Hondash obd bluetooth scanner
All Honda models (1992 — 2001 OBD1/2A/2B) that use the proprietary 3 pin or 5 pin DLC diagnostic connector are fully compatible and supported.
We encourage our customers to follow the compatibility guidelines prior to the item purchase, because of possible diagnostic connector differences between markets and model years. In case of United States / Canada market, the compatible 3 pin diagnostic connector was used only on OBD1 models (’92-’95), whereas the other markets (Europe, Japan, Australia, Brazil, Russia, etc. ) saw usage of 3 pin (5 pin on some Euopean models) on OBD1/2A/2B models (’91-’03).
Car models that use the 16 pin diagnostic connector, i.e. standard OBD2 socket (US/CA ’96-, others ’99-) are not supported at this moment.

How do I install Hondash scanner?
What is the device pairing PIN/password?
How to troubleshoot connectivity issues?
My car has only a 2 pin connector?
My 3 pin diagnostic connector has only two wires, it’s missing the middle one for power?
My 5 pin diagnostic connector does not have the 5th wire for communication?
Variants of OBD0 (’88-’91, some models until -’93) had only the 2 pin (SCS service check) connector for self-diagnostics purposes. It does NOT support diagnostics data transmission!
Some OBD1 models (’92-’95) don’t have any power source in DLC diagnostic connector (3 pin style connector with only two wires connected to it, middle pin and wire are missing). In this case you have to wire the scanner to a custom power source.
Some late (’99-’00) EU Accord/Civic models (OBD2 versions) had only the 2 pin (SCS service check) connector, versions with the 5 pin diagnostic connector did not have the communication wire connected to it, the 3 pin / 5 pin diagnostic connectors were superseded by the standard OBD2 16 pin port located under the steering wheel (or somewhere else under the dashboard).
Do I have to disconnect the scanner from the DLC diagnostic connector after finishing driving?
Won’t it drain battery?
You can leave the scanner connected. However if you’re not going to drive for a longer period (more than 2 weeks) it’s recommended to disconnect it to prevent possible battery drain even though the power consumption is very small, if you power the scanner directly from the DLC connector, which is hot at all times.
For permanent installation it’s recommended to use an ignition switched power source to power up the scanner.
What can Hondash do?
Can Hondash app display:
— Oil Temperature?
— Oil Pressure?
— AFR (Air to Fuel Ratio)?
— Fuel Level?
Hondash is still in active development and the feature set is not finalized yet, nonetheless, there is already a lot of functions and features as described on the App & Guides page.
- Oil Temperature — No, Honda engine does not have an oil temperature sensor
- Oil Pressure — No, Honda engine does not have an oil pressure sensor, only a pressure switch
- AFR — Air to Fuel Ratio — Yes, however the applied conversion of oxygen sensor voltage is based on a generic formula and not oxygen sensor manufacturer’s specific data, therefore it’s not guaranteed to be accurate and is intended for informational purposes only, you can however input your own calibration data following the guide for protocol configuration; to display AFR on Oxygen Sensor Parameter set «value of» to «Air Fuel Ratio» or «Lambda» instead of «Voltage» in the graph parameter assignment dialog (see gesture tutorial)
- Fuel level — No, the fuel level sending unit is not connected to the ECU
No, Hondash can read diagnostic trouble codes from the engine control unit only.
We recommend using the self-diagnostics procedure to obtain the codes from ABS/SRS control units, as described in the service manual.
The possibility of communication with the ABS/SRS control units via a Hondash scanner will be investigated some time in the future.
Why do some parameters read constant or zero values?
Why does the parameter Long Term Fuel Trim (O2FT-LT) show 0?
Parameters that do not change (keep reading arbitrary constant or zero values) are simply not supported by your ECU (e.g. some OBD1 ’92-’95 vehicles don’t support Fuel System Status FSS, Calculated Load Value CLV, Knock Sensor KS. ). Simply ignore those readings as they’re not relevant for your use case.
Long Term Fuel Trim (O2FT-LT) parameter reads 0 value on the majority of Honda vehicles from this era. The only explanation we can give you is simply that this is the way the engineers implemented the algorithm for calculating this parameter and it just returns 0 all the time, if the engine operates nominally.
Why does the fuel consumption show inaccurate values?
Why does the gear indication not match the currently selected gear?
Please follow the guide on Fuel consumption calibration and Gearbox calibration (section discussing gear detection range).
Currently no, but the app will receive an update to support it, ETA Q2 2024. However this will not be a replacement for the original Hondash scanner as the ELM327 supports only newer vehicles.
Yes, the app will support newer vehicles via 3rd party scanners such as the ELM327 scanner, ETA Q2 2024. A Hondash scanner for 16-pin OBD2 socket is currently in a pre-development stage; full product development pending, TBA.

I don’t have access to Google Play store, where can I get the Hondash app?
I can’t find the Hondash app on Google Play store?
My Android device reports that it is not compatible with the Hondash app?
Try to install the Hondash app from another source such as apkpure.com. The Google Play store sometimes incorrectly reports some devices as being incompatible.
Yes you can, however we don’t guarantee that it will 100% work. Very small percentage of models and manufacturers, usually the Chinese ones, have strict policies and allow only very specific devices to pair with their head units, or their Bluetooth communication implementation does not comply with the established Android SDK standards. Because our primary development platform is the smartphone we don’t offer any assistance regarding head units (brands inquiry, etc.).
No, however the support is being considered. Apple devices do not allow to use classic Bluetooth connection without the manufacturers of the product (us) enlisting to a special Apple’s MFi program, thus, the only feasible way to connect to Apple devices is to use much slower BLE (Low Energy) connection method, about 3x to 5x times slower than the classic Bluetooth version. We can 100% say now that communication with the Hondash app on any Apple product would run much slower than what is achievable on any Android device currently, even the cheap ones. No further details available at this moment.
Since Hondash works with Android versions as old as 4.4.4 (2013) we suggest buying a cheap used device (~€30) to work around this issue and use it as a dedicated device for Hondash.
The app requires one-time internet access when you use a Hondash scanner for the first time, or update the app, or clear the app data. Once the online check is complete you can continue using the app without an internet connection.
- yes, the app is free, if you use the official Hondash scanner, without any restrictions for the first activated user account; each unit is provided with one free user license, which the app will obtain automatically online and prompt you to activate your user account that you signed into; please be informed that you must claim the free license within 1 year since purchase date otherwise it will expire.
- additional user account activation will require purchasing a new user license; that is if you purchase a used Hondash scanner or want to use multiple user accounts you will be required to purchase a new user license (via in-app purchase, €9.99 excl. tax) to unlock the app on each additional user account

DLC diagnostic connector locations
The 3 pin DLC diagnostics data connector ( blue , older versions ’92-’95 may be grey or yellow ) is usually inserted in a protective rubber ( green or blue ) sleeve together with a 2 pin SCS connector (3 pin + 2 pin connectors in a single protective sleeve). The 2 pin connector is a SCS service check connector for self-diagnostics purposes, it does NOT support diagnostics data transmission.
