Various Electrical Problems Caused by Water Ingress. Water ingress into the luggage compartment may cause various electrical problems or faults associated with the MPM (Micro Power Module); PDC (Park Distance Control); M-ASK (Multi-Audio System Controller); CCC (Car Communication Computer); CID (Control Information Display); TCU (Telematics Control Unit); LOGIC-7 (Top Hi-Fi); RDC (Tire Pressure Monitor) or SDARS (Satellite Radio Receiver) control modules. In most cases, the water collects in the spare wheel recess. CAUSE: Insufficient sealing may allow water to enter the luggage compartment due to the vacuum generated while driving.
