Corsa C
Compression 4-cylinder, Diesel
Objective: Determining the compression efficiency of the individual cylinder by measuring the difference in voltage between the compression and decompression process. Measurement: Recording of the battery voltage variations during the start procedure. Preparation: Switch off engine. Switch off ignition. Prepare engine not to start (e.g. remove the fuse to the engine control unit or remove engine main relay). Engine oil temperature 20-80°C . Note: For some engines it is possible to prevent the engine from starting by performing an actuator test with the Tech 2. Connections:
Procedure Tech 31:
Procedure Tech 32: This measurement is not possible using the Tech 32. The Tech 31 has a preprogrammed function to perform this measurement, which is not available in the Tech 32. |
