terminal No.18 and body earth

OK: 1 k

Ω or more

CAUTION

Strictly observe the specified wiring harness
repair procedure. For details refer to

P.54D-8

.

Q: Is the check result normal?

YES :

<1 k

Ω or more> Follow diagnostic item 18,

Diagnose CAN bus lines thoroughly. Refer
to

P.54D-476

.
