    • If there is continuity, verify that the power steering 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".
