B1905 Sensor Power Supply Fault - Component Inspection

Component Inspection

1. Ignition "OFF"
2. Disconnect front height sensor connector and rear height sensor connector.
3. Check that sensor connector power supply is within the specification after turning IG KEY "ON".
4. Connect front height sensor connector and front height sensor connector.
5. Measure the voltage of power circuit of each sensor with all connector connected.

Specification : Output voltage is not changed When front height sensor, rear height sensor connecting.
(If the change of sensor power supply occur as connecting sensor connector, this means the occurrence of short inside of sensor.)





* REFERENCE*
Perform the initializing after replace "Height sensor"
* Vehicle condition
(1) Park at lever land.
(2) Vehicle speed ≤ 5 km/h.
(3) Engine r.p.m > 500 rpm.
(4) Connect scan-tool.
(5) CAN communication is normal status.
(6) Battery voltage > 10.5 V.
(7) Headlamp S/W ON, AFLS ON.
