Hi ,

We have Air compressor ( engine driven), when we start running the compressor , we found amber light with display ” ECU 7009 protect Lamp”.

In the trouble shoot manual doesn’t specify about this code. What might be the problem.

Compressor type is ” XAHS447 / XAHS950CD7 “

Any advise?

Did you see/read this?



Only possible when engine is running or if
Diagnostics Mode is active.
Access the ECU DM1 LIST menu via Alarm View.
In case of ECU RED LAMP:
Do NOT acknowledge the ECU RED LAMP alarm.
DM1 alarms are automatically copied into the
Alarm View, and can be read there.
For all ECU triggered alarms, the respective SPN code
is shown in the ECU DM1 LIST
A full list of supported SPN codes is provided by the
