Caution! When check the hydraulic unit solenoid relay and ABS motor, do not remove the brake hoses.
1. Check:
- Solenoid valve resistance (front)
Out of specification → Replace the hydraulic unit.
Solenoid valve resistance: 2.96-3.20Ω at 20°C (68°F)
a. Connect the pocket tester (Ωx1) to the solenoid valve (front) terminal as shown.
Pocket tester: 90890-03112.
Analog Pocket tester: YU-03112-C.
Positive tester probe → terminal «1»
Negative tester probe → terminal «2»
2. Check:
- Solenoid valve resistance (rear)
Out of specification → Replace the hydraulic unit.
Solenoid valve resistance: 2.96-3.20Ω at 20°C (68°F)
a. Connect the pocket tester (Ωx1) to the solenoid valve (rear) terminal as shown.
Pocket tester: 90890-03112.
Analog Pocket tester: YU-03112-C.
Positive tester probe → terminal «3»
Negative tester probe → terminal «4»
3. Check:
- ABS motor continuity
No continuity → Replace the hydraulic unit.
There is continuity.
a. Connect the pocket tester (Ωx1) to the ABS motor coupler terminal as shown.
Pocket tester: 90890-03112.
Analog Pocket tester: YU-03112-C.
Positive tester probe → terminal «1»
Negative tester probe → terminal «2»
