Connect the GDS to the Data Link Connector (DLC).
Measure the CVVL lift value in the IG ON and the idle condition.
Conditions | Lift value (mm) |
IG ON | 6 ~ 9 |
Idle (Engine warm up, 650 rpm) | 1 |
The Lift value moves to 9mm lift when IG OFF.
If it is not reached to 9 mm by mechanic friction, check if the lift value is normal in the engine warm up condition while repeating IG ON/OFF 3~4 times.
Check sensor / wheel interference, damage, foreign matter.
Check connector connection, wiring open/short, contamination.
