Toyota Sienna Service Manual: Initialization
1. RESET MEMORY
The ECM memorizes the condition that the ECT controls the automatic transaxle assembly and engine assembly according to those characteristics. Therefore, when the automatic transaxle assembly, engine assembly, 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 engine switch off.
(b) Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
(c) Turn the ignition switch to the ON position and push the intelligent 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 (See page AX-9) described earlier.|
HINT: The ECM is learned by performing the ROAD TEST.
