Examination
1. (Models up to 1996, models since 1996 (ZS-T)).
Check the conductivity of the relay windings.
A) Check for continuity between terminals "5" And "6" socket A.
b) Check for continuity between terminals "4" (positive ohmmeter probe) and 6" (negative ohmmeter probe) connector A and the absence of conductivity - when the ohmmeter probes are connected back.
Note: observe the polarity when connecting the ohmmeter probes.
V) Check for continuity between terminals "4" (positive ohmmeter probe) And "5" (negative ohmmeter probe) connector A and the absence of conductivity - when the ohmmeter probes are connected back.
G) (ZS-T)
Check for continuity between terminals "2" And "5" A.D connector) (ZS-T)
Check for continuity between terminals 1" connector A and "3" socket B.
e) (ZS-T)
Check for continuity between terminals "1" And "2" socket B.
and) (ZS-T)
Check for continuity between terminals "3" And "4" socket B.
If the conditions are not met, replace the relay.
2. (Models up to 1996)
Check the operation of the solenoid valve relay.
A) Apply battery voltage to terminal "1" connector A and output "W" socket B.
b) Check for continuity between leads "2" And "5" connector A, and in the absence of conductivity between the terminals "5" And "6" socket A.
3. (Models since 1996 (4S-FE, 3S-FE)) Check the operation of the solenoid valve relay.
A) Check for continuity between terminals "1" And "3" relay connector.
b) Check for continuity between leads "2" And "3" relay connector.
V) Check for continuity between leads "4" And "b" relay connector.
G) Check for continuity between terminals "5" (positive ohmmeter probe) And "3" (negative ohmmeter probe) relay connector and lack of conductivity - when the ohmmeter probes are connected back.
d) Apply voltage to terminals "4" And "6" relay connector and check for continuity between the terminals "1" And "3", and the absence of conductivity between the terminals "2" And "3".
3. (Models up to 1996)
Check the operation of the electric pump relay.
A) Apply battery voltage to terminals "3" And "4" socket B.
b) Check for continuity between leads "1" And "2" socket B.
4. (Models since 1996 (4S-FE, 3S-FE)) Check the operation of the electric pump relay.
A) Check for continuity between terminals "1" And "2" relay connector.
b) Check for continuity between terminals "3" And "4" relay connector.
V) Apply battery voltage to terminals "W" And "4" and make sure there is continuity between the pins "1" And "2".
