Toyota Corolla Cross: Terminals Of Ecu
TERMINALS OF ECU
NOTICE:
- After the ignition switch is turned off, there may be a waiting time before
disconnecting the negative (-) auxiliary battery terminal.

- When disconnecting and reconnecting the auxiliary battery.
HINT:
When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.

- Before measuring the resistance of the CAN bus, turn the ignition switch off and leave the vehicle for 1 minute or more without operating the key or any switches, or opening or closing the doors. After that, disconnect the cable from the negative (-) auxiliary battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.
- This section describes the standard values for all CAN related components.
HINT:
- The systems (ECUs and sensors) that use CAN communication vary depending
on the vehicle and optional equipment. Check which systems (ECUs and sensors)
are installed to the vehicle.
Click here
- Operating the ignition switch, any other switches or a door triggers related ECU and sensor communication on the CAN. This communication will cause the resistance value to change.
- Even after DTCs are cleared, if a DTC is stored again after driving the vehicle for a while, the malfunction may be occurring due to vibration of the vehicle. In such a case, wiggling the ECUs or wire harness while performing the inspection below may help determine the cause of the malfunction.
