Co oznacza ten kod błędu?
The ECM compares the brake light switch with the brake pedal switch. If the two show different states for a set period, fault code ECM-1828 is set. Cars without cruise control have only the brake light switch, which is operated by the brake pedal.
Możliwe przyczyny
- Signal wire to the brake pedal switch shorted to voltage
- Open circuit in the signal wire to the brake pedal switch
- Signal wire to the brake light switch shorted to voltage
- Switch at the brake pedal incorrectly fitted or adjusted
- Defective brake pedal switch or brake light switch
Co możesz zrobić
- 1Switch off the ignition and check that the brake light switch and the brake pedal switch are correctly fitted and free of play and oxidation
- 2With a multimeter, check that the signal wires from the switches are not shorted to voltage and are not broken
- 3If you have a diagnostic tool: check in live data that the brake light switch and the brake pedal switch change together as the pedal is pressed and released
- 4Braking is safety-critical. If the pedal feels different or the brake lights stay on, do not drive the car until a workshop has checked the braking system
- 5If the fault remains, have a workshop adjust or replace the switches at the brake pedal
Objawy, które możesz zauważyć2
- Cruise control does not work at all
