DTC Confirmation Procedure
Perform "PROCEDURE FOR MALFUNCTION A" first. If 1st trip DTC cannot be confirmed, perform "PROCEDURE FOR MALFUNCTION B".
NOTE:
If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.
PROCEDURE FOR MALFUNCTION A
With CONSULT
(1) Turn ignition switch "ON".
(2) Select "DATA MONITOR" mode with CONSULT.
(3) Wait at least 5 seconds.
With GST
(1) Turn ignition switch "ON" and wait at least 5 seconds.
(2) Select MODE 7 with GST.
No Tools
(1) Turn ignition switch "ON" and wait at least 5 seconds.
(2) Turn ignition switch "OFF", wait at least 5 seconds and then turn "ON".
(3) Perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.
PROCEDURE FOR MALFUNCTION B
CAUTION: Always drive vehicle at a safe speed.
TESTING CONDITION:
This test may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a road test is expected to be easier, it is unnecessary to lift the vehicle.
With CONSULT
(1) Wait until engine coolant temperature is less than 90°C (194°F).
(a) Turn ignition switch "ON".
(b) Select "DATA MONITOR" mode with CONSULT.
(c) Check the engine coolant temperature.
(d) If the engine coolant temperature is not less than 90°C (194°F), turn ignition switch "OFF" and cool down engine.
- Perform the following steps before engine coolant temperature is above 90°C (194°F).
(2) Turn ignition switch "ON".
(3) Select "DATA MONITOR" mode with CONSULT.
(4) Start engine.
(5) Hold vehicle speed at 70 km/h (43 MPH) for 100 consecutive seconds.
With GST
(1) Wait until engine coolant temperature is less than 90°C (194°F).
(a) Turn ignition switch "ON".
(b) Select MODE 1 with GST.
(c) Check the engine coolant temperature.
(d) If the engine coolant temperature is not less than 90°C (194°F), turn ignition switch "OFF" and cool down engine.
- Perform the following steps before engine coolant temperature is above 90°C (194°F).
(2) Start engine.
(3) Hold vehicle speed at 70 km/h (43 MPH) for 100 consecutive seconds.
(4) Select MODE 7 with GST.
No Tools
(1) Wait until engine coolant temperature is less than 90°C (194°F).
(a) Turn ignition switch "ON".
(b) Check voltage between ECM terminal 59 (Engine coolant temperature sensor signal) and ground.
Voltage: More than 1.0 (V)
(c) If the voltage is not more than 1.0 (V), turn ignition switch "OFF" and cool down engine.
- Perform the following steps before the voltage is below 1.0 V.
(2) Start engine.
(3) Hold vehicle speed at 70 km/h (43 MPH) for 100 consecutive seconds.
(4) Turn ignition switch "OFF", wait at least 5 seconds and then turn "ON".
(5) Perform "Diagnostic Test Mode II (Self-diagnostic results)" with ECM.
