I don't think reverse camera was ever an option on the 997 PCM3.0. On the Cayenne with PCM3.0 the camera outputs were connected to the TV tuner, and the TV tuner to the PCM. My guess is that you would have to code the PCM to add the TV tuner feature. Trouble is that this requires an Activation Code, which needs entering with a PIWIS tester. Not only that, but you would have to work out how to tell the PCM to switch to the TV input when the camera is required. There is a connection shown on the wiring diagram for the PCM labelled 'Back Cam' (with nothing connected to it), so that could be it. However, I suspect it is much more complicated than that.
Richard Hamilton replied to Eștii's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)The option 580 2002 Bose amp is an oddity. It amplifies the speaker outputs from the head unit. The 490 option Harman (Haes) amp uses the line outputs from the head unit. Drop me a PM with your email address if you would like the wiring diagrams.
Richard Hamilton replied to Eștii's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Are you sure you have an amp? Option code 490. The reason I ask is that you have speaker wires - the brown plug. The black plug has the power connections. The blue-green-yellow plugs go into the orange Metra socket, but only if you have the 490 amp. It looks to me like the wires to the green plug might be for a CD Changer.
The menus are different, and you won't get some features of the dot matrix cluster shown in your 2003 owners manual. You will get: Range on remaining fuel Outside air temperature (check the sensor is fitted) Speed gong Average speed Average fuel consumption Still worth having, for the minimal extra cost and effort.
Yes, your current instrument cluster will give you OBC if re-coded. You will still have the 7-segment OBC display, not the "dot matrix" display of models with factory OBC, but you will get the OBC functions. They will appear below the existing two lines. 7-segment: Dot Matrix
The fans have a separate control unit, which feeds off the front control unit. Get a diagnostic check done, and it will probably tell you what is wrong. They are prone to stones jamming the fan blades, so it might be worth checking that first. Edit - just saw someone else suggested checking for stones in another thread which you replied to.
Just to eliminate the passenger door window regulator, lower the window 2 or 3 inches from the top. Grab the window, and try to move it up and down. If it moves 1/2 inch or so, the regulator cables have slack in them, hence why it doesn't drop properly. A double honk means there is a fault in the alarm system. Use the Durametric to clear the codes, then lock and unlock it, and read any fault codes which come back.
Yes, I think you would be best to get a diagnostic scan with a Porsche tester. Any good independent will have the equipment.
I guess the problem could be with the microswitch which senses the key being turned to the lock position. I believe the convertible top will go up and the car will lock if the key is held in this position. It is odd that it happens randomly, and that the central locking button on the dash also won't work sometimes. I would have thought that a problem with the alarm control unit would more likely cause faults like that. Any dampness under the left hand seat (driver's side in the US)? That's where the alarm unit is located.
It sounds like a microswitch within one of the door locks which senses if the door is open or closed is broken. The system 'thinks' the door is open, so after locking it immediately unlocks. As a temporary measure, you can use the emergency locking procedure. Turn the key in the door lock to the lock position and back 3 times in quick succession. It may also work if you press the remote button 3 times.
Try looking in the input signals of the alarm control module on PIWIS. These are from PIWIS2 in Simulation Mode. Select Alarm from the Overview screen, then Maintenance repairs, and choose Input Signals.
It is anyone's guess, I'm afraid. They used to release updates every two years or so, but these systems are up to 14 years old, so I guess they will stop supporting it at some point. The updates are seldom up to date anyway. If you put your DVD in a PC and check out the database file dates, they will likely be older than 2013.
The latest USA map for PCM2.1 is indeed 997.044.904.51, which is mid-2015. Because you are running the 2013 map, your system must have been updated in the past, so the new map disk would be plug & play. PCM version 5024AD1 is software level B. You may also have read that there is a Level C update, which yours must have had. However, when you update from Level B to Level C, it only updates the Navigation Drive, not the PCM head unit. If you view the software version for Navigation, it should show Actual:00179436, which is Level C for the Navigation drive.
