Was bedeutet der Fehlercode?
Hydraulic pressure on clutch 1 (odd gears) reads higher than requested. The transmission controls the pressure using a hydraulic pump and solenoids. The cause may be a damaged power stage, a damaged solenoid CSPS1 or CSMS1, a damaged valve CSM1, or a damaged pressure or temperature sensor.
Mögliche Ursachen
- Damaged output stage, solenoid CSPS1
- Damaged pressure sensor
- Damaged solenoid CSPS1
- Damaged solenoid CSMS1
- Damaged valve CSM1, which routes the pressure between clutch and gear shifting
- Damaged temperature sensor
Was Sie tun können
- 1Read the fault codes, clear TCM-05A4 and drive the car to see whether it comes back
- 2Have a workshop check that the wiring to solenoid CSPS1 has no open circuit and no contact with ground
- 3Have a workshop read the pressure and temperature sensors with diagnostic equipment
- 4Have a workshop open the transmission control system and check the solenoids, valve CSM1 and the oil level. Replace the mechatronic unit if the fault cannot be fixed
Symptome, die Sie bemerken können5
- Yellow warning symbol and text message in the display
- Shifts hard or jerky
- Gear changes take too long to complete
- Shifts too early, too late or too often
- No forward or reverse movement with a gear selected
