If it was professional installation, we suggest you take the unit back and get them to find / fix the issues ( they may be able to re-pin a bad connection in the plug)
You need to check all connections are tight as vibrations can cause connections to become loose.
Main areas that would cause this are
Check all connections are solid (by manually bouncing/wriggling them quite vigorously) this needs to be done at the connection point not the plug. If any connections are loose, he needs to tighten them up.
Check the earth connection and ensure it is in solid contact with bare metal and that the main battery earth is connected properly.
It would also be a good idea to check that no wires have been damaged or kinked.
If the above dose not find a solution, isolate the loom (by holding the loom tightly so it can’t move about 3” front the plug/control unit) and first test again by moving the whole unit.
If this causes the issue, check all wires are secure in the plug by pushing then into the connector.
If a replacement unit is needed, you will need to re-wire the entire setup without cutting and joining any wiring. If you are able to locate the exact cause, then it may avoid the need to replace anything. To isolate the part that needs replacing.
As a general rule on any Davies, Craig digital switches/controller with below issues:
Check the ignition location, if it is connected to the ignition coil or another source that has a reasonable load on it could be the cause.
A simple test for this it to connect the ignition wire directly to battery positive, if it operates correctly then they need to relocate the ignition to an ignition switched source like the accessories.
PLEASE MAKE SURE you DO NOT cut the Sensor / Probe wiring to shorten or extend while installing. This action interferes with the resistance signal to the control box and subsequently an 'err' message will appear.
The switch will be completely useless and not serviceable if you cut the wiring.
We suggest you wind up the wiring should you need a shorter the lead.
