Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK PEDAL ADJUSTING MECHANISM 

   Check the following.

   • Operation malfunction caused by pedal adjusting mechanism deformation or pinched harness or other foreign materials
   • Operation malfunction and interference with other parts by poor installation

     Is the inspection result normal? 

     YES: GO TO 2

     NO: Repair or replace the malfunctioning part and check again.

2. CHECK FUNCTION 
   1. Turn ignition switch ON.
   2. Check "PEDAL MOTOR" in "Active test" mode with CONSULT.

      Test item	Description
      PEDAL MOTOR	The pedal adjusting motor is activated by receiving the drive signal.

      Is the inspection result normal? 

      YES: Pedal adjusting motor assembly circuit is OK.

      NO: GO TO 3

3. CHECK PEDAL ADJUSTING MOTOR ASSEMBLY CIRCUIT HARNESS CONTINUITY 
   1. Turn ignition switch OFF.
   2. Disconnect automatic drive positioner control unit and pedal adjusting motor assembly.
   3. Check continuity between automatic drive positioner control unit connector M34 (A) terminals 37, 45 and pedal adjusting motor assembly connector E109 (B) terminals 1, 2.

      37 - 1: Continuity should exist. 

      45 - 2: Continuity should exist. 

   4. Check continuity between automatic drive positioner control unit connector M34 (A) terminals 37, 45 and ground.

      37 - Ground: Continuity should not exist. 

      45 - Ground: Continuity should not exist.

      Is the inspection result normal? 

      YES: GO TO 4

      NO: Repair or replace harness.

4. CHECK AUTOMATIC DRIVE POSITIONER CONTROL UNIT OUTPUT SIGNAL 
   1. Connect the automatic drive positioner control unit and pedal adjusting motor assembly.
   2. Check voltage between automatic drive positioner control unit connector and ground.

      Connector	Terminals		Condition	Voltage (V) (Approx.)
      	(+)	(-)
      M34	37	Ground	Pedal adjusting switch ON (FORWARD operation)	Battery voltage
      			Other than above	0
      	45		Pedal adjusting switch ON (BACKWARD operation)	Battery voltage
      			Other than above	0

      Is the inspection result normal? 

      YES: Replace pedal adjusting motor assembly. Refer to "REMOVAL AND INSTALLATION ".

      NO: GO TO 5

5. CHECK INTERMITTENT INCIDENT 

   Refer to "INTERMITTENT INCIDENT ".

   Is the inspection result normal? 

   YES: Replace automatic drive positioner control unit. Refer to "REMOVAL AND INSTALLATION ".

   NO: Repair or replace the malfunctioning part.
