Toyota Yaris: Front Door Lock / Inspection
INSPECTION
PROCEDURE
1. INSPECT FRONT DOOR WITH MOTOR LOCK ASSEMBLY RH
(a) Check the resistance of the lock and unlock switch. (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | K11-6(L) - K11-8(E) | Lock | Below 1 Ω | K11-6(L) - K11-8(E) | Neutral | 10 kΩ or higher | K11-5(UL) - K11-8(E) | Unlock | Below 1 Ω | K11-5(UL) - K11-8(E) | Neutral | 10 kΩ or higher | If the result is not as specified, replace the front door with motor lock assembly RH. |
| *a | Component without harness connected (front door with motor lock assembly RH) | *b | Unlock | *c | Neutral | *d | Lock | | |
(b) Check the door lock motor operation. (1) Apply auxiliary battery voltage to the motor connector and check the operation of the door lock motor. OK: Tester Connection | Specified Condition | K11-4(L) - Auxiliary battery positive (+) K11-1(UL) - Auxiliary battery negative (-) | Lock | K11-1(UL) - Auxiliary battery positive (+) K11-4(L) - Auxiliary battery negative (-) | Unlock | If the result is not as specified, replace the front door with motor lock assembly RH. |
| *a | Component without harness connected (front door with motor lock assembly RH) | *b | Lock | *c | Unlock | | |
(c) Check the operation of the door unlock detection switch. (w/ Smart Entry and Start System)
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
K11-7(LSSR) - K11-8(E) | Lock | 10 kΩ or higher |
K11-7(LSSR) - K11-8(E) | Unlock | Below 1 Ω |
If the result is not as specified, replace the front door with motor lock assembly RH.
2. INSPECT FRONT DOOR WITH MOTOR LOCK ASSEMBLY LH
(a) Check the resistance of the lock and unlock switch. (1) Measure the resistance according to the value(s) in the table below. Standard Resistance: Tester Connection | Condition | Specified Condition | L11-9(L) - L11-7(E) | Lock | Below 1 Ω | L11-9(L) - L11-7(E) | Neutral | 10 kΩ or higher | L11-10(UL) - L11-7(E) | Unlock | Below 1 Ω | L11-10(UL) - L11-7(E) | Neutral | 10 kΩ or higher | If the result is not as specified, replace the front door with motor lock assembly LH. |
| *a | Component without harness connected (front door with motor lock assembly LH) | *b | Unlock | *c | Neutral | *d | Lock | | |
(b) Check the door lock motor operation. (1) Apply auxiliary battery voltage to the motor connector and check the operation of the door lock motor. OK: Tester Connection | Specified Condition | L11-4(L) - Auxiliary battery positive (+) L11-1(UL) - Auxiliary battery negative (-) | Lock | L11-1(UL) - Auxiliary battery positive (+) L11-4(L) - Auxiliary battery negative (-) | Unlock | If the result is not as specified, replace the front door with motor lock assembly LH. |
| *a | Component without harness connected (front door with motor lock assembly LH) | *b | Lock | *c | Unlock | | |
(c) Check the operation of the door unlock detection switch. (w/ Smart Entry and Start System)
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
L11-7(E) - L11-8(LSSR) | Lock | 10 kΩ or higher |
L11-7(E) - L11-8(LSSR) | Unlock | Below 1 Ω |
If the result is not as specified, replace the front door with motor lock assembly LH.
