CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM - Transmission Control Switch Circuit |
DESCRIPTION
After moving the shift lever to M, it is possible to switch the shift range between "1" (M1 range) and "7" (M7 range) using the transmission control switch.Moving the shift lever to "+" once raises the shift range by one, and moving the shift lever to "-" lowers the shift range by one.

INSPECTION PROCEDURE
1.INSPECT TRANSMISSION CONTROL SWITCH |
Disconnect the transmission control switch connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Condition
| Specified Condition
|
3 (IG) - 7 (S)
| Shift lever in M, "+" or "-"
| Below 1 Ω
|
2 (SFTU) - 5 (E)
| Shift lever held in "+" (Up-shift)
| Below 1 Ω
|
1 (SFTD) - 5 (E)
| Shift lever held in "-" (Down-shift)
| Below 1 Ω
|
3 (IG) - 7 (S)
| Shift lever not in M, "+" or "-"
| 10 kΩ or higher
|
2 (SFTU) - 5 (E)
| Shift lever in M
| 10 kΩ or higher
|
1 (SFTD) - 5 (E)
| Shift lever in M
| 10 kΩ or higher
|

| REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
Replace the ECM (RAV4_ACA30 RM0000017UO01KX.html).
- NOTICE:
- Performing reset memory will clear the learned values of both the yaw rate sensor assembly*1 or deceleration sensor*2 (deceleration sensor 0 point calibration) and CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate sensor assembly*1 or deceleration sensor*2 0 point calibration and CVT oil pressure calibration when replacing any of the parts shown in the following table:
Replaced Part
|
- Continuously variable transaxle assembly
- ECM
- Oil pressure sensor
- Yaw rate sensor assembly (w/ VSC)
- Deceleration sensor (w/o VSC)
- Brake actuator assembly (skid control ECU)
|
- After performing reset memory, always perform yaw rate sensor assembly*1 or deceleration sensor*2 (deceleration sensor 0 point) calibration first, and then CVT oil pressure calibration.
- Always perform 0 point calibration with the vehicle on level ground.
- Do not shake or vibrate the vehicle during 0 point calibration.
Using the intelligent tester, perform reset memory, deceleration sensor 0 point calibration and CVT oil pressure calibration (RAV4_ACA30 RM000003UQR002X.html).
Check that no DTC is stored.
