Revision: 2005 July 2005 FX
8. CHECK GROUND CIRCUIT (AUTOMATIC DRIVE POSITIONER CONTROL UNIT)
Check continuity between the automatic drive positioner control unit
connector M50 terminal 40, 48 and ground.
OK or NG
OK >> Driver seat control unit circuit is OK.
NG >> Repair or replace harness between automatic drive positioner control unit and ground.
CONSULT-II Function (AUTO DRIVE POS.)AIS002YF
CONSULT-II can display each diagnostic item using the diagnostic test modes shown following.
*1: For setting automatic drive positioner functions only.
*2: Refer to BL-38, "
Data Monitor" .
*3: During vehicle driving, do not perform active test.
CONSULT-II INSPECTION PROCEDURE
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Turn ignition switch “OFF”.
2. Connect “CONSULT-II” and “CONSULT-II CONVERTER” to the data link connector.
3. Turn ignition switch “ON”. 40 (B) – Ground : Continuity should exist.
48 (B) – Ground : Continuity should exist.
