DTC Information And Inspection: DTC Detecting Condition
WARNING: This page is about a different variant/trim than selected.
| Troubleshooting |
Condition |
Possible Cause |
| Main Action |
|
- Poor contact of connector
- Controller power supply failure
- Faulty IEBM
|
| Threshold Value |
Case 1 (EPB power) |
- A failure is detected when the voltage of motor supply power is lower than 4V for 150 milliseconds
|
| Case 2 (EPB Current Sensor Error) |
- A failure is detected when the current difference between main and sub is over than 5A for 200 milliseconds during motor driving
- A failure is detected when the current is greater than |2|A during motor non-driving
|
| Case 3 (EPB Pre-drive FET Error) |
- A failure is detected when the VMTP is over than 1V for 200 ms in case that the High side FET is off and Low side FET is ON
- A failure is detected when the motor voltage is 3V lower than to EPB motor power supply voltage for 200 milliseconds, while high side FET is on and low side FET is OFF
- A failure is detected when the FET Vds is out of a specified value for 100 milliseconds
- A failure is detected when a difference between FET state measured in EPB Driver IC and programmed value by SPI is detected for 100 milliseconds
|
| Case 4 (EPB Driver HW Error) |
- A failure is detected when the internal faults of driver IC are detected for 100 milliseconds
- A failure is detected when the abnormal internal power supply is detected for 100 milliseconds
|
| MIL |
- AVH/EPB warning lamps are activated
|
| Reset Condition |
- When the normal state is confirmed after ignition switch turned OFF and back ON
