VAS 5051 should immediately indicate "System OK"
- Repeat test several times to verify result.
If test continues to indicate "System OK", remove clamp and proceed to "Test EVAP System".
If VAS 5051 indicates "System not OK":
- Replace LDP and repeat test.
If VAS 5051 indicates "System OK" after LDP is replaced and test result is verified:
