Vehicle Stability Control System: Precaution
NOTE:
When disconnecting the cable from the negative (-) battery terminal, initialize the following system after the cable is reconnected.
SYSTEM NAME CHART
| System Name | See procedure |
|---|---|
| Front power seat control system (w/ Memory) | INITIALIZATION |
| Meter gauge system | CALIBRATION |
CAUTION:
- When there are problems with contact points of terminals and improper part installation, the installation / removal of the suspected part may return the system to normal or may only temporarily return the system to normal.
- To determine the malfunctioning area, use DTCs, freeze frame data and other data to help determine conditions at the time of the malfunction. Write down the data before disconnecting connectors or installing / removing parts.
- The vehicle stability control system may be affected by malfunctions in other systems. Check for DTCs in other systems and, if present, troubleshoot those DTCs first.
- Unless specified, the ignition switch must be OFF when installing / removing the brake actuator and the vehicle stability control system's connectors.
- After the brake actuator or a vehicle stability control system connector has been removed and reinstalled, be sure to check for DTCs. Also, perform the test mode inspection to make sure the part is functioning normally.
- After replacing the yaw rate sensor and / or the skid control ECU, make sure to perform the yaw rate sensor and deceleration sensor zero point calibration.
- Since the CAN communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.
