With "RECLN SW-FR, RECLN SW-RR" on the DATA MONITOR, operate the reclining switch to check ON/OFF operation.

Fig 1: CONSULT-II Display - DATA MONITOR

Without CONSULT-II 

1. Turn ignition switch OFF.
2. Check voltage between driver seat control unit connector and ground.

OK or NG 

OK : Reclining switch circuit is OK.

NG : GO TO 2.

1. Disconnect driver seat control unit and power seat switch LH.
2. Check continuity between driver seat control unit connector P2 terminals 12, 27 and power seat switch LH connector P8 terminals 9, 10.

   12 - 9 : Continuity should exist. 

   27 - 10 : Continuity should exist. 

3. Check continuity between driver seat control unit connector P2 terminals 12, 27 and ground.

   12 - Ground : Continuity should not exist. 

   27 - Ground : Continuity should not exist.
