Diagnostic ProcedureEBS0035T
1.CHECK START SIGNAL OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch “ON”.
2. Check “START SIGNAL” in “DATA MONITOR” mode with CON-
SULT-II under the following conditions.
OK or NG
OK >>INSPECTION END
NG >> GO TO 2.
2.CHECK START SIGNAL INPUT SIGNAL CIRCUIT
1. Turn ignition switch “OFF”.
2. Disconnect ECM harness connector and ignition switch harness connector.
3. Check harness continuity between ECM terminal D27 and ignition switch terminal 6. Refer to Wiring Dia-
gram.
4. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3.DETECT MALFUNCTIONING PART
Check the following.
lHarness connectors M63, F30
l10A fuse
lFuse block (J/B) connectors M1, E102
lHarness for open or short between ECM and ignition switch
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK INTERMITTENT INCIDENT
Refer toEC-699, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT".
>>INSPECTION END

POWER STEERING OIL PRESSURE SWITCH
POWER STEERING OIL PRESSURE SWITCH
PFP:49761
Component DescriptionEBS003PS
The power steering oil pressure switch is attached to the power
steering high-pressure tube and detects a power steering load.
When a power steering load is detected, it signals the ECM. The
ECM adjusts the fuel injector pulse width to increase the idle speed
and adjust for the increased load.
CONSULT-II Reference Value in Data Monitor ModeEBS003PT
Specification data are reference values.
ECM Terminals and Reference ValueEBS003PZ
Specification data are reference values, and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Diagnostic Procedure
EBS003PV
1.CHECK OVERALL FUNCTION
With CONSULT-II
1. Start engine.
2. Check “PW/ST SIGNAL” in “DATA MONITOR” mode with CON-
SULT-II under the following conditions.
OK or NG
OK >>INSPECTION END
NG >> GO TO 2.
2.CHECK POWER STEERING OIL PRESSURE SWITCH GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch “OFF”.
2. Disconnect power steering oil pressure switch harness connec-
tor.
3. Check harness continuity between power steering oil pressure
switch terminal 2 and engine ground. Refer to Wiring Diagram.
4. Also check harness for short to power.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to power in harness or con-
nectors.
3.CHECK POWER STEERING OIL PRESSURE SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND
SHORT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal E12 and power steering oil pressure switch terminal 1.
Refer to Wiring Diagram.
3. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 4.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK POWER STEERING OIL PRESSURE SWITCH
Refer toEC-823, "
Component Inspection".
OK or NG
OK >> GO TO 5.
NG >> Replace power steering oil pressure switch.
