The hydraulic pump is working and charged.
However, the electric lock is not engaging and I am stuck as to what to do at this point.
I have researched the forum to find any similar problems but I am unable to find anything.
I have tried to manually raise and lower the top to manually reset the system to no avail.
The car is garage kept so I have no water issues
Can anybody out there suggests a solution or direct me to any posts in the forum that can direct me to a solution?
Thanks for any responses.
This is the sequence with the top up and you want to put it down:
1) Turn D handle, the latch retainer switch opens, signalling the PTCM (Power Top Control Module) that you have unlatched the top.
The PTCM notifies the BCM (Body Control Module) over CAN BUS B to lower windows. The BCM responds with an "OK" on the windows and starts to stream the speed of the vehicle continuously to the PTCM.
From your post, we know that the PTCM and BCM are alive and talking to one another.
2) You press the button. The PTCM activates the electric trunk lock and simultaneously asks the CPL/SSM (Central Locking Pump/Security System Module) if the trunk is showing latched.
Once the electric trunk lock shows closed AND the CLP/SSM signals that the trunk is latched, the PTCM checks to for confirmation that the Top Open switch over the passenger's head and the divider switch are both closed, indicating that the divider is up and the top is open and pulled away from the windshield frame.
If the above is true, and if a valid speed indication is being presented, the PTCM starts the pump and the hydraulic sequence begins for top lowering.
ANY of these will stop things from happening:
If the CLP/SSM is out of order/dead/wet, it will not respond properly, the top will not move and the beeper sounds.
If the speed of the vehicle is over 9mph, the top will not move (or will stop moving) and the beeper sounds.
If there is no indication of vehicle speed, the top will not move and the beeper sounds.
If the CLP/SSM does not see that the trunk is fully closed, the top will not move and beeper sounds.
