Ignition Switch In Off Position

The system will operate for approximately 30 minutes after the ignition switch is turned from the RUN to the OFF position. Then, the system is inoperable through the microcomputer. The system will allow down requests only (lower vehicle) as required during the 30 minutes except that the exhaust control is suspended after continuous ON operation for one minute. Turning the ignition switch to ON position resets the operation. If the sensor arm moves to a neutral or low position, this function is also reset and normal ignition OFF venting control resumes.
