5. If the malfunction remains, the control module must be replaced.
6. Control modules are sensitive to electrostatic discharges. Great care must be taken to follow the following procedure to avoid damaging internal
components in the control module:
-
Keep the control module in its packaging for as long as possible.
-
Never touch the pins of a control module with your hands or clothing.
-

Checking For Open Circuits/Short Circuits
Checking For Open Circuits/Short Circuits
General
Use a suitable instrument such as a multimeter.
An ohmmeter must not be used for testing components containing semi-conductors, e.g. control modules and time delay relays, etc.
The power supply to the system being resistance tested must be disconnected because the instrument will apply a low measuring current to the circuit.
This will ensure that there is no current already present in the circuit so that a reliable reading can be obtained.
