Server Lease Renewal/Software Licenses
Our yearly server lease, software licenses, as well as hardware operating costs, ARE due Dec 6th, 2021. Our current donations have fallen far short of the funds we need to renew. Please remember the RennTech.org community is Member supported so please consider a donation to help... THANK YOU!

You also need to code the steering column contol unit.
The full process is:
Complete Control Module Search Code DME Code Instrument Cluster > Vehicle Variants Code Steering Wheel Electronics Ignition Off > On Complete Control Module Search and clear fault codes
Richard Hamilton's post in Coding Auto Lock with PST2 was marked as the answer
As it says, you need to do a full control module search before you can change the version coding in the alarm module. In other words, from the Vehicle Selection screen, choose 996 and press F12 to search all the modules first - do not just tab across to the alarm module.
Richard Hamilton's post in Radio upgraded but no sound in '02 model w/Bose was marked as the answer
You need to connect both the A5 aerial amplifier and the C6 wake-up signal to the antenna output from the head unit. It doesn't need much current to the C6 connection, because the amp has separate supplies for the power connections.
Richard Hamilton's post in Help…I may have done something stupid! loss of PCM functions.(long was marked as the answer
The PCM message is typical of what happens when there is a break in the MOST loop. The 'System Error, Amplifier, CD Player, Nav System, Phone not available' messages are all from devices connected by this fibre-optic loop. Hence you can see the software versions of the devices in the head unit, but none of the external devices.
Just a thought. Can you eject the CD changer cartridge? I saw one last week where the internal fuse in the CDC had blown, and it had all the PCM error messages the same as yours.
Also, there is a possibility that the failed phone update has caused the PCM unit to lose its coding. I have seen this happen before too.
I don't think either of these would explain the PSM/PASM error messages though. As has been suggested, a diagnostic check is the starting point for troubleshooting problems like this.
Richard Hamilton's post in 2003 996 CDR-23 was marked as the answer
The security code stored in the CDR23 is matched with a code programmed in the DME. If the two codes match, the radio comes on.
The codes are not transmitted by the MOST bus. They are transmitted by the diagnosis line. This is a white/red wire connected to the green plug on the CDR.
Edit: There are companies who can remove the security codes, so that it can be used in any car. I know of 2 or 3 in the UK, but none in the US, I'm afraid.
