With Manufacturer's Scan Tool
READ OUT OF DIAGNOSTIC TROUBLE CODECAUTION:
1. When battery voltage is low, no detection of failure is possible. Be sure to check the battery for voltage and other conditions before starting the test.
2. Diagnostic item is erased if the battery or the engine control module connector is disconnected. Do not disconnect the battery before the diagnostic result is completely read.
3. Be sure to connect or disconnect the scan tool with the ignition switch turned off. If the scan tool is disconnected with the ignition switch placed in the ON position, ABS diagnostic trouble code may be stored and ABS warning lamp turned on.
WHEN USING THE SCAN TOOL MUT-II
NOTE: Erasing DTC causes the "freeze frame" data also to be erased.
Put it down on paper if necessary.
At this time, the readiness test status is also reset.
1. Connect the scan tool to the data link connector.
2. Turn the ignition switch to ON.
3. Take a reading of the diagnostic output.
4. Repair the problem location, referring to the diagnostic chart.
5. After turning the ignition switch once to OFF, turn it back to ON.
6. Erase the diagnostic trouble code.
7. Read the diagnostic trouble codes. Check that the scan tool displays "normal".
DIAGNOSIS BY DIAGNOSTIC TEST MODE II (INCREASED SENSITIVITY)
When mode II is selected with MUT-II, the Check Engine/Malfunction Indicator Lamp will light when the ECM first detects the trouble. (Note that this is only for engine related trouble.) At the same time, the relevant diagnostic trouble codes will be registered.
In respect to the comprehensive component electrical faults (open/shorts), the time for the DTC to be registered after the fault occurrence is shortened (4 sec. 1 sec.)
With this, the confirmation of the trouble symptom and the confirmation after completing repairs can be reduced.
However, to return to the normal mode I after mode II has been selected once, the ignition switch must be turned OFF once or mode I must be reselected with the MUT-II. The DTC, readiness test status and freeze frame data, etc., will be erased when mode I is returned to, so record these if necessary.
1. Using the scan tool, changeover the diagnostic test mode of the engine control module to DIAGNOSTIC TEST MODE II. (INCREASED SENSITIVITY)
2. Road test the vehicle.
3. Read the diagnostic trouble code in the same manner as "READ OUT OF DIAGNOSTIC TROUBLE CODE" and repair the malfunctioning part.
4. Turn off the ignition switch will cause the engine control module to changeover the ECM from the diagnostic test mode II to the diagnostic test mode I.
NOTE: Turning OFF the ignition switch will cause the engine control module to change over the ECM from the diagnostic test mode II to diagnostic test mode I.
