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 DoorTester 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.

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 |
