5-80 FI SYSTEM DIAGNOSIS
6) Disconnect the ECM coupler. (#5-37)
7) Check the continuity between W/G or W/Bl wire A and termi-
nal B, E.
8) Also, check the continuity between B/Br wire B and terminal
S.

! 09900-25008: Multi-circuit tester set

) Tester knob indication: Continuity test (()
Is the continuity OK?
9) After repairing the trouble, clear the DTC using SDS tool.
(#5-26)
Step 2
1) Connect the ECM coupler and HO2 sensor coupler.
2) Warm up the engine enough.
3) Measure the HO2 sensor output voltage between W/G or
W/Bl wire and B/Br wire, when idling condition.
$ HO2 sensor output voltage at idle speed:
0.4 V and less (+ W/G or W/Bl – - B/Br)
4) If OK, then pinch the PAIR hose 1 with a proper hose clamp.
5) Remove the fuel tank (#6-3) and frame head covers
(#9-6).
6) Measure the HO2 sensor output voltage while holding the
engine speed at 3 000 r/min.
$ HO2 sensor output voltage at 3 000 r/min:
0.6 V and more (+ W/G or W/Bl – - B/Br)
! 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
& Tester knob indication: Voltage (')
When using the multi-circuit tester, do not strongly
touch the terminal of the ECM coupler with a needle
pointed tester probe to prevent the terminal damage
or terminal bend.
YES Go to Step 2. (When indicating C44/P0130:)
NO
W/G or W/Bl wire shorted to ground, or W/G and
W/Bl or B/Br wire open.
