(1) Measure the resistance between terminals 1 and 2 or
3 and 4.
Standard value: 245 at
(2) A too small resistance indicates a short and a
too large resistance indicates an open circuit.
In either case, replace the ‘pulse generator assemb ly.

In either case, replace the assembly.
(3) Connect a
battery between the terminal and body
of each solenoid valve and check the operating soun d.
The valve is okay if an operating sound is heard. No
operating sound indicates that the valve is stickin g or
has accumulated foreign matter. In this case, repla ce
