A 12) Check on compressor relay
Compressor relay has terminal arrangement as shown in the
figure.
A check on compressor relay should be made by applying
EB
12 volts to terminal S, grounding terminal A, and checking
if continuity exists between terminals C and D. Also, check
that continuity between terminals C and D does not exist
without applying
EB
12 volts to terminal B.

A13) Check on electric circuit
Electric circuit should be checked with a load (such as solenoid
valve and control unit) disconnected from the part in which
continuity is to be examined.
As for signal wires other than power lines, check continuity
and also check whether voltage is not applied to them and also
whether they are not grounded.
