IF you are installing a REMOTE STARTER with KEYLESS ENTRY you MUST USE the INTERFACE BYPASS MODULE, Part # DB-ALL or XK09, EITHER Bypass will do the Anti-theft and Keyless entry. If connecting a keyless entry only you can use the GMDL-BP. NOTE #2: The IGNITION #2 wire WHITE must be connected to prevent a CHECK ENGINE LIGHT from turning on and to prevent DAMAGE to the TRANSMISSION on this Vehicle. NOTE #3; The BCM is located under the Drivers Side of the dash, the BCM has 6 plugs on it, with the PURPLE plug on the back. NOTE #4: On BASE model truck the DOOR LOCK INTERFACE MODULE is not necessary, the LOCK wire is a LT BLUE (TYPE B) @ the BCM, LT BLUE PLUG, PIN B5, and the UNLOCK wire is a WHITE (TYPE B) @ the BCM, LT BLUE PLUG, PIN B10. NOTE #5: On BASE Model trucks, the Door Trigger wires are @ the BCM, LT BLUE PLUG, PINS B4 and A5. On 4-Door Trucks the LEFT REAR Door is a LT BLUE/BLACK (-) PIN A3 and the RIGHT REAR Door is a LT GREEN/BLACK (-) PIN A2, located in a PURPLE PLUG at the BCM, use all 4 wires and diode isolate when installing an alarm system.

The security light illuminates when that signal gets broken, or not seen at all. When the communication breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. (like it thinks it's being hot wired) The car shuts down because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. It will either turn off the starter, or the fuel injectors. The vehicle may run for 2-3 seconds before shutting down. This link explains it pretty well.

Do It Yourself GM Security bypass

On a 2003 Chevy Maibu the theft system light comes on and blinks when the system is triggered. The car will not start and the fuel pump cuts out. You must turn key to on and have all doors closed. Keep the key to on for 10 mins til theft light turns solid and then disappears. Then turn key to start and it should fire up.

Hi there, the Common Rail Diesel Inyection (CRDI) 2000 cc 112 Hp M/T have a big trouble on cluth plate, and sounds very loud between 1500 and 2000 rpm on 2,3,4 shift.That motor has too much torque and cause excesive wear in the cluth roll and plate so starts roominess in the cluth system. You could change those parts but quickly the sounds come again. Hyundai is the resposable of that damage. I hope in the near future recall the CRDI model 112 Hp and replace the cluth.

Bypass the immobilizer system. You'll need the wiring diagram. Go to http://www.hmaservice.com/ and register. After you do this, you'll have access to manuals, service bulletins, wiring diagrams, etc.about your vehicle.

The Chrysler factory VTSS vehicle theft security system will do just that. Try unlocking the vehicle with the remote or one of the three VTSS switches, both front doors or the rear hatch. Sometimes the door switches get damaged front "Slim Jimming" the lock. The rear hatch switch is usually intact. The VTSS should "Arm" after a battery disconnect or dead battery. The VTSS cannot be bypassed once it is activated. If you put a previously installed ECM that was on a vehicle with VTSS, on a vehicle without VTSS the vehicle will not run.

disconnect the alarm horn in the r/h side of your boot lock on lock the vehicle with the key in d/s door the vehicle should start then but ya need to buy a new key fob soon price around 100 euro

check cluth fliud level

If it is leaking fluid inside the car, It sounds like to me you have a leaking clutch master cyl, if so replace and bleed system.
