About this app

ALDL Scan is an app for viewing ALDL data from 1995 and older GM vehicles. It can be used to view Analog parameters, Malfunction codes, or resetting the vehicle's ECM. ALDL Scan also provides for the recording of ALDL data to the user's Android device. ALDL Scan must be used in conjunction with the Bluetooth car adapter from 1320 Electronics. ALDL Scan is not compatible with other Bluetooth car adapters.

I hope you haven't given up no this app. It is having issues now. I put in the protocol and it bumps out bluetooth. If I put the bluetooth adapter first it bumps out the protocol. I love this. I bought your bluetooth device in 2016 and used it up till now. It bumps out 1 or the other. I could send you a short video clip to show you if needed. Thanks for what you do!

Worked for 6 uses then a pop-up window that" line 7 can't be read". So I uninstalled/reinstall only to have same result? Went into app and deleted files and cache, then uninstall/reinstall. Same thing "line 7 unreadable" Emailed developer, at least 5 days ago never responded. If it works , great information to help tune. I'm just up against a wall with app continuous loop. Ok just heard from John Wales not receiving email, checked my sent email from this google play store the "r" was dropped. So I will recontact. So I reinstalled app and its working remembering previous settings? For whatever reason app is not uninstalling which is probably android8 on my phone.

Hello Mr. Beaulieu. I just checked and haven't received a recent message from you. Last message discussed the GPS speed vs ECM speed. I suspect that you may be using the second button on the main screen to select a protocol file. The preinstalled protocols haven't change recently. Can you send me a screen shot from your main screen? Thank you.

this app was well written and is a credit to the author. However it connected ok via B/T but showed empty fields, or simply put no data. in all fairness it's probably due to myself not being clued in properly when it comes to the app. but a ALDL Cable works fine, I'd just love to access real time data on my 1997 VT 5L Commodore.

Hello James. Are you using the app with one of our ALDL Bluetooth adapters? I suspect maybe you are using an ELM327 adapter. The ELM327 style adapters will not communicate at the 8192 serial baud rate required by your ECM. The ELM327 adapters support the OBD2 protocols only.

What's new

Added various new ALDL protocols. A094 protocol was revised.
