Notes:

1. Codes are only detected while the scan tool is connected. Up to four codes can be displayed at a time. Code numbers are on Page 35-15.
2. To erase codes with the MUT-I (not applicable to MUT-II), first connect the MUT-I directly to the battery for the test. Then display the Function Menu. Select "# 4 SPECIAL TEST". From the SPECIAL TEST menu, scroll to and select # 5 ERASE DIAG". Answer "YES" to the question "ERASE DIAG?". Choose "ID-NBR : 97" to erase codes four at a time. After erasing the DTCs, momentarily stop and restart the engine, and then reactivate the MUT-I.
3. When using scan tool in a road test, if a DTC is found, scan tool data will lock up and cannot be monitored further. Readings present at the time of the DTC will remain on the screen. Correct the DTC cause and then retest.
4. Diagnostics for Diamante Wagon are not included in the Diamante Wagon service manual. Refer to the 92-96 Diamante service manual for this information.
5. Diamante wheel speed sensors are fragile. To prevent damage, remove them when servicing the front end.






6. If the hydraulic unit has to be replaced, refer to pages 6-3 and 6-4 in the ABS Student Learning Guide for important accumulator handling precautions, some of which are included.
