I - PREPARATION OPERATION FOR CHECK
aRemove the plugs (see 17A, Ignition, Plugs: Re-
moval - Refitting, page 17A-12) .
aConnect a petrol compression gauge (1) .
aRun command with Diagnostic tool :
-RZ009: VEHICLE FUNCTION PROGRAMMING,
-VP036: FUEL SUPPLY INHIBITION.
aPut the vehicle under the starting conditions by posi-
tioning the gear lever in neutral.II - TEST OPERATION
aActivate the starter until the needle of the petrol
compression gauge stabilises.
aMeasure the cylinder compressions, cylinder by cyl-
inder.
aFully depress the accelerator pedal in order to open
the throttle valve during the compression measure-
ments.
III - FINAL OPERATION
aDisconnect the petrol compression gauge.
aRefit the plugs (see 17A, Ignition, Plugs: Removal
- Refitting, page 17A-12) .
aRun command VP037: "STOP INHIBIT FUEL SUP-
PLY" using the Diagnostic tool.
aStart the engine. Equipment required

Diagnostic tool
Note:
Use a petrol compression gauge compatible with
the special tools.
The petrol compression gauge must be equipped
with a universal end piece (rubber), or a gaz 1/4

Note:
It is necessar y to wait for at least 10 seconds
before starting the engine each time (the starter
