id0140a7803100

Note
•  Perform the following inspection only when directed.

Continuity Inspection

1.  Inspect the following if the power steering is inoperative (See POWER STEERING FLUID INSPECTION.):

•  Power steering fluid level
•  Power steering fluid leakage
•  Power steering fluid pressure

2.  Disconnect the PSP switch connector.

3.  Start the engine.

4.  Inspect for continuity between the PSP switch terminal and GND using an ohmmeter.

•  If not as specified, replace the PSP switch.
•  If the PSP switch is okay, but PSP PID value is out of specification, perform the “Circuit Open Inspection”.

1.  Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION[L3].)

2.  Inspect the following harness for open or short. (Continuity check)


Open circuit

•  If there is no continuity, the circuit is open. Repair or replace the harness.
―  PSP switch terminal and PCM terminal 2S
―  PSP switch terminal and body ground


Short circuit

•  If there is continuity, the circuit is shorted. Repair or replace the harness.
―  PSP switch terminal and body ground
