91-104Control module function - external BOSE amplifier · Terminating resistors on the CAN

911 Turbo (996) PCM2/CDR23 91 91-104Control module function - external BOSE amplifier 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 resis- tors from being measured with the ohmmeter from the outside. CAN comfort Communication between the 9588 Porsche System Tester ll and the MOST control modules only takes place via the K lead to the instrument cluster. The data is transferred from the instrument clus- ter 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) The CDC is available as an optional feature and is linked to the PCM2 via the optical waveguide.
