INSPECTION PROCEDURE
PROCEDURE
1. CHECK LIGHTS
(a) Check the condition A or B, when room light assembly No. 1 does not light up.
Result:
B -- CHECK DRIVER SIDE JUNCTION BLOCK
A -- Continue to next step.
2. CHECK DOOR LOCK
(a) Check which door light does not light up.
Result:
D -- CHECK WITH MOTOR BACK DOOR LOCK ASSEMBLY
C -- CHECK REAR DOOR LOCK
B -- CHECK FRONT DOOR WITH MOTOR LOCK ASSEMBLY RH
A -- Continue to next step.
3. CHECK FRONT DOOR WITH MOTOR LOCK ASSEMBLY LH
(a) Check the continuity between terminal 8 (LSSR) of front door with motor lock assembly LH and body ground.
Standard:
NG -- REPLACE FRONT DOOR WITH MOTOR LOCK ASSEMBLY LH
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (BETWEEN BODY ECU AND FRONT DOOR WITH MOTOR LOCK ASSEMBLY)
(a) Check the continuity between terminal 8 (LSSR) of the front door with motor door lock assembly LH and B4-21 (LSWD) of the multiplex network body ECU.
Standard:
There is continuity
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE MULTIPLEX NETWORK BODY ECU
5. CHECK FRONT DOOR WITH MOTOR LOCK ASSEMBLY RH
(a) Check the continuity between terminal 7 (LSSR) of the front door with motor lock assembly RH and body ground.
Standard:
NG -- REPLACE FRONT DOOR WITH MOTOR LOCK ASSEMBLY RH
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (BETWEEN BODY ECU AND FRONT DOOR WITH MOTOR LOCK ASSEMBLY)
(a) Check the continuity between terminal 7 (LSSR) of the front door with motor door lock assembly RH and B4-30 (LSWP) of the multiplex network body ECU.
Standard:
There is continuity
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE MULTIPLEX NETWORK BODY ECU
7. CHECK REAR DOOR LOCK
(a) Check which door light does not light up.
(b) Measure voltage between terminals when unlocking the door.
Standard:
NG -- REPLACE REAR DOOR LOCK
OK -- Continue to next step.
8. CHECK HARNESS AND CONNECTOR (BETWEEN DRIVER SIDE JUNCTION BLOCK AND REAR DOOR LOCK)
(a) Check the continuity between terminals as shown in the chart below.
Standard:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE DRIVER SIDE JUNCTION BLOCK
9. CHECK WITH MOTOR BACK DOOR LOCK ASSEMBLY
(a) Measure voltage between terminal 4 (LS3) of with motor back door lock assembly and body ground.
Standard:
NG -- REPLACE WITH MOTOR BACK DOOR LOCK ASSEMBLY
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR
10. CHECK DRIVER SIDE JUNCTION BLOCK
(a) Measure voltage between terminal 1D-5 (ACC) of the driver side junction block and body ground.
Standard voltage:
OK -- CHECK DRIVER SIDE JUNCTION BLOCK (ILE)
NG -- Continue to next step.
11. CHECK HARNESS AND CONNECTOR (BETWEEN DRIVER SIDE JUNCTION BLOCK AND IGNITION SWITCH)
(a) Check the continuity between terminal 1D-5 (ACC) of the driver side junction block and the ignition switch assembly.
Standard:
There is continuity
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE IGNITION OR STARTER SWITCH ASSEMBLY
12. CHECK DRIVER SIDE JUNCTION BLOCK (ILE)
(a) Measure voltage between terminals as shown in the chart below when turning the ignition switch to OFF.
Standard voltage:
NG -- REPLACE DRIVER SIDE JUNCTION BLOCK
OK -- Continue to next step.
13. CHECK HARNESS AND CONNECTOR (BETWEEN DRIVER SIDE JUNCTION BLOCK AND LIGHT)
(a) Disconnect the connector of the driver side junction block.
(b) Check the continuity between terminals as shown in the chart below.
Standard:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
14. CHECK TRANSPONDER KEY AMPLIFIER (IGNITION KEY CYLINDER LIGHT)
(a) Check the continuity between terminals of transponder key amplifier (ignition key cylinder light).
Standard:
There is continuity.
NG -- REPLACE TRANSPONDER KEY AMPLIFIER
OK -- Continue to next step.
15. CHECK ROOM LIGHT ASSEMBLY NO.1
(a) Check the continuity between terminals of the room light assembly No. 1.
Standard:
There is continuity.
NG -- REPLACE ROOM LIGHT ASSEMBLY NO.1
OK -- REPLACE ROOM LIGHT ASSEMBLY NO.2
