What are the faults in the Accord electronic parking brake system?
2 Answers
Reasons for faults in the Accord electronic parking brake system: 1. The parking brake lever cannot be fixed; 2. The parking brake fails; 3. The parking brake makes abnormal noises or is aging; 4. The gap between the friction pads and the brake drum of the automatic parking system is too large, or the friction pads and brake drum are contaminated with oil, severely worn, have exposed rivets, or the surface is hardened, causing slippage and resulting in faults; 5. The parking brake pin shaft is severely worn, the gap is too large, or the parking brake lever adjustment is too long. Precautions for vehicle parking brake operation: 1. When parking on an inclined surface, if you shift to P position first and then engage the parking brake, the weight of the vehicle will make it difficult for the driver to shift out of P position when preparing to start the car; 2. When preparing to start the car, shift the gear lever out of P position before releasing the parking brake.
I've repaired quite a few Accord electronic parking brake issues, and found that the most common problems are switch or sensor contact failures. After prolonged use, sweat or dust can get inside and cause poor contact, resulting in unresponsive buttons or constant warning lights on the dashboard. Another issue is abnormal operation of the hydraulic pump or motor, such as motor jamming or lack of lubrication, causing slow operation with creaking noises. The most serious problem is internal circuit failure in the control module, essentially causing a system-wide brain short circuit. Last time I encountered a case where a car owner carelessly modified onboard equipment and burned out the wiring, leaving the motor completely unresponsive. Never delay with such issues - go straight to the dealership to scan for trouble codes. Electronic brake failure is a serious safety concern.
