Diagnosis Procedure
Regarding Wiring Diagram information, Automatic Drive Positioner Control Unit.
1. CHECK PEDAL ADJUSTING SENSOR SIGNAL
1. Turn ignition switch ON.
2. Select "PEDAL SEN" in "Data monitor" mode with CONSULT-III.
3. Check the pedal adjusting sensor signal under the following condition.





Is the value normal?
YES - Pedal adjusting circuit is OK.
NO - GO TO 2
2. CHECK PEDAL ADJUSTING SENSOR CIRCUIT HARNESS CONTINUITY





1. Disconnect automatic drive positioner control unit and pedal adjusting motor assembly.
2. Check continuity between automatic drive positioner connector
M33 (A), M34 (C) terminals 8, 33, 41 and pedal adjusting motor assembly connector E110 (B) terminals 3, 4, 5.

8 - 4 : Continuity should exist.
33 - 3 : Continuity should exist.
41 - 5 : Continuity should exist.

3. Check continuity between automatic drive positioner control unit connector M33 (A), M34 (C) terminals 8, 33, 41 and ground.

8 - Ground : Continuity should not exist.
33 - Ground : Continuity should not exist.
41 - Ground : Continuity should not exist.

Is the inspection result normal?
