DTC "45" (C1645): Wheel speed sensor circuit open (R)
POSSIBLE CAUSE
• Poor contact on the rear wheel speed sensor coupler
• Faulty rear wheel speed sensor, etc.
Step 1
1) Turn the ignition switch to OFF.
2) Remove the frame covers, left and right.
(!GSF1200K6/SK6 9D-5)
3) Remove the fuse box mounting bolt. (!Page 28)
4) Check the ABS control unit coupler and rear wheel speed
sensor coupler for loose or poor contacts. If OK, then discon-
nect the ABS control unit coupler.
5) Measure the resistance between 2 (B/Y) and ground at the
ABS control unit coupler.
% Normal value: ∞ Ω (Infinity)
" 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
* Tester knob indication: Resistance (Ω)
Is the resistance between 2 and ground OK?
YES Go to step 3.
NO Go to step 2.
Step 2
1) Disconnect the rear wheel speed sensor coupler.
2) Measure the resistance between A (Black) and ground at
the rear wheel speed sensor coupler.
% Normal value: ∞ Ω (Infinity)
* Tester knob indication: Resistance (Ω)
Is the resistance between A and ground OK?
YES Inspect the wire harness. (Faulty B/Y wire)
NO Replace the rear wheel speed sensor.
Step 3
1) Measure the resistance between H (W/Y) and ground at the
ABS control unit coupler.
% Normal value: ∞ Ω (Infinity)
* Tester knob indication: Resistance (Ω)
Is the resistance between H and ground OK?
YES Go to step 5.
NO Go to step 4.
