Why do I sometimes see a label in ECU monitor but the data is null?

[Michel Castaño]

Sometimes ECUmonitor shows it is reading some specific information from the Onboard Computer

But data it is not arriving to rawdata:

You must check several things to identify the focus of the problem:

1. Check ECUmonitor activation. Command >QXAWA<. Answer should include the third byte in 1. Example>
>RXAWA00100000< Otherwise Activate it >SXAWA00100000<
2. Verify ECUmonitor status: >QXAEM0;+<. If answer is "D" Verify connection physically
3. Verify if a common value as well as RPM is present when it is queried directly to the unit (Ignition must be ON):

If there are values present, ECUmonitor its ok, so

4. Proceed to Check if the unit has configuration:

As shown in the image above unit has no Extended formats configured so eventually its configuration is possibly corrupted.

5. In case of memory corruption proceed with Configuration re-synchronization at:
Menu -> Devices -> [Select Device] -> Managed Configuration -> Set configuration


6. Otherwise, ECUmonitor could be configured to work in “Read Only Mode”. This can be verified with >QXAEML< command. 1 means active, 0 means Inactive.
