(1) Move the back door lock assembly to the lock position. | | *1 | Latch | *a | Component without harness connected (Back Door Lock Assembly (Back Door Courtesy Switch)) | *b | Lock | *c | Unlock | | |
(2) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
1 (ACT-) - 3 (D+) | Lock | 10 kΩ or higher |
(3) Apply battery voltage to the door lock motor and check the operation of the door lock motor.
OK:
Tester Connection | Condition | Specified Condition |
2 (ACT+) - 1 (ACT-) | Battery positive (+) → 2 (ACT+) Battery negative (-) → 1 (ACT-) | Unlock |
(4) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
1 (ACT-) - 3 (D+) | Unlock | Below 1 Ω |
(b) w/ Power Back Door:
(1) Apply battery voltage to the door lock motor and check the operation of the door lock motor. OK: Tester Connection | Condition | Specified Condition | 1 (M+) - 4 (M-) | Battery positive (+) → 1 (M+) Battery negative (-) → 4 (M-) | Latch turns to full-latch position (clockwise rotation) | 1 (M+) - 4 (M-) | Battery positive (+) → 4 (M-) Battery negative (-) → 1 (M+) | Latch turns to open-latch position (counterclockwise rotation) | | | *a | Component without harness connected (Back Door Lock Assembly (Back Door Courtesy Switch)) | *b | Clockwise | *c | Counterclockwise | | |
(2) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | 8 (CTY) - 7 (E) | Open-latch | Below 1 Ω | 8 (CTY) - 7 (E) | Half-latch | Below 1 Ω | 8 (CTY) - 7 (E) | Half-latch → Full-latch | Below 1 Ω → 10 kΩ or higher | 8 (CTY) - 7 (E) | Full-latch | 10 kΩ or higher | 8 (CTY) - 7 (E) | Over-latch | 10 kΩ or higher | If the result is not as specified, replace the back door lock assembly (back door courtesy switch). | | *a | Component without harness connected (Back Door Lock Assembly (Back Door Courtesy Switch)) | *b | Open-latch | *c | Half-latch | *d | Full-latch | | |
