Toyota Corolla Repair Manual: Inspection procedure
1 Inspect transmission wire(s1)
- Disconnect the transmission wire connector from the transaxle.
- measure the resistance according to the value(s) in the table below.
Standard:
2 Check harness and connector(transmission wire – ecm)
- Connect the transmission connector to the transaxle.
- disconnect the connector from the ecm.
- measure the resistance according to the value(s) in the table below.
Standard:
Replace ecm
3 Inspect shift solenoid valve(s1)
- Remove the shift solenoid valve s1.
- measure the resistance according to the value(s) in the table below.
Standard:
- Connect the positive (+) battery lead to the solenoid connector terminal, and the negative (–) battery lead to the solenoid body for checking the solenoid valve operation.
Standard: the solenoid makes an operating noise.
Repair or replace transmission wire
Circuit description
Shifting from 1st to o/d is performed in combination with on and off of the
