DTC stored | An electric parking brake system malfunction is displayed on the multi-information display. |
If the electric parking brake switch is held near the lock position but not fully in the lock position for 1 second or more, a DTC may be stored due to one of the two contacts being ON while the other is OFF. (This is not a system malfunction.)
The electric parking brake may still operate up to 4 minutes after the ignition switch is turned off. Before disconnecting connectors or fuses, turn the ignition switch off and wait 4 minutes or more.
After replacing the skid control ECU (brake actuator assembly), perform acceleration sensor zero point calibration and store system information memorization.
When replacing the skid control ECU (brake actuator assembly), operate the electric parking brake switch (electric parking brake switch assembly) as the parking brake indicator light (red) blinks when the ignition switch is first turned ON.
Operate the electric parking brake switch (electric parking brake switch assembly) and check that the value of "EPB Switch" in the Data List changes between Lock and Release in accordance with the operation of the switch.
| Tester Display | Measurement Item | Range | Normal Condition | Diagnostic Note |
|---|---|---|---|---|
| EPB Switch | Electric parking brake switch (electric parking brake switch assembly) input | OFF / Lock / Release / Unknown | OFF: Lock switch and release switch are off
Lock: Lock switch on Release: Release switch on |
When not normal, electric parking brake switch (electric parking brake switch assembly) release side system may be malfunctioning
