BR-54flowchartDiagnostic Procedure 7
Diagnostic Procedure 7 — actuator solenoid resistance
1
INSPECTION START — Remove battery negative terminal connector.
2
[A] CHECK SOLENOID VALVE RESISTANCE. Disconnect control unit connector. Check resistance between control unit connector (vehicle side) terminals. Flashing number 1: terminals ㉜ and ②. Flashing number 2: terminals ㉜ and ㉟. Flashing number 3 or 4: terminals ㉜ and ⑱. Resistance: 0.7 - 1.6 Ω.
O.K.
Replace control unit.
N.G.
3
[B] Disconnect actuator connector. Check resistance between actuator connector (actuator side) terminals. Flashing number 1: terminals ⑥ and ①. Flashing number 2: terminals ⑥ and ②. Flashing number 3 or 4: terminals ⑥ and ③. Resistance: 0.7 - 1.6 Ω.
N.G.
Replace actuator.
O.K.
4
Repair harness between actuator connector and control unit connector.
