As the codes for the check engine light flicker, take note. Then look up the code descriptions in your repair handbook to determine the precise problem.
For instance:
- Check engine codes 0 and 16 indicate problems with the Electronic Control Unit (ECU) and fuel injectors, respectively, if you have a Honda.
- If you own a Nissan, error code 22 and code 31 both point to fuel pump issues.
Let’s examine the alternative approach, which does not require a DTC scanner or engine code reader.

independent diagnostic tool
It is simple and quick to read out the error memory using a standalone diagnostic equipment. Just like a pro, you simply insert the connecting cable into the BMW’s OBD2 socket, and the device displays the diagnostic codes. Typically, a diagnostic tool is a suitable weight and useful size.
The drawback in this situation might be the need to first purchase an appropriate diagnostic tool. They are typically available online for less than $100. But not every diagnostic tool is compatible with every BMW.
Be cautious! A product’s low cost does not always imply that it is high quality. particularly for BMW diagnostic equipment. Extremely cheap devices should be handled with extra caution because they can be fake. These frequently have problems or can only be utilized in conjunction with expensive, specialized software that must be bought.
the use of an odometer
Another method for getting the OBD2 codes is to use the odometer. The user must depress the odometer button on the car. (The “travel” and “reset” buttons also need to be reset.) The car’s ignition key must be switched on and off simultaneously. When the procedure is finished, the ignition key must be turned on. Then, the odometer’s “reset” and “travel” buttons must be disengaged. The codes will then be visible on the digital odometer’s display. The issue with your car will be displayed on the screen.
As Simple As 1-2-3
You’ll need a pen and paper, jumping wires, a paperclip without a plastic exterior, and the repair handbook. Without starting the engine, turn the ignition on and off a few times, then end with the key in the on position.
Then, your automobile will look for any previously stored error codes. Until one light—typically the “service engine” light—remains on, all of the dash’s lights should turn on. Be on the lookout now as this box’s light begins to blink.
The difference between each pulse and the subsequent number that will pulse constitutes a break. A “0” will typically be represented by rapid flashing. For instance, the symbol for “20” is pulse, pulse, pause, flashing. Note these codes, then look them up in your service manual to find out what they indicate. These frequently display your current odometer reading, and occasionally the code appears without even pulsating!
Without OBD, can I read codes?
Anyone with knowledge of how to read an e39 98’s codes without an obd? With my e34, there was a pedal/ignition trick. Is there a comparable product for the e39 models? Links???
Not at all necessary. The best tool for most people is a Peake tool that can read codes and reset your Oilchange and Inspection indicators. The cheapest option is a simple Reader from Autozone.
How does it function? I wanted to learn how the BMW program operates because I have a comparable program for other automakers.
If it works, that seems like a good setup. Anyone have information on how well this system performs in comparison to the peak? Does the peak provide real-time information and statistics to aid in deciphering codes and problems?
A code reader and reset tool, the peak. It costs around one-fourth as much as the least expensive OBD II Scan tool. The cheapest OBD II scanners cost between $450 and $500. The other devices you see are all typically code readers only, some of which may have marginally better functionality or programming but do not offer live scanner data. The BMW inspection timers cannot be reset by the majority of OBD scanners.
Where can I get my BMW code?

Can I operate a BMW with the check engine light on?
A constant glow normally denotes something less serious, but a check engine light that flashes suggests your car’s engine is seriously damaged and needs quick repair. We strongly advise not operating your BMW while the check engine light is flashing and setting up BMW servicing right away.
Without a code reader, how can I verify the code on my engine?
Except for one, generally the service engine light, all of the dash lights will go out immediately after they illuminate.
If the engine light codes appear on the odometer, make a note of each error code. Most modern cars or cars with the OBDII system can be repaired using this technique.
However, if your check engine or service engine light starts to pulse or flash instead of the odometer display, your car is OBD1. And your fault code is the flash that the engine light produces.
How do you interpret the code? It can be challenging to read a code from a check engine light blink.
Each engine light pulse corresponds to a digit, and the pause between pulses shows how far off the digits are from one another. A brief engine light flash serves as the representation for a zero.

Can I use my phone to scan my OBD2?
Although the majority of Android scan tools support all five protocols, this does not mean that every device is compatible with them. But why use an Android scan tool? There are numerous advantages to this:
- Android is seen as a universal platform, much like Windows for the PC, thanks to its plug-and-play characteristics. Both Bluetooth and Wi-Fi OBD2 scanners can be used with Android smartphones and tablets. We are all aware that Apple and iOS are Bluetooth-incompatible and can only be utilized with Wi-Fi wireless OBD2 scanners. Why? We can all blame Apple for this because of their stringent wifi and sharing restrictions.
- The popularity (or market share/dominance) of Android versus iOS is a hotly contested topic. According to a recent survey from 2015, Apple had a staggering 44% of smartphone subscribers, outpacing the combined subscribers who purchased Android-powered handsets from Samsung, LG, Motorola, and HTC. However, Android is still widely used in the US and is far more prevalent abroad. Worldwide Android shipments in 2003 totaled 70.1%, vs just 21% for iOS. There are no valid arguments as to why Android Bluetooth scan tools are still in demand today.
- As we’ve already noted, the great selection of OBD apps available on Google Play makes it feasible for OBD2 scan tools for Android to be incredibly simple to use. You can use certain free apps, but in order to access all of the in-app features, much like the majority of Play Store games, you must purchase the paid version of the app.
