body earth, and between earth
terminal 12 and body earth
- Code No.C1215 is set: Between signal terminal 2 and
body earth, and between earth
terminal 3 and body earth
Q.
Is the check result normal?
Go to Step
14.
NO (Continuity exists between terminal 5 or
terminal 6 and body earth) : Go to
Step 6.
