DESCRIPTION
B2321 is stored when the communication between the power window regulator master switch assembly and the main body ECU (network gateway computer) stops for 10 seconds or more.
The main body ECU (network gateway computer) monitors communication between all the ECUs connected to the door LIN bus. When the main body ECU (network gateway computer) detects errors in communication with all the ECUs connected to the door LIN bus at 2.6-second intervals and 3 times in a row, DTC B2325 will be stored.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2321 | Lost communication between the multiplex network master switch assembly and the main body ECU (network gateway computer). | Power window regulator master switch assembly Main body ECU (network gateway ECU) Harness or connector |
| B2325 | The main body ECU (network gateway computer) detects errors in door LIN bus communication lines at 2.6-second intervals and 3 times in a row. | Power window regulator master switch assembly Main body ECU (network gateway ECU) Harness or connector |
Scheme 93
The certification ECU (smart key ECU assembly) monitors the communications with the steering lock actuator assembly (steering lock ECU) connected to the certification LIN bus and the ID code box (immobiliser code ECU)*. DTC B2785 is stored if the certification ECU (smart key ECU assembly) detects a communications error between the steering lock actuator assembly (steering lock ECU) connected to the certification LIN bus and the ID code box (immobiliser code ECU), and the LIN communications error (+B short, GND short, communication not possible because of noise, etc.) continues for 1 second.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2785 | The certification ECU (smart key ECU assembly) detects a LIN communication error (+B short, GND short, communication not possible because of noise, etc.) that continues for 1 second. | Certification ECU (smart key ECU assembly) Steering lock actuator assembly (steering lock ECU) ID code box (immobiliser code ECU)* Harness or connector |
* : w/ ID Code Box
Scheme 94
This DTC is stored when the communication between the certification ECU (smart key ECU assembly) and the steering lock actuator assembly (steering lock ECU) stops for more than 10 seconds.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2786 | This DTC is stored when communication between the certification ECU (smart key ECU assembly) and the steering lock actuator assembly (steering lock ECU) stops for more than 10 seconds. | Steering lock actuator assembly (steering lock ECU) Certification ECU (smart key ECU assembly) Harness or connector |
Scheme 95
This DTC is output when the LIN communication between the certification ECU (smart key ECU assembly) and the ID code box (immobiliser code ECU) stops for more than 10 seconds.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B2789 | No communication between the certification ECU (smart key ECU assembly) and the ID code box (immobiliser code ECU) for more than 10 seconds | ID code box (immobiliser code ECU) Certification ECU (smart key ECU assembly) Harness or connector |
