READ VALUE USING INTELLIGENT TESTER (PBD POWER BACK DOOR SENSOR)
INSPECT POWER BACK DOOR SENSOR ASSEMBLY
CHECK HARNESS AND CONNECTOR (POWER BACK DOOR SENSOR ASSEMBLY - POWER BACK DOOR UNIT ASSEMBLY [POWER BACK DOOR ECU] AND BODY GROUND)
POWER BACK DOOR SYSTEM - Power Back Door Sensor Circuit
DESCRIPTION
When the power back door unit assembly (power back door ECU) receives a jam signal from the power back door sensor while the power back door closer is operating, the power back door unit assembly (power back door ECU) reverses the back door operation and opens the door.

INSPECTION PROCEDURE
| 1.READ VALUE USING INTELLIGENT TESTER (PBD POWER BACK DOOR SENSOR) |
Check the Data List for proper functioning of the power back door sensor ().
Back Door| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| PBD power back door sensor (Left) | Power back door sensor LH signal / ON, OFF or Open | ON: Power back door sensor LH pressed
OFF: Power back door sensor LH not pressed
Open: Power back door sensor LH circuit open | - |
| PBD power back door sensor (Right) | Power back door sensor RH signal / ON, OFF or Open | ON: Power back door sensor RH pressed
OFF: Power back door sensor RH not pressed
Open: Power back door sensor RH circuit open | - |
- OK:
- The display is as specified in the normal condition.
| OK | |
| |
| PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE ()

|
| 2.INSPECT POWER BACK DOOR SENSOR ASSEMBLY |
Remove the power back door sensor assembly ().
Inspect the power back door sensor assembly ().
Result| Result | Proceed to |
| OK | A |
| NG (for LH) | B |
| NG (for RH) | C |
| | REPLACE POWER BACK DOOR SENSOR ASSEMBLY LH ()
|
|
|
| | REPLACE POWER BACK DOOR SENSOR ASSEMBLY RH ()
|

|
| 3.CHECK HARNESS AND CONNECTOR (POWER BACK DOOR SENSOR ASSEMBLY - POWER BACK DOOR UNIT ASSEMBLY [POWER BACK DOOR ECU] AND BODY GROUND) |
for LH:
Disconnect the S24 power back door sensor assembly LH connector.
Disconnect the L52 power back door unit assembly connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| S24-1 (OSL) - L52-15 (OSL) | Always | Below 1 Ω |
| S24-2 (OSLE) - L52-14 (OSE) | Always | Below 1 Ω |
| S24-1 (OSL) - Body ground | Always | 10 kΩ or higher |
| S24-2 (OSLE) - Body ground | Always | 10 kΩ or higher |
for RH:
Disconnect the S23 power back door sensor assembly RH connector.
Disconnect the L52 power back door unit assembly connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| S23-1 (OSR) - L52-13 (OSR) | Always | Below 1 Ω |
| S23-2 (OSRE) - L52-14 (OSE) | Always | Below 1 Ω |
| S23-1 (OSR) - Body ground | Always | 10 kΩ or higher |
| S23-2 (OSRE) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| OK | |
