Terminating Resistors on the CAN
Terminating Resistors On The CAN
Terminating resistors are fitted to each end of the wiring to prevent reflection on the wiring. These terminating resistors are integrated into each control
module. The interconnection prevents the resistors from being measured with the ohmmeter from the outside.
Wake-Up Function
Wake-up Function
All MOST control modules connected to the CDR23 are in sleep mode if the CDR23 is deactivated. When the CDR23 is switched on, a 'light' is
switched on. It is reinforced and passed on by the MOST control modules that are connected.
CAN Comfort
CAN Comfort
Communication between the 9588 Porsche System Tester II and the MOST control modules only takes place via the K lead to the instrument cluster.
The data is transferred from the instrument cluster gateway to the MOST control modules, via CAN Comfort to the PCM2 gateway, via the electrical
MOST in the PCM2 and via the optical MOST outside of the PCM2.
CD Changer (CDC)
CD Changer (CDC)
The CDC is available as an optional feature and is linked to the PCM2 via the optical waveguide.
Data Transfer Fault
Data Transfer Fault
If faults are detected when the data is decoded, this is known as a data transfer fault. The faults can arise when the data is encoded, when the data is
transferred through an input level that is optically too low or when the data is decoded. A fault entry is not recorded.
External Amplifier
External Amplifier
The external amplifier (Harman or BOSE) is available as an optional feature and is linked to the PCM2 via the optical waveguide.
