METHOD OF READING AND ERASING DIAGNOSIS
CODES
Refer to GROUP 00 – How to Use Troubleshooting/Inspection
Service Points on the ’97 L200 Workshop Manual (Pub. No.
PWTE96E1).
DIAGNOSIS USING DIAGNOSIS 2 MODE
1. Switch the diagnosis mode of the engine control unit to
DIAGNOSIS 2 mode using the MUT-
II .
2. Carry out a road test.
3. Take a reading of the diagnosis code and repair the
problem location.
4. Turn the ignition switch to OFF and then back to ON
again.
NOTE
By turning the ignition switch to OFF, the ENGINE-ECU
will switch the diagnosis mode from DIAGNOSIS 2 mode
to DIAGNOSIS 1 mode.
5. Erase the diagnosis codes.
INSPECTION USING MUT- II DATA LIST AND ACTUATOR
TESTING
1. Carry out inspection by means of the data list and the
actuator test function. If there is an abnormality, check
and repair the chassis harnesses and components.
2. After repairing, re-check using the MUT- II and check that
the abnormal input and output have returned to normal
as a result of the repairs.
3. Erase the diagnosis code memory.
4. Remove the MUT- II , and then start the engine again and
carry out a road test to confirm that the problem has
disappeared.
FREEZE FRAME DATA
When the engine-ECU detects a malfunction and stores a
diagnosis code, it also stores a current status of the engine.
This function is called “Freeze frame data.” By analyzing
this “freeze frame” data with the MUT-
II , an effective
troubleshooting can be performed.
The display items of freeze frame data are shown below.
