Toyota Corolla Repair Manual: Circuit description

When driving uphill under cruise control, in order to reduce the number of shifting due to onoff overdrive operation and to provide smooth driving, when down shifting in the electronically controlled transmission occurs, a signal to prevent upshift until the end of the uphill slope is sent from the cruise control ecu assy to the electronically controlled transmission.

Terminal ect of the cruise control ecu assy detects the shift change signal (output to electronically controlled transmission no.2 Solenoid) from the ecm.

If the vehicle slows down, also when terminal ect of the cruise control ecu assy receives down shifting signal, it sends a signal from terminal od to ecm to cut overdrive until the end of the uphill slope, and the number of gear shifts are reduced and gear shift points in the electronically controlled transmission are changed.

Symptom confirmation and diagnostic trouble code
Hint: the diagnostic system in corolla has various functions. The first function is the diagnostic trouble code (dtc) check, in which a malfunction in the signal circuits to the ecu is stored in code form in the ecu memory. Another function is the input signal check, which checks if ...
