DESCRIPTION The parking
brake ECU (brake actuator assembly) receives vehicle tilt angle
information from the deceleration sensor (airbag ECU assembly) via CAN
communication. |

Memory | Note | |
C1245 | Deceleration Sensor |
One of following conditions is met:
- An error signal is sent from deceleration sensor (airbag ECU assembly) for approximately 0.3 seconds.
- While the deceleration sensor (airbag ECU assembly) signal is judged to
be stuck, starting off and stopping of vehicle occurs 16 times.
- Comparison error between deceleration sensor (airbag ECU assembly) 1 and
deceleration sensor (airbag ECU assembly) 2 output values occurs for 60
seconds or more.

| 2. |
CHECK DTC (ELECTRIC PARKING BRAKE SYSTEM) |
(a) Clear the DTCs. Chassis > Electric Parking Brake > Clear DTCs
(b) Turn the power switch off. (c) Check for DTCs. Chassis > Electric Parking Brake > Trouble Codes
|
Result | Proceed to | |
DTCs are output | A | |
DTCs are not output | B |
| A |
| REPLACE AIRBAG ECU ASSEMBLY |
| B |
| USE SIMULATION METHOD TO CHECK | |
