HighLine - supporting MFSW / CCS
MidLine - Supporting CCS
LowLine - not supporting MFSW and CCS (basic)
If your car use External BT module , you need to keep HighLine SWCM , and install Emulator , because only this configuration will allow you to operate BT from cluste.
For all others cars , with no BT, built-in BT into radio such as RNS 315, or MIB2 STD , you can use LowLine module, no need to keep HighLine , because you need to recode it to LOW anyway.
How to check if SWCM can be use as LowLine ?
5K0 953 5* SWCM
1) Disable MFSW from cofing and check if module accpet coding
1K0/3C0
and check if module accpet coding
2) Some modules even if accept LowLine coding
They still show in DTC errors - No communication with Steering Control Wheels
I they accepet coding to LowLine , and no error , please check if you can control Horn in this configuration
Simple connect PIN 7+8 and check if this activate horn
if HORN working = module can be use LowLine
if Horn not working, or working always even if you not connect 7+8 = module not support LowLine and must be use with emulator
you can find out proper Lowline module
