READ VALUE USING INTELLIGENT TESTER (LOCK POSITION SWITCH)
INSPECT FRONT DOOR WITH MOTOR LOCK ASSEMBLY (DRIVER SIDE)
CHECK WIRE HARNESS (DOOR LOCK - ECU)
POWER DOOR LOCK CONTROL SYSTEM - Only Driver Door LOCK / UNLOCK Functions do not Operate |
DESCRIPTION
The main body ECU receives lock / unlock switch signals and activates the door lock motor accordingly.WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.READ VALUE USING INTELLIGENT TESTER (LOCK POSITION SWITCH) |
Use the Data List to check if the door lock is functioning properly.
Main body ECU Item Measurement Item / Display (Range) Normal Condition Diagnostic Note D-Door Lock Pos SW Driver side door lock position switch signal ON / OFF ON: Driver side door is unlocked
OFF: Driver side door is locked- - OK:
- When the door lock is operating, the intelligent tester should display as shown in the table.

| 2.INSPECT FRONT DOOR WITH MOTOR LOCK ASSEMBLY (DRIVER SIDE) |
for LHD:
Apply the battery voltage to the motor terminals and check the operation of the door lock motor.
- OK:
Measurement Condition Specified Condition Battery positive (+) → 4 (L)
Battery negative (-) → 1 (UL)Lock Battery positive (+) → 1 (UL)
Battery negative (-) → 4 (L)Unlock
Measure the resistance of the position switch.
- Standard resistance:
Tester Connection Switch Condition Specified Condition 8 (LSSR) - 7 (E) Lock 10 kΩ or higher 8 (LSSR) - 7 (E) Unlock Below 1 Ω
 |
for RHD (w/o Double Locking System):
Apply the battery voltage to the motor terminals and check the operation of the door lock motor.
- OK:
Measurement Condition Specified Condition Battery positive (+) → 4 (L)
Battery negative (-) → 1 (UL)Lock Battery positive (+) → 1 (UL)
Battery negative (-) → 4 (L)Unlock
Measure the resistance of the position switch.
- Standard resistance:
Tester Connection Switch Condition Specified Condition 7 (LSSR) - 8 (E) Lock 10 kΩ or higher 7 (LSSR) - 8 (E) Unlock Below 1 Ω
 |
for RHD (w/ Double Locking System):
Apply the battery voltage to the motor terminals and check the operation of the door lock motor.
- OK:
Measurement Condition Specified Condition Battery positive (+) → 2 (L)
Battery negative (-) → 1 (UL)Lock Battery positive (+) → 1 (UL)
Battery negative (-) → 2 (L)Unlock
Measure the resistance of the position switch.
- Standard resistance:
Tester Connection Switch Condition Specified Condition 7 (LSSR) - 8 (E) Lock 10 kΩ or higher 7 (LSSR) - 8 (E) Unlock Below 1 Ω

- Standard resistance:
Tester Connection Specified Condition H5-1 (UL) - IH-9 (ACT-) Below 1 Ω H5-4 (L) - IH-8 (ACT+) Below 1 Ω H5-8 (LSSR) - E18-25 (LSWD) Below 1 Ω H5-7 (E) - Body ground Below 1 Ω
for RHD (w/o Double Locking System):
Disconnect the G5 door lock connector.
Disconnect the E18 ECU connector.
Disconnect the IH junction block connector.
Measure the resistance of the wire harness side connectors.
- Standard resistance:
Tester Connection Specified Condition G5-1 (UL) - IH-18 (ACT-) Below 1 Ω G5-4 (L) - IH-17 (ACT+) Below 1 Ω G5-7 (LSSR) - E18-25 (LSWD) Below 1 Ω G5-8 (E) - Body ground Below 1 Ω
for RHD (w/ Double Locking System):
Disconnect the G5 door lock connector.
Disconnect the E18 ECU connector.
Disconnect the IH junction block connector.
Measure the resistance of the wire harness side connectors.
- Standard resistance:
Tester Connection Specified Condition G5-1 (UL) - IH-18 (ACT-) Below 1 Ω G5-2 (L) - IH-17 (ACT+) Below 1 Ω G5-7 (LSSR) - E18-25 (LSWD) Below 1 Ω G5-8 (E) - Body ground Below 1 Ω
