System Protection Functions

Normal operation of the folding top system may be altered by one of the following events.

Obstacle Detection

The obstacle detection implemented for the power convertible top is to protect the folding top mechanism and/or to detect a catastrophic mechanical failure.

The K23 Folding Top Control Module uses an algorithm to determine a mechanical failure based off of the time it takes to move the top in the open or close direction. The K23 Folding Top Control Module will turn off the M23 Folding Top Pump Motor to prevent overheating or damage to the mechanical structure of the top.

Folding Top System Thermal Protection

The K23 Folding Top Control Module has a thermal protection algorithm to protect the M23 Folding Top Pump Motor from damage due to overheating conditions resulting from excessive motor actuation. After the thermal protection has been triggered any new power convertible top command in the open direction will be ignored until the motor is allowed to cool. A close request during an over temperature condition will be allowed.
