Test Stand Measurement

Inhalation of toxic exhaust gases
Danger of serious or fatal injuries due to inhalation of toxic exhaust gases.

Exhaust gas contains colorless and odorless carbon monoxide, which is toxic even in low concentrations.

  • Perform work with the engine running only outdoors or with suitable extraction systems for the exhaust gases.

Inadequate securing of vehicle
An unsecured or incorrectly secured vehicle can move unintentionally or tip or fall off lifting equipment such as a jack or lifting platform. This can cause serious injuries and damage.

  • Raise the vehicle using a jack on a solid and flat surface only.
  • Raise the vehicle at the prescribed jacking points (Fig. 86 on page 128, Fig. 87 on page 128) on the vehicle underbody only.
  • Always place the vehicle on solid supports when working under the vehicle.
  • Never start the engine when the vehicle is raised. Engine vibrations can cause the vehicle to fall.

Carrying out test stand measurements

Power measurement
Porsche does not authorize power measurements on roller-type test stands.

Carrying out brake tests

  • Brake tests must only be performed on roller-type test stands.

The following limits must not be exceeded:

  1. Test speed 4.6 mph (7.5 km/h)
  2. Test duration 20 seconds

In order to fulfill legal stipulations, measurements with different limit values are permissible (e. g. exhaust emissions tests etc.).

Carrying out electric parking brake tests

  • Electric parking brake tests on the brake test stand must only be performed with the ignition switched on and with the manual gearshift lever in neutral or with the selector lever in position N.

The vehicle switches automatically to the brake test stand mode in which the electric parking brake can be tested. A message appears on the multifunction display in the instrument panel.
