• Ground return circuit is failed 7 times continuously after the low & reverse brake duty solenoid output signal turn on. • All solenoid operations are stopped (OFF), the gear is fixed to the 3rd, and the lock-up is inhibited. (In case of fail-safe valve failure, gear shift to 4th (over-drive) and lock-up are inhibited.) • Ground return wire open circuit between terminal assembly terminal 11 and TCM terminal B22 (C95). • Poor connection of each connector.
