This is why it is important for someone who does not have a lot of automotive knowledge to not assume what a code means. Since there are hundreds of possible OBD codes, there are also hundreds of possible reasons for the light, including: Unfortunately, obvious and helpful vehicle symptoms do not always accompany an illuminated Check Engine Light.

OBD codes are most frequently referred to as OBD-II, which has been the code type since 1996. Tip: OBD codes refers to nearly the same thing as DTC codes, therefore you will often hear them used interchangeably in the automotive industry.

There are two acronyms to be aware of when it comes to discovering more about Check Engine Lights. While that sounds daunting, with a little patience, tackling basic diagnostics will give you useful knowledge about your vehicle and will also allow that Check Engine Light to do what it is really supposed to do: be your guide. There are literally hundreds of different codes a Check Engine Light can represent. By preparing yourself with a little automotive knowledge, a helpful tool, and general background information on what this light is actually trying to tell you, you will not only gain more peace of mind, you will also develop a closer relationship to your vehicle.ĭiagnostic trouble codes (DTC) are automotive computer codes stored by the on-board computer diagnostic system (OBD) in your vehicle. It can be quite intimidating to see that little light on your vehicle’s dashboard suddenly illuminate, but in reality, it is not something that should paralyze you in fear right away.

These include the ignition lock cylinder, Powertrain Control Module (PCM), Body Control Module (BCM), or Instrument Panel Cluster (IPC). Depending on the system, replacement of key components will necessitate that a relearn procedure be completed. If it doesn’t, there may still be something wrong with the system.Īfter the learn procedure is completed and the engine is running, the security light may stay on steady for a few minutes and then go off-this is normal. After turning the ignition off for the third time and waiting for twenty seconds, the engine should start and run.

You will now begin the thirty-minute relearn procedure, which is just the ten-minute procedure repeated three times. If you get the same result as previously-nothing happens or the engine starts and dies with the security light flashing-wait ten more minutes. If it starts and runs, everything is okay. When it does, turn the ignition off, wait twenty seconds, and then try to start the engine. The flashing light should go off or illuminate without flashing. Leave the key in the On position and wait ten minutes. If nothing happens or the engine starts and dies, the security light will be flashing. The ten-minute procedure involves trying to start the engine. Which one you use depends on the system and what components have been replaced. The Passlock system has two basic relearn procedures-a ten-minute procedure and a thirty-minute procedure. If you have 2 keys and it does not start, try this procedure. If it does not start with the second key or you do not have one, you may be able to take the key itself to the dealer to see if it is actually transmitting properly.

If it starts, then the first key is bad and has to be replaced. When inserted into the ignition, the alarm system looks for codes from the key. Your anti-theft system (pass-lock) may have a fault or it may be the key itself.
