15. RESET MEMORY
CAUTION:
Perform the RESET MEMORY (AT initialization) when replacing the automatic transaxle assy, engine
assy or the ECM.
NOTICE:
Hand−held tester only
HINT:
The ECM memorizes the condition that the ECT controls the automatic transaxle assy and engine assy ac-
cording to those characteristics. Therefore, when the automatic transaxle assy, engine assy, or ECM has
been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.
Reset procedure is as follows.
(a) Turn the ignition switch off.
(b) Connect the hand−held tester to the DLC3.
(c) Turn the ignition switch to the ON position and push the hand−held tester main switch on.
(d) Select the item "DIAGNOSIS/ENHANCED OBD II".
(e) Perform the reset memory procedure from the ENGINE menu.
CAUTION:
After performing the RESET MEMORY, be sure to perform the ROAD TEST described earlier.
