911 Carrera (996) Roll-over protection system diagnosis Test point 1 Warning light of roll-over This fault is stored in the memory if there is an open circuit or short to protection ground in the supply lead to the warning light in the instrumentcluster. Open circuit Open circuit Short to ground Fault code 1 1. Check bulb and replace if necessary. 2. Check wire to pin 12 for open circuit. Pull plug off the roll-over protection control module. Pull off plug III on the instrumentcluster. Measureresistance between plug on roll-over protection control module pin 12 and plug III on instrumentcluster pin 16 Ohmmeterdisplay: < 5 .Q Short to ground Measure resistance between plug on roll-over protection control module pin 12 and ground Ohmmeter display: 00.0. Test point 2 Warning light of roll-over This fault is stored in the memory if there is a short to B+ of the supply protection lead to the warning light in the instrumentcluster. Short to B+ 1. Pull off plug on control module and plug III on instrumentcluster. Fault code 2 Check wire to pin 12 for short to B+. Switch ignition on. Measurevoltage between plug on roll-over protection control module pin 12 and ground Voltmeter display: 0 V Test point 3 Supplyvoltage This fault is stored in the memory if the supply voltage is insufficient.
