4 CHECK INPUT SIGNAL CIRCUIT
1. Turn ignition switch ªOFFº.
2. Disconnect ECM harness connector.
3. Check harness continuity between ECM terminal 39 and terminal 1. Refer to wiring diagram.
Continuity should exist.
4. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 6.
NG©GO TO 5.
5 DETECT MALFUNCTIONING PART
Check the following.
+Harness connectors M5, E101
Check the harness for open or short between ECM and power steering oil pressure switch.
©Repair open circuit or short to ground or short to power in harness or connectors.
6 CHECK GROUND CIRCUIT
1. Disconnect power steering oil pressure switch harness connector.
2. Check continuity between power steering oil pressure switch harness connector terminal 2 and ground.
Continuity should exist.
OK or NG
OK©
NG©Repair open circuit or short to power in harness or connectors.
7 CHECK POWER STEERING OIL PRESSURE SWITCH
1. Disconnect power steering oil pressure switch harness connector then start engine.
2. Check continuity between terminals 1 and ground. Refer to wiring diagram.
