Continuity Inspection

  1. Disconnect the PSP switch connector.
  2. Start the engine.
  3. Verify no continuity between the PSP switch terminals while rotating the steering wheel.
    • If there is continuity, verify that P/S oil pump is normal and replace the PSP switch. (see POWER STEERING OIL PUMP DISASSEMBLY/ASSEMBLY .)
    • If the monitor item condition/specification (reference) is not within the specification, even though there is no malfunction, perform the "Circuit Open/Short Inspection".
