The front six-pack (6 solenoids) includes:
1) a pair of travel solenoids that should be activated (power to the coils when the system is in travel mode
2) a left and right exhaust solenoid that should NOT have power when in travel mode
3) a left and right raise solenoid that should NOT have power when in travel mode
That should be fairly easy to verify if for some reason in travel mode the raise solenoids are getting power and adding air to the bags. Even if they were, it would seem that once the travel height valve got too high, built in exhaust would open and start releasing the air at about the same quantity as the errant raise solenoid was adding it in. Temporarily disconnect the power leads to the raise solenoids and see that changes anything. If not, you are back to the front height control valve again.
