Place the shift lever in neutral position, press the brake pedal.
Press the engine start button to complete the engine start phase.

Force voltage «+» after the ignition switch immediately after the starter stops (so that the engine start is blocked, and compression can be measured in other engine cylinders).
Note. Wait at least 10 seconds before restarting the engine (starter activation is blocked by thermal protection).
Measure compression in other cylinders.
Disconnect the compression gauge.
Remove the card from the reader to interrupt the power supply «+» after the ignition is switched on and wait for a communication loss message to appear on the scan tool.
Note. If the message does not appear, please wait 9 minutes.
