Inspection Procedure

1. Check for DTC B2223. DTC B2223 indicates a pulse sensor malfunction.
   1. Without code outputs, proceed to A.
   2. With code outputs, proceed to B.

1. B: GO TO  DTC B2223 POWER SLIDE DOOR PULSE SENSOR MALFUNCTION ON REAR RIGHT DOOR  
2. A: Go to next step 

1. Check for foreign objects on the sliding area.

1. NG: REMOVE OBSTACLES AND RE-CHECK SLIDE OPERATION 
2. OK: Go to next step 

1. Turn OFF* the power slide door main switch in order to locate the area where reverse operation has been triggered.

   *OFF is a condition that orange paint on the top of the switch does not appear.

2. Move the slide door manually, and check to make sure no obstacles are present (no extra resistance) around the reverse operation area and that the slide door smoothly operates.

1. NG: ADJUST FITTING CONDITION OF SLIDE DOOR (See  ADJUSTMENT  ) 
2. OK: Go to next step 

1. Using the hand-held tester, check the DATA LIST for proper functioning of power slide door touch sensor RH.

1. OK: Go to step   5 
2. NG: Go to next step 

1. Inspect the resistance of the sensor.

1. NG: REPLACE POWER SLIDE DOOR TOUCH SENSOR RH 
2. OK: Go to next step 

1. Disconnect the P32 sensor and the P27 ECU connectors.
2. Check the resistance between the wire harness side connectors.

   Standard (Check for open circuit):

1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 
2. OK: REPLACE POWER SLIDE DOOR ECU RH 

1. Select the ACTIVE TEST and then check that the power slide door control motor and clutch RH operates.

HINT:

During the ACTIVE TEST, the hand-held tester sends a signal to the power slide door ECU RH to drive the motor and clutch. If the motor and clutch operates, the motor and clutch itself and the wire harness between the motor and clutch and the power slide door ECU are considered to be functioning normally.

Standard (Power slide door ECU RH): 

1. OK: REPLACE POWER SLIDE DOOR ECU RH 
2. NG: Go to next step 

1. Remove the motor and clutch.
2. Connect the battery positive (+) lead to terminal 3 and battery negative (-) terminal lead to terminal 2.
3. Apply battery voltage to the terminals and check the motor operation.

   Standard:

4. Check the resistance of the clutch terminals.

   Standard: 

   CLUTCH TERMINALS RESISTANCE SPECIFICATIONS
   
   

   Terminal No.	Specified Condition
   2 - 3	4.0 Ω
   6 - Body ground	Below 1 Ω

5. Reinstall the motor and clutch with the connector connected.

6. Check the pulse of the pulse sensor.
   1. Using an oscilloscope, check the pulse generated when the door is manually opened and closed.

   Standard (Reference): 

HINT:

A cycle of the pulse changes between approx. 10 to 20 msec. according to the speeds that the slide door is moving.

1. NG: REPLACE SLIDE DOOR CONTROL MOTOR & CLUTCH ASSY RH 
2. OK: Go to next step 

1. Disconnect the P22 motor and clutch, the P27 and P28 ECU connectors.
2. Check the resistance between the wire harness side connectors.

   Standard (Check for open circuit):
