2. Check lifting sensor (rear) signal under the following conditions.
*1: The value at the seat position attained when the battery is connected is considered to be 32768.
Is the indication normal?
YES >> Lifting sensor (rear) function is OK.
NO >> Refer to ADP-66, "
DiagnosisProcedure".
Diagnosis ProcedureINFOID:0000000003759172
1.CHECK LIFTING SENSOR (REAR) SIGNAL
1. Turn ignition switch ON.
2. Read voltage signal between lifting motor (rear) harness connector and ground with oscilloscope.
