C0265 C0xxx · 底盘（C） 高严重度
ABS/ESP Control Module Relay or Power Circuit
The ABS module's power supply or internal relay is not behaving. A supply problem masquerading as a module failure in most cases.
严重程度说明： 高——立即停车诊断，继续行驶有扩大损坏的风险
你会注意到的故障现象
- ABS lamp on
- Module not communicating
- Multiple chassis codes at once
常见原因
按可能性从高到低排列——从最上面开始查。
- 1 Blown fuse or failed relay
- 2 Corroded connector at the modulator
- 3 Poor earth
- 4 Internal module fault
如何排查
先做花钱最少、侵入最小的检查——大多数这类码不是零件问题。
- ✓ Check every ABS-related fuse and relay before anything else.
- ✓ Measure voltage drop on the module supply and earth under load.
- ✓ Inspect the connector for water ingress — ABS connectors live in a harsh location.
- ✓ Only then consider module replacement.
维修方案
- Replace the fuse or relay
- Repair the wiring or earth
- Replace the module if genuinely failed
C0265 —— 常见问题
Several chassis codes appeared at once — why? +
A shared power or earth fault. Do not chase each code individually; fix the supply first.
Is water ingress common? +
Yes, especially where the connector sits low in the engine bay. Seal it after repair.
