Model Line: Cayenne (92A)
Model Year: 2015
Equipment: Only headlights with LED bulbs
Concerns: Headlights, (central) headlight control unit and LED control unit
Information:
- In the event of spare parts requirements due to a hardware fault or
- when commissioning the headlight control unit/LED control unit using the PIWIS Tester
the following points must be observed:
The existing control units must not be replaced. -> The replacement of control units in the event of hardware faults is not a long-term solution. The fault codes that were entered previously are no longer present only in the new control unit (i.e. the fault codes are deleted). This does not correct the actual cause of the fault. The fault can occur again. |
-> If ‘Headlight start-up’ is cancelled “sporadically” by the Tester, control unit programming must also be carried out, see Step c). |
Preliminary work Carry out general preliminary work for control unit programming as described inWorkshop Manual ‘9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester – section on “Preliminary work”‘. Re-program headlight control unit: The basic procedure for programming a control unit is described in the Workshop Manual Workshop Manual ‘9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester – section on “Programming”‘. | |
| Required PIWIS Tester software version: | 15.200 (or higher) |
| Type of control unit programming: | Control unit programming using the
‘Campaign’ function in the Additional menu on the PIWIS Tester by entering a programming code. |
| Programming code: | J 7Q1Q |
| Programming sequence: | Read and follow the information and instructions on the PIWIS Tester during the guided programming sequence.
Do not interrupt programming. |
| Procedure in the event of error messages appearing during the programming sequence: | ->Workshop Manual ‘9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester – section on “Troubleshooting”‘. |
| Procedure in the event of abnormal termination of control unit programming: | Repeat control unit programming by entering the programming code again. |
| Subsequent work
Carry out general subsequent work for control unit programming as described in the Workshop ManualWorkshop Manual ‘9X00IN Basic instructions and procedure for control unit programming using the PIWIS Tester – section on “Subsequent work”‘. | |

For reprogramming and flashing Porsche
vehicles without a factory diagnostic device, Porsche recommends the following devices:
Recommended Pass Thru Devices:
J2534 Device

Pass Thru – Check ECU
Pass Thru – ECU Check verifies the vehicle compliance with the latest air polution restrictions of the following organisations:
– Environmental Protection Agency (EPA)
– California Air Resources Board (CARB).
Pass Thru – Check ECU checks the Vehicle Identification Number (VIN) stored in the vehicles Digital Motor Electronic (ECU) against the PAG database.
Pass Thru – Check ECU is free of charge and does not require any login.
How to perform a Pass Thru – ECU Check:
- Enter the Vehicle Identification Number (VIN).
- In case of EPA offical enter the CVN ID.
- In case of CARB offical enter the Cal ID.
- Click the “CHECK ECU Version” button.
If the VIN is valid you see:
VIN IS VALID – User has the latest Update
How to find the VIN:
The VIN is labeled inside the windscreen at the bottom right side: see sample.
How to get the CVN ID / Cal ID:
CVN / Cal IDs can be retrieved with a generic scan tool device.
