DIAGNOSTICS CHART WITH SELECT MONITOR
Step
1 CHECK RESISTANCE OF VALVE RELAY.
1) Turn ignition switch to OFF.
2) Remove valve relay from relay box.
3) Measure resistance between valve relay
terminals.
Terminals
No. 85 — No. 86:
Is the measured value within the specified
range?
2 CHECK CONTACT POINT OF VALVE RE-
LAY.
1) Connect battery to valve relay terminals
No. 85 and No. 86.
2) Measure resistance between valve relay
terminals.
Terminals
No. 30 — No. 87:
Is the measured value less than the speci-
fied value?
3 CHECK CONTACT POINT OF VALVE RE-
LAY.
Measure resistance between valve relay termi-
nals.
Terminals
No. 30 — No. 87a:
Does the measured value exceed the specified
value?
4 CHECK CONTACT POINT OF VALVE RE-
LAY.
1) Disconnect battery from valve relay termi-
nals.
2) Measure resistance between valve relay
terminals.
Terminals
No. 30 — No. 87:
Does the measured value exceed the spec-
ified value?
5 CHECK CONTACT POINT OF VALVE RE-
LAY.
Measure resistance between valve relay termi-
nals.
Terminals
No. 30 — No. 87a:
Is the measured value less than the specified
value?
6 CHECK SHORT OF VALVE RELAY.
Measure resistance between valve relay termi-
nals.
Terminals
No. 86 — No. 87:
No. 86 — No. 87a:
Does the measured value exceed the specified
value?
