massive headache.

Hope this helps you out!

First, measure the voltage between the two battery posts with the engine not running. It should be near 12.6 volts. If it is around 10.5 to 11.0 volts, suspect a shorted cell in the battery. If it is around 11.5 to 12.0 volts, charge the battery at a slow rate for about half an hour. Next, measure the battery voltage again while the engine is running. It must be between 13.75 and 14.75 volts. If it is still around 12.0 volts, the alternator is not working. if it still has a problem check the wires from the alternator to the battery for green corrosion and loss connections.
