Diagnose 'check engine' warning alarm

Hi
Are you sure that's not a 'safety feature' to warn others that you're reversing - like on commercial trucks?

Also, why do you let it warm up for 10-15 mins? Seems excessive? Is this suggested in the Owner's Manual for that engine? As this is surely fuel injected, it should be ready to go immediately....or wait ~5 minutes if you're going full throttle from the dock/launch...to let the oil warm a bit.

with engine on, check lights, main beam and dip and side lights. Check tail lights work too.
With lights on, turn the indicator switch left for a few seconds then right. You are looking for odd behavior with lights.
It's a good indication of an earthing fault (grounding).
Turn engine off and see if lights-on warning alarm sounds.
Corrosion around connectors often causes light faults, check them all, if they seem sound then check the relays.
Another possibility is the switch itself. Wiggle it around very gently feeling for loose movement or flickering lights. The whole switch may need replacing. It's a start......after that then you need to check wiring loom. (very rarely the bulb is the fault so test them with a circuit tester)

P0703 Suzuki - Brake Switch Circuit Malfunction
Possible causes
- Faulty Brake Switch
- Misadjusted Brake Switch
- Brake Switch harness is open or shorted
- Brake Switch circuit poor electrical connection
Check if the stop light works with the brake pedal, if the brake lights are inoperative, replaced or adjust the brake switch.
Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Brake lights inoperative

dependent upon your state restrictions it needs to be either fixed or taken through a waiver process. in most any state that does smogs anything after 1996 with an engine light on will fail smog because it only comes on to warn you of an emissions related issue.
I would suggest having it diagnosed at the nearest 2G smog certified shop...

the warning light with the padlock on shows that your car immobilizer is active. Need a specialist to re program your immobilizer.

check teh oil light pressure switch on the engine they often have a rubber boot over the wiring connections ,these boots tends to fill with oil throwing the oil light switch on ,must be a american market one because i have never seen this buzzer on the europeon ones

sounds like the brake light switch is the culprit for both the intermittent brake lights and cruise control problems. the engine warning light could be an unrelated issue that needs to be diagnosed.

Yes it does have a low fuel warning light. Mostly when you have 10 liters remaining in your tank.
