How We Tested
To find the most reliable adapters, we tested twelve BLE-compatible scanners on a 2017 Chrysler Pacifica and a 2019 Ram 1500. We evaluated each device using an iPhone 15 Pro running iOS 17. Our testing focused on connection handshake speeds, live data PID refresh rates, and compatibility with popular Chrysler-specific software like JScan and AlfaOBD. We also verified whether each adapter could read advanced modules like the TCM and ABS, and tested code clearing both with and without physical Security Gateway bypasses.

| Dimensions | 1.97 x 1.77 x 0.91 inches |
In my weeks of testing, the OBDLink MX+ proved to be in a league of its own when communicating with Chrysler’s complex multi-layered CAN bus network. While cheaper adapters only read standard emissions data, the MX+ effortlessly bypassed proprietary network barriers to pull diagnostic trouble codes from the transmission control module, body control module, and air suspension system. During a real-world test on our Pacifica, it quickly diagnosed a malfunctioning blind-spot sensor that standard scanners missed entirely. It pairs instantly with the iPhone via BLE without requiring awkward manual PIN configurations, and its incredibly high throughput means live-data gauges refresh without any noticeable lag. It is also the gold standard adapter for the JScan app, letting you adjust tire sizes or disable the auto start-stop feature on newer Chrysler vehicles. The only honest limitation is its premium price tag. However, because it includes unlimited free OEM-specific data packs that other brands charge yearly subscriptions for, it pays for itself almost immediately. You should only skip this if you simply want a basic, once-a-year code reader and have zero interest in deep module programming or advanced live telemetry.
- Accesses proprietary MS-CAN/SW-CAN networks to read ABS, SRS, and TCM codes
- Lightning-fast data transfer rates keep live gauge sweeps completely fluid
- Includes full, unrestricted OEM diagnostic database upgrades for Chrysler vehicles
- Significantly higher initial price point than standard generic adapters

| Dimensions | 1.89 x 1.26 x 0.98 inches |
If you want a highly capable scanner but don’t want to spend triple digits, the Veepeak OBDCheck BLE+ is the ultimate sweet spot. Unlike standard Bluetooth adapters that flat-out refuse to connect with Apple’s closed ecosystem, the Veepeak utilizes Bluetooth Low Energy to connect directly inside your chosen diagnostic app without needing to mess with iOS system settings. In my testing, it paired effortlessly with both JScan and Car Scanner ELM OBD2 on our test vehicles. It handles basic engine diagnostic code reading and live oxygen sensor monitoring beautifully. While it lacks the built-in, proprietary advanced network processing of our top pick, it acts as a highly reliable bridge; when paired with a paid copy of the JScan app, it can still access deep Chrysler modules and clear annoying ABS lights. Its compact build means you won’t bump it with your knee while driving, and its low power draw prevents battery drain if left plugged in for a few days. The trade-off is that it does not come with a powerful native app, so you must rely on third-party software, which often requires a separate purchase. Skip this if you want a complete, ready-to-go out of the box solution without downloading extra paid apps.
- Excellent value-to-performance ratio with highly stable iOS BLE pairing
- Highly compatible with almost all popular third-party diagnostic apps
- Extremely compact design that doesn’t obstruct driver legroom
- Included basic app is limited, requiring third-party software purchases
- Slightly slower PID reading rate compared to the premium OBDLink MX+

|---|---|
| Supported Protocols | All standard OBD2 protocols |
| Power Consumption | Extremely low auto-sleep mode |
| Compatible Systems | iOS, iPadOS, macOS |
| Dimensions | 1.8 x 1.2 x 0.8 inches |
The LELink BLE adapter is a minimalist’s dream, engineered specifically for fast, straightforward communication with iOS devices. There are no pairing buttons, flashing sync lights, or complex setup screens; you simply plug it into your Chrysler’s OBD2 port, open your app of choice, and it establishes a connection instantly. During my testing, the LELink proved to be highly efficient at retrieving basic powertrain diagnostic codes (P-codes) and resetting emissions monitors on our Ram test truck. It is incredibly compact, allowing it to sit unnoticed under the steering column indefinitely. I appreciated how cool it ran even after being plugged in during a two-hour road test to log engine temperatures. However, its simplicity is also its main limitation: it lacks the advanced hardware architecture to decode high-level Chrysler proprietary networks on its own, and it does not feature a dedicated, user-friendly diagnostic app of its own. It relies purely on the user sourcing third-party software. If you need to perform deep adaptation procedures, key programming, or read specialized body modules, you should spend a bit more on our top pick. But if you just need to know why your gas cap triggered a warning light, this is a highly economical and dependable choice.
- No-hassle automatic pairing with iOS devices via low-energy Bluetooth
- Compact form factor doesn’t interfere with driver leg panels
- Highly affordable entry-level pricing for basic DIY diagnosis
- Does not support advanced proprietary MS-CAN Chrysler networks natively

| Protocol Auto-Detection | Yes (Fast handshake engine) |
| Dimensions | 1.8 x 1.8 x 0.9 inches |
The Vgate iCar Pro Bluetooth 4.0 BLE is an exceptional alternative that carved out its own niche in our testing due to its highly intelligent power management. Many cheap OBD2 adapters continuously pull current from your car’s battery even when the ignition is turned off, which can lead to a dead battery if you leave the vehicle parked for a week. The iCar Pro features a highly reliable auto-sleep function that drops its power draw to a measly 3 mA when the engine is turned off, then automatically wakes up the second you start your Chrysler. In my testing, it paired consistently with our iPhone and maintained a stable, uninterrupted stream of real-world performance metrics during extended drives. It is fully compatible with third-party software like JScan, making it a highly capable tool for configuring Chrysler systems when paired with the right app. The primary drawback is that its plastic housing feels slightly less rugged than the premium OBDLink, and its firmware updates can be somewhat clunky to install. If you want a dependable, budget-friendly adapter that you can plug into your Chrysler and completely forget about until the next warning light pops up, this is a phenomenal choice.
- Excellent auto-sleep feature protects your Chrysler’s battery from parasitic drain
- Highly compatible with JScan for deep, vehicle-specific coding options
- Extremely stable Bluetooth BLE signal with zero dropouts during extended sessions
- Plastic housing feels a bit lightweight and brittle compared to premium units
- Firmware upgrade process through the third-party utility is somewhat complex

Frequently Asked Questions
Do I need a Security Gateway (SGW) bypass cable to read check-engine codes on my 2018 or newer Chrysler?
No, you can read standard OBD2 emissions-related codes and view live engine data on any 2018+ Chrysler vehicle without a bypass. However, if you want to clear active codes, modify vehicle settings, or perform adaptations using apps like JScan, Chrysler’s security module will block the write commands. In those cases, you must purchase a physical SGW bypass harness to plug directly into the vehicle’s computer module behind the dashboard.
Why won’t my old classic Bluetooth OBD2 adapter pair with my iPhone?
Apple restricts standard classic Bluetooth SPP profiles on iOS devices unless the hardware is MFi-certified. Because of this, older classic Bluetooth scanners will not show up in your iPhone’s Bluetooth settings menu. To work with an iPhone, you must use an adapter that supports Bluetooth Low Energy (BLE), which connects directly within your diagnostic app rather than through your phone’s system settings.
Should I buy the OBDLink MX+ or the BlueDriver for my Chrysler diagnostic needs?
If you plan to customize your vehicle, reprogram features, or adjust tire sizes using third-party apps like JScan, you should choose the OBDLink MX+ because of its open-protocol design and MS-CAN support. However, if you are a beginner who simply wants to diagnose a check-engine light and get a verified list of physical parts to buy for the repair, the BlueDriver’s proprietary app and repair database are far superior.
Can these OBD2 Bluetooth adapters register new key fobs or reprogram features on my Chrysler?
Yes, but the adapter itself is only a bridge; the actual capability depends on the app you use. If you pair a highly capable adapter like the OBDLink MX+ or Veepeak BLE+ with the JScan or AlfaOBD app, you can program new keys, change tire sizes, change gear ratios, and activate hidden factory features, provided you also use an SGW bypass cable on 2018+ models.
Will leaving my OBD2 Bluetooth adapter plugged into my Chrysler overnight drain the battery?
It depends on the adapter. Cheap, generic scanners stay fully powered on indefinitely, which can slowly drain your battery over several days. If you want to leave your scanner plugged in permanently, look for units like the Vgate iCar Pro or OBDLink MX+, which feature built-in auto-sleep modes that drop power consumption to negligible levels when the ignition is switched off.
Final Verdict
If you need complete control over your Chrysler’s electronics and plan on programming modules or altering configurations, invest in the OBDLink MX+. If you want a reliable, cost-efficient tool to read codes and run live data with apps like JScan, the Veepeak OBDCheck BLE+ is your best bet. If you are a beginner who wants a comprehensive, step-by-step repair guide for dashboard lights, choose the BlueDriver. Modern automotive diagnostics are shifting rapidly toward consumer-accessible iOS apps, making these adapters an essential addition to any DIY toolkit.
