Was bedeutet der Fehlercode?
The fault concerns an open circuit in the circuit to linear pressure solenoid SLB1, even though it is named too low signal. The solenoid then cannot regulate the system pressure, which affects the lock-up function and gear changes.
Mögliche Ursachen
- Contact resistance in the connectors
- Open circuit in the control signal or signal ground wire
- Linear pressure solenoid SLB1 does not function
- The TCM is not working
Was Sie tun können
- 1Clear the fault code and road test; if it returns, the break is probably still present
- 2If you have a diagnostic tool: read the SLB1 solenoid value in live data during a road test and see whether it changes
- 3Check that the wiring and connectors from the gearbox are secure and not corroded
- 4Use a multimeter to check that the wire to the SLB1 solenoid is intact along its whole length
- 5If the wire is intact, have a workshop decide whether the solenoid or the control module needs replacing
Symptome, die Sie bemerken können4
- The general warning lamp is lit
- The malfunction indicator lamp is lit
- The lock-up function does not work
- Harsh gear changes
Was der Fehler beeinflussen kann1
- An auxiliary program in the control module is activated
