Is the check engine light on your vehicle showing up and you're not sure why? Use ECRI’s DTC shooting feature. No unlock code is needed for this feature.

1) Plug ECRI device into OBD Port

2) Launch App

3) Bluetooth will connect automatically

4) Tap DTC setting 

5) ECRI will immediately start a dealer level scan on your vehicle to find codes.

6) When the scan is finished, tap any module to clear codes on that module.

In order for ECRI to give you the most accurate speedometer reading possible; here are some tips we highly recommend using for accurately measuring your tire size before recalibrating your vehicle.

  1. Locate the center of your hub/wheel
  2. From your hub measure to the ground.
  3. Multiply that value by 2

X = Center of the hub to the ground

X * 2 = Rolling diameter that we need to use for calibration

The reason we need to measure this way is to account for a couple different factors that will make the tire size shorter than the size stamped on the tire. First: most tire manufacturers make tires that are slightly shorter than the advertised size. Second: the weight of the vehicle on the tire will compress the tire to make it shorter still. Overall, we’ve found that the rolling diameter is usually around an inch shorter than the size stamped on the sidewall of most tires, which would mean a speedometer that is off by about 3-percent!

  • Bluetooth needs to be enabled on the device and for the app (iOS & Android). Android: ECRI needs location permissions to scan for the device.
  • If "ECRI" on the device is lit red, it is discoverable and awaiting connection.
  • If "ECRI" on the device is lit green, the app is connected.
  • If the device is not lit, unplug and plug back in.
  • The device powers off after 30 seconds without connection. This prevents excess battery drain and provides a layer of security to prevent unintended access to your vehicle.
  • The tire size entered is the size on the sidewall and it needs to be reduced (typically 1") to account for tire "squish" from weight of vehicle.
  • The settings are not taking effect (see support item below about this).

JL/JT Models can require a longer "off" period after programming. If this is happening, do the following after programming:

  • Turn ignition off
  • Open the driver door
  • Exit the vehicle with the keyfob
  • Close the driver door
  • Wait at least 5 minutes to ensure all modules power down

  • This ensures all modules power down. When modules power back up, they check with other modules on the vehicle for new settings and self-update at that time.

    On the JK, the speedometer can stop working if a module on the vehicle doesn't update properly during programming.  This can be caused by:

    1. The key not being in the on position with the engine off during programming
    2. Turning the key off during or quickly after programming
    3. Not turning the key off after programming before starting the engine
    4. Bad luck by trying to program when the Jeep is doing internal regular updates.

    Luckily the fix is easy:

    1. Clear the codes in the DTC tab by tapping on the codes
    2. Cycle Ignition off then back on without starting the engine
    3. Program a size that is at least 1/2" different than the current value
    4. Cycle Ignition off then back on without starting the engine
    5. Program the correct size
    6. Cycle Ignition off then back on without starting the engine
