  2. Disconnect motor connector from steering gear case assembly with ignition switch turned OFF.
  3. Check for resistance between terminals of motor connector.

    If check result is not as specified, replace steering gear case assembly.

    Motor circuit resistance 

    MOTOR CIRCUIT RESISTANCE SPECIFICATIONS

    "E12-1" and "E12-2" (For motor) Approx. 1 Ω
  4. Check for no continuity between each terminal of motor connector and body ground.

    If check result is not as specified, replace steering gear case assembly.
