Avalon V6-3.0L (1MZ-FE) (1996)
Step 3
Electronically Controlled Transmission Communication Circuit
Electronically Controlled Transaxle Communication Circuit
CIRCUIT DESCRIPTION
When driving uphill under cruise control, in order to reduce shifting due to ON-OFF overdrive operation and to provide smooth driving, when down
shifting in the electronic control led transaxle occurs, a signal to prevent upshift until the end of the uphill slope is sent from the cruise control ECU to
the electronic controlled transaxle.
Terminal ECT of the cruise control ECU detects the shift change signal (output to electronic controlled transaxle No.2 solenoid) from the electronically
controlled transaxle.
If vehicle speed down, also when terminal electronically controlled transaxle of the cruise control ECU receives down shifting signal, it sends a signal
from terminal OD to OD1 to cut overdrive until the end of the uphill slope, and the gear shifts are reduced and gear shift points in the electronically
controlled transaxle are changed.
