| 122-T7Y5Q-12 | 2017-12-14. Service bulletin. ELECTRICAL SYSTEM. Information: This document updates information previously published in EQ 1105, EQ 1105, and EQ 1401. To provide stable voltage and sufficient current throughout certain service operations, you should connect the vehicle to a battery charger (sometimes referred to as a power supply). However, you may experience ECU programming and coding issues if the chosen battery charger has insufficient power. Many workshop manuals currently advise use of a battery charger with a 40 or 70 A current rating. However, with the increasing current requirements of modern Porsche vehicles, we recommend a battery charger capable of producing a minimum current of 90 A. |

| 122-T5Z7V-08 | 2017-10-25. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Technical Concern: The technician confirms the MIL and notes P0C4700 is present in the high voltage battery. |
| 122-W6E3D-03 | 2017-10-25. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. No cooling in the passenger compartment. NOTE: A low state of charge of the High Voltage Battery can cause the AC to be deactivated until the state of charge increases to an adequate level. Customers who do not plug their vehicle in on a regular basis may have this issue. There are two shut off valves in the refrigeration circuit. 1. The chiller shut off valve is normally open and requires 12V be applied to it from the AC control unit to close it. This would stop cooling of the high voltage battery. a. Power and ground from the AC CU can be checked at the connector of the valve. 2. The evaporator shut off valve is normally closed and requires 12V to be applied to it, via a relay, in order for the valve to open and provide cooling to the passenger compartment. a. The evaporator shut off valve can be diagnosed easily by removing the relay and jumping the load contacts of the relay to see if power makes it to the valve. Power at the valve opens it and the evaporator gets cold with normal AC operation. b. The relay winding circuit can be tested for power and ground from the AC CU. |
