Caution / Notice / Hint
NOTE:
- Inspect the fuses for circuits related to this system before performing the following procedure.
- Before measuring the resistance of the CAN bus, turn the engine 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 (-) battery terminal and leave the vehicle for 1 minute or more before measuring the resistance.
- After the engine switch is turned off, there may be a waiting time before disconnecting the negative (-) battery terminal.
Refer to BEFORE DISCONNECTING BATTERY [10/2020 - 10/2022] , or refer to BEFORE DISCONNECTING BATTERY [10/2022 - 10/2023]
- When disconnecting and reconnecting the battery
Refer to WORK PROCEDURE [10/2020 - 10/2022] , or refer to WORK PROCEDURE [10/2022 - 10/2023]
HINT:
When disconnecting and reconnecting the battery, there is an automatic learning function that completes learning when the respective system is used.
HINT:
- Operating the engine 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.
