Preliminary work: Diagnosis - Function Test 11

Prerequisite for reading DTC memory 1. Fuses O. K. 2. Battery voltage > 11 V. 3. Connect HHT according to connection diagram, see section 0. Erasing Retractable Hardtop (RH) DTC will also automatically erase Combination Control Module (CCM) DTC from memory. Note regarding DTCs Current diagnostic trouble codes are highlighted in black on the display. Additional detailed fault information based on fault type is displayed with nearly all diagnostic codes (DTC's) such as: > resistance too great < resistance too low + short circuit to positive (POS) - short circuit to ground (GND) -//- open circuit
