MXM155
Service: Transmission > Error Code F6A
Problem
Code F6A is in reality FbA, letter b looks like 6.
Fault: transmission disengaged, problems at the coupling solenoid clutch B.
Solution
1. Change the solenoid B if resistance is not 8 Ω – 11 Ω.
2. Check the solenoid circuit B (C027/PINA) at CFPS (C331/PIN3L/A/S), (C027/PINB-C331/PIN7/TQ/N/B).
3. Check the wires from C027 (PIN A and B) to see if they are not in short circuit.
4. If everything is ok change the CFPS.
