HBA diagnosis 911 Carrera (996) · Fault code 5

HBA diagnosis 911 Carrera (996) Fault code 5 5 V supply for axle This fault is stored in the following cases: position sensors (angle sensors for HBA) 1. Short circuit to voltage/ground in the supply leads between the control module and angle sensors for HBA 2. Angle sensor for HBAis faulty 3. The controlmoduleis faulty Note: The 5V supplyvoltage for the sensors is ensured via terminal 14 on the HBAcontrol module. A fault in this supply lead affects both angle sensors. Elimination: -Switch off ignition Pull plug off the angle sensor for HBA,front Switch ignition on Readthe fault memory and observe whether fault code 5 reappears If fault code 5 does not reappear,the supply lead to the angle sensor for HBA, front, is faulty. Proceed as follows in this case: Measure voltage between terminal 5 of the sensor plug and ground Voltmeter display approx. 5 V Measurevoltage betweenterminal 5 and terminal 1 of the sensor plug Voltmeter display approx. 5 V 94 -D 18 94 92 Diagnosis/troubleshooting HBA
