B2117 ADJ PEDAL MOTOR
B2117 ADJ PEDAL MOTOR
DescriptionINFOID:0000000005147462
• The pedal adjusting motor is installed to the pedal assembly.
• The pedal adjusting motor is activated with the automatic drive positioner control unit.
• The pedal assembly is adjusted forward/backward by changing the rotation direction of pedal adjustingmotor.
DTC LogicINFOID:0000000005147463
DTC DETECTION LOGIC
DTC CONFIRMATION PROCEDURE
1. STEP 1
Turn ignition switch ON.
>> GO TO 2
2. STEP 2
Check “Self diagnostic result” with CONSULT-III.
Is the DTC detected?
YES >> Perform diagnosis procedure. Refer to ADP-36, "DiagnosisProcedure".
NO >> Inspection End.
Diagnosis ProcedureINFOID:0000000005147464
Regarding Wiring Diagram information, refer to ADP-138, "Wiring Diagram".
1. CHECK PEDAL ADJUSTING MECHANISM
Check the following.
• Operation malfunction caused by pedal adjusting mechanism deformation or pinched harness or other for- eign materials
• Operation malfunction and interference wit h 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 “ADJ PEDAL MOTOR” in "Active test" mode with CONSULT-III.
Is the inspection result normal?
YES >> Pedal adjusting motor circuit is OK.
DTC No. Trouble diagnosis
name DTC detecting condition
Possible cause
B2117 ADJ PEDAL MOTOR When any manual or automatic operations are not
performed, if motor operation is detected for 0.1
second or more, status is judged "Output error". • Harness and connectors
(pedal adjusting motor circuit is
opened/shorted, pedal adjusting
motor power supp ly circuit is
opened/shorted.)
• Pedal adjusting motor
Test item Description
ADJ PEDAL MOTOR The pedal adjusting motor is activated by receiving the drive signal.

3. CHECK PEDAL ADJUSTING MOTOR CIRCUIT HARNESS CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect automatic drive positioner control unit and pedal adjusting motor.
3. Check continuity between automatic drive positioner control unit
connector M34 (A) terminals 37, 45 and pedal adjusting motor
connector E109 (B) terminals 1, 2.
4. Check continuity between automat ic drive positioner control unit
connector M34 (A) terminals 37, 45 and ground.
Is the inspection result normal?
YES >> GO TO 4
NO >> Repair or replace harness.
4. CHECK AUTOMATIC DRIVE POSITION ER 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.
Is the inspection result normal?
YES >> Replace pedal adjusting motor assembly. Refer to ADP-178, "Removal and Installation".
NO >> GO TO 5
5. CHECK INTERMITTENT INCIDENT
Refer to GI-38, "
Intermittent Incident".
Is the inspection result normal?
YES >> Replace automatic drive posit ioner control unit. Refer to ADP-175, "Removal and Installation".
NO >> Repair or replace the malfunctioning part. 37 - 1
: Continuity should exist.
45 - 2 : Continuity should exist.
37 - Ground : Continuity should not exist.
45 - Ground : Continuity should not exist.

DRIVER SEAT CONTROL UNIT
NOTE:
The front seat LH position and pedal adjustment functions (see the following table) operate simultaneously in
the order of priority.
*: In conjunction with sliding the seat, the door mirrors are positioned.
CANCEL OF FAIL-SAFE MODE
The mode is cancelled when the A/T selector lever is shifted to P position from any other position.
DTC IndexINFOID:0000000005147579
*1:
• 0: Current malfunction is present
• 1-39: Displayed if any previous malfunction is present when current condition is normal. The numeral value increases by one at each
IGN ON to OFF cycle from 1 to 39. The counter remains at 39 even if the number of cycles exceeds it. However, the counter is re set
to 1 if any malfunction is detected again, the normal operation is resumed and the ignition switch is turned from OFF to ON. OPERATED PORTION
