Seat Slide Operation |
OK:
Motor operates normally.
NG | ![]() | GO TO STEP 7 |
|
4. | CHECK POSITION CONTROL ECU AND SWITCH ASSEMBLY LH (SLIDE MOTOR CIRCUIT) |
(a) Disconnect the c1 slide motor (front seat adjuster assembly LH) connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
c1-2 (O/P) - c1-3 (GND) | Slide switch on | 4.8 to 5.1 V |
NG | ![]() | GO TO STEP 6 |
|
5. | CHECK SLIDE MOTOR (FRONT SEAT ADJUSTER ASSEMBLY LH) |
(a) Reconnect the c1 slide motor (front seat adjuster assembly LH) connector. |
|
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
c1-2 (O/P) - Body ground | Slide motor operating | 4.5 to 4.8 V |
OK | ![]() | REPLACE POSITION CONTROL ECU AND SWITCH ASSEMBLY LH |
NG | ![]() | REPLACE SLIDE MOTOR (FRONT SEAT ADJUSTER ASSEMBLY LH) |
6. | CHECK HARNESS AND CONNECTOR (POSITION CONTROL ECU AND SWITCH ASSEMBLY LH - SLIDE MOTOR (FRONT SEAT ADJUSTER ASSEMBLY LH)) |
(a) Disconnect the c6 position control ECU and switch assembly LH connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
c6-5 (SSRS) - c1-2 (O/P) | Always | Below 1 Ω |
c6-5 (SSRS) or c1-2 (O/P) - Body ground | Always | 10 kΩ or higher |
c6-1 (SGND) - c1-3 (GND) | Always | Below 1 Ω |
c6-1 (SGND) or c1-3 (GND) - Body ground | Always | 10 kΩ or higher |
OK | ![]() | REPLACE POSITION CONTROL ECU AND SWITCH ASSEMBLY LH |
NG | ![]() | REPAIR OR REPLACE HARNESS OR CONNECTOR |
7. | INSPECT SLIDE MOTOR (FRONT SEAT ADJUSTER ASSEMBLY LH) |
(a) Remove the front seat adjuster assembly LH.
Click here
(b) Inspect the front seat adjuster assembly LH (slide motor).
Click here
NG | ![]() | REPLACE SLIDE MOTOR (FRONT SEAT ADJUSTER ASSEMBLY LH) |
|
8. | CHECK HARNESS AND CONNECTOR (POSITION CONTROL ECU AND SWITCH ASSEMBLY LH - SLIDE MOTOR (FRONT SEAT ADJUSTER ASSEMBLY LH)) |
(a) Disconnect the c5 position control ECU and switch assembly LH connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
c5-3 (SLD+) - c1-4 (FWD) | Always | Below 1 Ω |
c5-3 (SLD+) or c1-4 (FWD) - Body ground | Always | 10 kΩ or higher |
c5-4 (SLD-) - c1-1 (BACK) | Always | Below 1 Ω |
c5-4 (SLD-) or c1-1 (BACK) - Body ground | Always | 10 kΩ or higher |
OK | ![]() | REPLACE POSITION CONTROL ECU AND SWITCH ASSEMBLY LH |
NG | ![]() | REPAIR OR REPLACE HARNESS OR CONNECTOR |
