Dirt entry into the systemmust be totally prevented
as CR system uses extremely close tolerance parts
Checking faults:
l
Connect diagnostic tool to diagnostic socket of
wiring harness(16 pin)
l
Select the correct application
l
Every fault has unique Fault code
l
Diagnostic tool gives fault codewith faultdescription
