Instrument cluster K20 911 Turbo (996)90 In these circumstances, no fault is present in the system and the fault memory must be erased. Fault memory Info key F8 In order to be able to assess the fault exactly, the fault memory Info key F8 must be pressed. This information should be saved using the Save key F4 and printed out. If a fault code is stored with "not present" status and no other problems are present, then the fault memory must be erased. Open circuit - short to ground / voltage short / version; vehicle parameters / counter Below short to ground limit There is (present) or was (not present) a short circuit to ground or an open cir- value: cuit in the circuit to the control module terminal. Voltage short: There is (present) or was (not present) a short circuit to voltage. Checking Renewed check of fault memory - information after the ignition is switched off and subsequently switched on again. If the fault memory has been remedied, the text changes from "present" to not "present" Total mileage Kilometer reading under which the fault has been saved Vehicle speed The value indicates the vehicle speed at the time the fault occurred. Version / Incorrect vehicle coding or coding not yet carried out. vehicle parameters: Counter: When a fault first occurs, a fault entry is made in the fault memory and the counter is simultaneously set to 50. If a fault is present, the counter is incre- mented by 1 each time the ignition is switched on. The maximum count is 100. The counter is decremented if the fault is no longer present. The fault memory is erased automatically when the counter reaches 0. Vehicle hand-over The instrument cluster is converted into delivery mode (low-current mode) in production. As known from other systems (alarm system, PCM, roll-over bar), the instrument cluster must be activated with the Porsche Sytem Tester 2. 1. Connect PST2 and switch on ignition. 2.
