DTC "43" (C1643): Wheel speed sensor circuit short (F)
POSSIBLE CAUSE
• Poor contact on the front wheel speed sensor coupler
• Faulty front wheel speed sensor, etc.
Step 1
1) Turn the ignition switch to OFF.
2) Remove the left frame cover. (!GSF1200K6/SK6 9D-5)
3) Remove the fuse box mounting bolt. (!Page 28)
4) Check the ABS control unit coupler for loose or poor con-
tacts. If OK, then disconnect the ABS control unit coupler.
5) Check for continuity between 3 (W/R) and B (B/R) at the
coupler.
" 09900-25008: Multi-circuit tester set
( Tester knob indication: Continuity ())
Is there continuity between 3 and B?
Inspect the wire harness. (Faulty sensor wire)
YES
Faulty front wheel speed sensor
NO Go to step 2.
Step 2
1) Check for continuity between 2 (B/Y) and 3 (W/R) at the
coupler.
( Tester knob indication: Continuity ())
Is there continuity between 2 and 3?
Inspect the wire harness. (Faulty sensor wire)
YES
Faulty wheel speed sensor
NO Go to step 3.
Step 3
1) Turn the ignition switch to ON with the ABS control unit cou-
pler disconnected, measure the voltage between 3 (W/R)
and N (B/W) at the coupler.
% Normal value: 0 V
& Tester knob indication: Voltage (')
Is the voltage between 3 and N normal value?
YES Replace the ABS control unit/HU.
Inspect the wire harness. (Faulty sensor signal or
NO
power supply wire)
