Solenoid Control System, Replacing

Solenoid control system, replacing

Note: As the illustrations in this service information are used for different model years and/or models, some variation may occur. However, the essential information is always correct.

Preparatory work
Removing the control system cover
Remove the control system cover. See: Cover control system, replacing

Removal
Disconnecting the solenoid connector

Caution: Do not damage the wiring and connectors.





Disconnect the connectors from the solenoids.

Diagnostic testing of the solenoids, SLS SILT and SLU





Note: Readings should be taken at approximately 20°C.

Solenoid SLS SLT and SLU





Measure the resistance between both the pins in the solenoid connector. Correct value: 5.0-5.6 0.

If the value of any of solenoids SLS SLT and SLU is incorrect
Replace the control system. The control system is calibrated together with the solenoids.

Diagnostic testing of solenoid S1-S5

Note: Readings should be taken at approximately 20°C.





Solenoid S1
Measure the resistance between the pin in the solenoid connector and the transmission ground terminal.
Correct value: 12 - 16 ohms.

Solenoids S2-S5
Measure the resistance between the pin in the solenoid connector and the transmission ground terminal.
Correct value: 11 - 15 ohms.

If the resistance of any of solenoids S1-S5 is incorrect
Replace the solenoid. See: Replacing solenoid S1-S5. Replacing solenoid S1-S5 Remove the screw from the solenoid. Remove the solenoid from the control system.
Lubricate the O-ring on the new solenoid. Use automatic transmission fluid.





Install the solenoid. Tighten the screw. See: Specifications

Installation
Installing the solenoid connector

Caution: Do not damage the wiring and connectors.





Connect the connectors to the solenoids.

Finishing
Installing the control system cover
Install the control system cover. See: Cover control system, replacing.
