Caution / Notice / Hint

NOTE:
  • The electric parking brake may still operate up to 20 seconds after the engine switch is turned off. Before disconnecting connectors or fuses, turn the engine switch off and wait 20 seconds or more.
  • When the electric parking brake switch assembly is pushed and held for 1 second or more without being pushed fully to the lock side, one of the 2 linked contacts may turn on while the other one turns off causing this DTC to be stored.
  • If the parking brake ECU assembly is replaced, perform the "Reset Memory" and "Acquire Tension Sensor Zero Point" procedures.
