Ask Pulse · Beta

A mechanic's second opinion, right in your pocket.

A code like P0420 doesn't tell you much on its own. After Read Codes, Pulse reads the whole scan and gives you a verdict, the reason and what to do next. Or just ask it about a code, a noise or a warning light.

Safe to Drive
Nothing to fix now
Drive With Care
Mechanic within a few days
Stop Driving
Mechanic or tow now
Why, in plain English
One to three sentences on how your codes connect, not a dictionary entry for each one.
What to do next
Up to three next steps, down to which codes to give your mechanic.
Ask about anything
A fault code, a noise, a warning light. Pulse checks which car you mean first: the same symptom has different causes on different engines.
It can run the scan
When a scan would help, Pulse asks to run it right in the chat. Nothing starts until you tap, and the results go straight to Pulse.

Ask Pulse is in beta and can make mistakes. Every account gets a weekly Ask Pulse session; Pro gets more.

Read Codes · Free

Scan every module, not just the engine.

Read Codes goes through every control module OBDPulse knows for your car (engine, transmission, ABS, airbags, climate, driver assistance and more), or just the ones you pick. Every fault is grouped by the module that reported it, with a plain description of the code.

Scan HistoryNEW

Every scan you run, on every car, is kept with your account, even after you remove the car. Open the full report of any past scan and share it as a PDF. Free shows your last 7 scans; Pro shows them all.

Questions? Answers.

What is OBDPulse?+
OBDPulse turns your phone into an OBD2 scan tool. Paired with a Bluetooth Low Energy (BLE) OBD2 adapter, it reads and clears fault codes, shows live sensor data, checks emissions readiness, runs service resets and manufacturer procedures, and keeps a report of every scan. Ask Pulse, its AI assistant, explains what it finds.
What is Ask Pulse?+
Ask Pulse is the AI assistant in OBDPulse, currently in beta. After a Read Codes scan it gives a verdict (Safe to Drive, Drive With Care or Stop Driving), explains why in plain English and lists up to three next steps. You can also chat with it about a code, a noise or a warning light, and it can ask to run a scan for you. It can make mistakes, so treat it as a second opinion, not a replacement for a mechanic.
Is Ask Pulse free?+
Yes. Every account gets an Ask Pulse session that renews each week. Pro gives you a bigger weekly session.
Can Ask Pulse change anything on my car by itself?+
No. Pulse can suggest a scan, but nothing runs until you tap it. Before it can clear codes, a Read Codes scan has to have run in the same chat, and you confirm before anything is cleared.
What can I do for free?+
Read Codes, Read VIN and Live Data (five parameters at a time) are free, along with a weekly Ask Pulse session and your last 7 scans in Scan History. Pro unlocks Clear Codes, Freeze Frame, O2 Sensor, Mode 6, Smog Check, Track Mode, Service Reset, Control Functions, Terminal, every Live Data parameter, your full Scan History, workshop details on reports and more Ask Pulse.
What vehicles are supported?+
OBDPulse supports most vehicles built after 1996 (USA), 2001 (petrol, EU) and 2004 (diesel, EU). If your vehicle has an OBD-II port, it is most likely compatible. Which modules Read Codes can reach, and which Control Functions are available, depend on your car's make.
Which cars does Service Reset work on?+
Volkswagen group, Hyundai and Kia cars, and Triumph motorcycles. It resets the service reminder after an oil change or inspection, and the app confirms with the vehicle once the reset is done.
Do I need any hardware?+
Yes, you'll need a Bluetooth Low Energy (BLE) OBD-II adapter. OBDPulse does not support Bluetooth Classic adapters.
Can I cancel anytime?+
Yes, you can cancel anytime from your Google Play or App Store account settings. You'll keep Pro until the end of the billing period.
My app isn't connecting. What should I do?+
Make sure your ignition is on, the adapter is BLE-compatible and properly plugged in, and Bluetooth and location permissions are enabled. Then restart the app and try again. Still stuck? Email support@obdpulse.com.
