911 Carrera (996) Roll-over protection system diagnosis Test point 7 Solenoidvalve 1 This fault is stored in the memory in the event of a short to B+ in the Short to B+ supply lead of solenoidvalve 1 (triggers roll-over bar). Fault code 7 1. Pull off plugs on control module and on solenoid valves 1 and switch on the ignition. Measurevoltage between plug on control module pin 4 and ground Voltmeter display: 0 V Test point 8 Solenoidvalve 2 This fault is stored in the event of a short to ground in the lead of Short to ground solenoidvalve 2. Fault code 9 Pull off plug on control module and on solenoid valve 2. Measureresistance between plug on control module pin 17 and ground Ohmmeterdisplay: 00Q Push plug onto solenoidvalve 2 again. Unplug connector X10 from the subframe. Measureresistance between pins 3 and 4 Ohmmeterdisplay: 4 to 6 Q at 200 C Test point 9 Solenoidvalve 2 This fault is stored in the memory if there is an open circuit in the Open circuit supply lead to solenoid valve 2. Fault code 10 1. Pull off plug on control module and on solenoid valve 2 Measure resistance between plug on control module pin 17 and plug on solenoidvalve 2 pin 2 Ohmmeterdisplay: < 5 Q 2.
