FI SYSTEM DIAGNOSIS 4-63
• Voltage
09900-25008: Multi circuit tester set
Tester knob indication: Voltage (
)
– Between W/R, B/R, W/B or Lbl wires and ground: approx. 0
V (When ignition switch is ON)
Is check result OK?
Step 2
ISC valve check
1) Remove the ISC valve. (
5-18)
2) Check the continuity between each ISC valve terminal and
ground.
09900-25008: Multi circuit tester set
Tester knob indication: Resistance (
)
ISC valve continuity:
(Infinity)
(Terminal – Ground)
3) If OK, measure the resistance (between the W/R wire termi-
nal
A
and B/R wire terminal
B
) and (between the W/B wire
terminal
C
and Lbl wire terminal
D
).
ISC valve resistance:
Approx. 20
at 20 °C (68 °F)
(Terminal:
A
– Terminal:
B
)
(Terminal:
C
– Terminal:
D
)
Is check result OK?
YES
Go to Step 2.
NO
Repair or replace the defective wire harness.
