3.CHECK HARNESS AND CONNECTOR (TS of DLC3 - POWER STEERING ECU ASSEMBLY)
  1. Turn the ignition switch off.

  1. Disconnect the power steering ECU connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    Condition
    Specified Condition
    D102-12 (TS) - D104-6 (TS)
    Always
    Below 1 Ω
    D102-12 (TS) - Body ground
    Always
    10 kΩ or higher
  1. Reconnect the power steering ECU connector.
