Caution / Notice / Hint

WARNING: This page is about a different variant/trim than selected.
NOTE:
  • The electric parking brake may still operate up to 20 seconds after the ignition switch is turned off. Before disconnecting connectors or fuses, turn the ignition switch off and wait 20 seconds or more.
  • When the electric parking brake switch (integration control and panel assembly) is pulled and held for 1 second or more without being pulled 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 (system is not malfunctioning).
  • When replacing the parking brake ECU assembly, operate the electric parking brake switch (integration control and panel assembly) from the lock side to the release side, as the parking brake indicator light blinks when the ignition switch is first turned to ON.
