Q: Is the check result normal?

YES :

<All the resistances measure 2

Ω or less>

Power supply to the ABS-ECU <vehicles
with ABS> or ASTC-ECU <vehicles with
ASTC> may be suspected. Diagnose the
ABS or ASTC. Refer to <vehicles with
ABS> or <vehicles with ASTC>.

NO :

<Either or all of the resistances measure
more than 2

Ω> Repair the wiring harness

between intermediate connector (C-13) and
the ABS-ECU <vehicles with ABS> or
ASTC-ECU <vehicles with ASTC>
connector.
