Check Rear Lifting Sensor Circuit

1. CHECK REAR LIFTING SENSOR INPUT/OUTPUT SIGNAL 

   With CONSULT-II 

   Check operation with "LIFT RP PULSE" on the DATA MONITOR to make sure pulse changes.

   Monitor item [OPERATION or UNIT	Contents
   LIFT RR PULSE	The rear lifting position (pulse) judged from the rear lifting sensor is displayed.

   Without CONSULT-II 

   1. Turn ignition switch OFF.
   2. Check signal between driver seat control unit connector ground, with oscilloscope.

   OK or NG 

   OK: Rear lifting sensor circuit is OK.

   NG: GO TO 2.

2. CHECK REAR LIFTING SENSOR HARNESS CONTINUITY 

1. Disconnect driver seat control unit connector and rear lifting motor connector.
2. Check continuity between driver seat control unit connector B152 terminals 28C, 30 and rear lifting motor connector B162 terminals 28B, 30.

   28C (B/W) - 28B (B/W) : Continuity should exist. 

   30 (R/W) - 30 (R/W) : Continuity should exist. 

3. Check continuity between driver seat control unit connector B152 terminals 28C, 30 and ground.

   28C (B/W) - Ground : Continuity should not exist. 

   30 (R/W) - Ground : Continuity should not exist.
