Description
Solenoid Assy Malfunction

Probable Cause
- Converter clutch solenoid failed
- Shift control solenoid failed.
- Pressure control solenoid failed
- Engine control module failed.

Background
- The transaxle control module monitors the torque converter clutch solenoid, shift control solenoid and pressure control solenoid.
- When some one of these solenoids has failed, the transaxle control module inputs these failure signals to the engine control module.

Range of Check
- Engine speed is 500 r/min or more.
- Position of selector lever: Except "P" or "N"

Set Conditions
The failure signals of the torque converter clutch solenoid, shift control solenoid or pressure control solenoid were input from the transaxle control module to the engine control module.

Diagnosis
Check the TCM.
