Diagnostic Test
- PERFORM COMPONENT FUNCTION CHECK-I
Without CONSULT
- Start engine and warm it up to the normal operating temperature.
- Turn ignition switch OFF and wait at least 10 seconds.
- Restart engine and keep the engine speed between 3, 500 and 4, 000 RPM for at least 1 minute under no load.
- Let engine idle for 1 minute.
- Check the voltage between ECM harness connector terminals under the following condition.
ECM Condition Voltage Connector + - Terminal Terminal F11 50
(HO2S2)59 Revving up to 3, 600 RPM under no load at least 10 times The voltage should be above 0.75 V at least once during this procedure.
Is the inspection result normal?
YES
INSPECTION END
NO
GO TO STEP 2 .
- PERFORM COMPONENT FUNCTION CHECK-II
Check the voltage between ECM harness connector terminals under the following condition.
ECM Condition Voltage Connector + - Terminal Terminal F11 50
(HO2S2)59 Keeping engine at idle for 10 minutes The voltage should be above 0.75 V at least once during this procedure. Is the inspection result normal?
YES
INSPECTION END
NO
GO TO STEP 3 .
- PERFORM COMPONENT FUNCTION CHECK-III
Check the voltage between ECM harness connector terminals under the following condition.
ECM Condition Voltage Connector + - Terminal Terminal F11 50
(HO2S2)59 Coasting from 80 km/h (50 MPH) in D position (CVT), 4th gear position (M/T) The voltage should be above 0.75 V at least once during this procedure. Is the inspection result normal?
YES
INSPECTION END
NO
