Information On Pilot Line Fault Finding
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2023 Porsche Panamera, 2022 Porsche Panamera, 2021 Porsche Panamera, 2020 Porsche Panamera, and 2019 Porsche Panamera. However, it is still accessible from the selected car via links, so may be relevant.
Information
- The pilot line fault is identified by measuring the resistance.
- You need to use > V.A.G 1526E - Handheld multimeter , > VAS 6558/9-7 - High-voltage test adapter HVR 40 and > 9684 - measurement tool set to measure the resistance.
- Make sure not to damage the pins on the connectors when taking measurements.
- Refer to the wiring diagram for the pin assignment of the connectors.
- The measured values must be documented in the "Pilot line fault finding test log".
- The test log is stored under 2X00IN in the Service Information.
- If a part was replaced or if a connector contact was repaired, the measurement must then be repeated.
