Step 4
1) Measure the resistance between 5 terminal and ground at
the ABS control unit coupler.
$ Normal value: ∞ Ω (Infinity)
) Tester knob indication: Resistance (Ω)
Is the resistance between 5 and ground OK?
YES Go to step 6.
NO Go to step 5.
Step 5
1) Measure the resistance between 1 terminal and ground at
the front wheel speed sensor coupler.
$ Normal value: ∞ Ω (Infinity)
) Tester knob indication: Resistance (Ω)
Is the resistance between 1 and ground OK?
YES Inspect the wire harness. (Faulty B/R wire)
NO Faulty front wheel speed sensor
Step 6
1) Check for continuity between F terminal on the ABS control
unit coupler and 2 terminal on the front wheel speed sensor
coupler.
$ Normal value: Continuity (*)
+ Tester knob indication: Continuity test (*)
Is there continuity between F and 2?
YES Go to step 7.
NO Inspect the wire harness. (Faulty W/R wire)
Step 7
1) Check for continuity between 5 terminal on the ABS control
unit coupler and 1 terminal on the front wheel speed sensor
coupler.
$ Normal value: Continuity (*)
+ Tester knob indication: Continuity test (*)
Is there continuity between 5 and 1?
YES Go to step 8.
NO Inspect the wire harness. (Faulty B/R wire)
