  Note

  • Before performing the following inspection, make sure to follow the procedure as indicated in the troubleshooting flowchart. (See Troubleshooting Procedure.)

## Continuity Inspection

1. Inspect the following items:

  • Power steering fluid amount (See POWER STEERING FLUID INSPECTION.)
  • Power steering-related inspection (See STEERING LOCATION INDEX.)

2. Disconnect the PSP switch connector.

3. Start the engine.

4. Verify that the continuity between PSP switch terminal A and body GND is as indicated in the table.

  • If not as indicated in the table, replace the CPP switch. (See POWER STEERING OIL PUMP (ZJ, Z6) 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".

## Circuit Open/Short Inspection

1. Remove the PCM connector cover.

2. Disconnect the PCM connector. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [ZJ, Z6].)

3. Inspect the following wiring harness for open or short circuit (continuity check).

### Open circuit

  • If there is no continuity, there is an open circuit. Repair or replace the wiring harness.
