Malfunction Codes Explained
Code P: Power Compliance Malfunction
How is it triggered?
The Engine synchronization compliance malfunction will appear when the vehicle has moved for more than 30 cumulative minutes during the last 24 hours with the Engine syncronization data diagnostic error active. This Malfunction is an accumulation of engine synchronization data diagnostic events.
How to clear it?
This is cleared automatically when the amount of engine synchronization data diagnostic events is less than 30 minutes in the last 24 hours. So this malfunction takes 24 hours to clear once the movement of the truck stops.
Things to check
Check if the connection of the device and the truck is solid and that the battery of the truck is working. If the problem persists, you may need to replace the device.
Code E: Engine Synchronization Compliance Malfunction
How is it triggered?
The Engine synchronization compliance malfunction will appear when the vehicle has moved for more than 30 cumulative minutes during the last 24 hours with the Engine syncronization data diagnostic error active. This Malfunction is an accumulation of engine synchronization data diagnostic events.
How to clear it?
This event is cleared automatically when the amount of engine synchronization data diagnostic events is less than 30 minutes in the last 24 hours. As such, once present, this malfunction takes 24hrs to clear once the movement of the truck stops.
Things to check/verify
Check engine gauges and the LED of the device to assure that the vehicle is compatible with the device. Two blinks on the LED indicate that the device is not able to establish communications with the vehicle.
Check if the engine gauges are updating correctly and in regular intervals, without jumps and if the data matches the vehicle instruments.
Check that the device is firmly locked on the diag. connector or well fixed on the truck dashboard. Make sure the vehicle is not parked near sources of vibration which can cause false accelerometer reads.
Code T: Timing Compliance Malfunction
How is it triggered?
This occurs when the EZ-ELD device is not able to initialize its internal clock at startup. The built-in clock is initialized by either the GPS or by the phone’s clock.
How to clear it?
The error is cleared automatically once the clock is initialized.
Things to check/verify
Check GPS reception. Make sure the LED is not blinking once, and use the extension cable to place the device in a more favorable position. Make sure that the phone is connected correctly to the device.
Code L: Positioning Compliance Malfunction
How is it triggered?
This occurs when the vehicle moves for more than 5 miles without a GPS position in a 24 hour period.
How to clear it?
The error is cleared automatically when the vehicle recovers a valid GPS position. Please note that this is a 24 hr window and as such it can take 24 hrs for this error to be cleared AFTER a valid GPS position is obtained.
Things to check/verify
Check GPS reception using the track and trace function. Make sure the LED is not blinking once, and use the extension cable to place the device in a more favorable position. Make sure that the phone GPS is enabled.
Code R: Data Record Compliance Malfunction
How is it triggered?
This indicates that the memory available to the EZ-ELD App in the user’s phone or tablet is full.
How to clear it?
Delete content to free the smart device memory. At least 5% of the phone/tablet memory needs to be available for the App to run. Then logout and login again using the EZ ELD App to fix the error.
Things to check/verify
Check the available memory on the phone. If there is not enough available to run the App, delete content to free up memory. Then logout and login using the EZ ELD App.
Code S: Data Transfer Compliance Malfunction
How is it triggered?
This occurs after three consecutive data transfer data diagnostic events. For instance, 3 consecutive days without communicating with the main EZ-ELD server.
How to clear it?
The error will be cleared when the ELD device connects to the central EZ-ELD servers during the next login process.
Things to check/verify
This issue occurs when the phone indicates a valid internet connection, but the internet is not actually working. This can happen when the data plan was fully consumed, is expired or not responding. It can also occur if the EZ-ELD servers are not functioning.
Things to try: use airplane mode to force the app into offline operation, connect to Wifi, test the web browser of the phone to verify the internet is working correctly.
Code O: Other ELD Detected Malfunction
How is it triggered?
Not caused by the EZ ELD system. A legal requirement for us to feature additional Manufacturer specific / custom error codes.
