PCM2/CDR23 911 Turbo (996)91 • Never start engine without securely connected battery. • Never pull off or push on plug connections for the control modules or other electronic components when the ignition is switched on. General information on the fault memory Fault code setting conditions Fault codes can be set in several circumstances, e.g.: ♦battery disconnected ♦plug connections disconnected ♦power failure 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. Fault type - Frequency counter/Temperature/Voltage; Speed/Time of occurrence. Fault type The display shows which fault type has occurred: ♦No GPS info ♦Gyroscope faulty Frequency 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 for each "ignition on". The maximum count is 100. The counter is decremented if the fault is no longer present. The fault memory is erased auto- matically when the counter reaches 0. First occurrence (month, day): The date (month and day) on which the fault was first detected is displayed. . Temperature - first occurrence: The value indicates the temperature (temperature sensor in the gateway) at the time the fault occurred. The temperature of the fibre optic transmitter is moni- tored: max 85°C. Speed - first occurrence The value indicates the vehicle speed at the time the fault occurred. Supply voltage - first occurrence The value indicates the voltage at the time the fault occurred. Hourmeter - first occurrence The value indicates the operating hours at the time the fault first occurred. Last occurrence (month, day): The date (month and day) on which the fault was last detected is displayed. 91-130 page 2 9101 Navigation - introduction EINNAlwl Printed in Germany – 43, 2003
