Check Bus 4 Line for Short to +B [10/2022 - 10/2023]: Description
There may be a short circuit between one of the CAN bus lines and +B when there is no resistance between terminal CA2H of the central gateway ECU (network gateway ECU) and terminal BAT of the DLC3, or terminal CA2L of the central gateway ECU (network gateway ECU) and terminal BAT of the DLC3.
| Symptom |
Trouble Area |
- There is no resistance between terminal 22 (CA2H) of the central gateway ECU (network gateway ECU) and terminal 16 (BAT) of the DLC3, or terminal 7 (CA2L) of the central gateway ECU (network gateway ECU) and terminal 16 (BAT) of the DLC3.*1
- There is no resistance between terminal 24 (CA2H) of the central gateway ECU (network gateway ECU) and terminal 16 (BAT) of the DLC3, or terminal 23 (CA2L) of the central gateway ECU (network gateway ECU) and terminal 16 (BAT) of the DLC3.*2
