2 Service Technical Information 66/19 2791 Symptom in Vehicle Interior - Red or Yellow Hybrid Warning Message Appears in the Instrument Cluster: Re-programming control unit for high-voltage power electronics (SY 66/19) ENU Vehicle Type: 918 Spyder Model Year: As of 2012 up to 2018 Subject: High-voltage power electronics on front axle/High-voltage power electronics on rear axle Symptom: • • The red warning message "Hybrid system failure" or the yellow warning message "Hybrid system fault" appears in the instrument cluster. Hybrid system warning messages The vehicle no longer starts the engine from Start Stop mode; it can only start driving after the ignition has been switched off and on again. Hybrid system warning messages Cause: • • Due to a software error in the high-voltage power electronics, a fault memory entry (P0A1B00 High-voltage power electronics – function restriction) can be set at times in the control units for high-voltage power electronics on front axle or high-voltage power electronics on rear axle, resulting in the symptoms described here. The fault memory entry is deleted by switching the ignition off and on again. A highly discharged high-voltage battery increases the probability that the fault memory entry will be set. AfterSales Aug 29, 2019 Page 1 of 5 2 Service 2791 Remedial Action: ENU Technical Information 66/19 In the event of a customer complaint and if a software version lower than "F640" is installed in the control unit for high-voltage power electronics on the front axle or lower than "R640" is installed in the control unit for high-voltage power electronics on the rear axle, re-program the control units for high-voltage power electronics on front axle and high-voltage power electronics on rear axle. Information Tools: • The total time required for control unit programming is approx. 10 minutes. • • 9900 - PIWIS Tester 3 with installed PIWIS Tester test software version 38.600.000 (or higher) Battery charger with a current rating of at least 90 A. Preparatory work NOTICE Caution! Battery will be permanently damaged if unapproved battery charging equipment is connected. Battery charger voltage must NOT exceed 13.8 Volts or battery damage will result! NOTICE Fault entry in the fault memory and control unit programming aborted due to low-voltage. • Increased current draw during diagnosis or control unit programming can cause a drop in voltage, which can result in one or more fault entries and the abnormal termination of the programming process. Before commencing work, connect a suitable battery charger with a charging current of at least 90 A to the jump-start terminals in the front storage compartment. NOTICE Control unit programming will be aborted if the WLAN connection is unstable. • An unstable WiFi connection can interrupt communication between the PIWIS Tester and the vehicle communication module (VCI). As a result, control unit programming may be aborted. During control unit programming, always connect the PIWIS Tester to the vehicle communication module (VCI) via the USB cable. NOTICE Control unit programming will be aborted if the driver's key is not recognized • If the driver's key is not recognized in vehicles with Porsche Entry & Drive, programming cannot be started or will be interrupted. Switch on the ignition using the original driver’s key. To do this, replace the control unit in the ignition lock with the original driver’s key if necessary.
