Scan Tool Testing and Procedures

Control 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 resistors from being measured with the ohmmeter from the outside.

CAN comfort
Communication between the Porsche System Tester II 9588 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)
The CDC is available as an optional feature and is linked to the PCM2 via the optical waveguide.
