What does it mean?
P1653 is a Powertrain (engine, transmission, fuel system) fault code. It indicates: Please Check DTC Memory of the ABS Control Module .
Symptoms
- MIL on together with ABS and stability control warning lamps
- Traction and stability control disabled, and no anti-lock action during hard braking
- Speedometer or trip computer readings behaving oddly on some vehicles
- Transmission shifting harshly because it no longer trusts wheel speed data
- Codes visible in the ABS module when it is scanned separately
Likely causes
- A genuine fault stored in the ABS/stability module, most often a wheel speed sensor circuit
- Damaged reluctor ring, or debris and rust on a wheel speed sensor tip
- ABS pump motor or valve solenoid fault inside the hydraulic unit
- Low brake fluid or a faulty brake light switch upsetting the stability system
- Poor power or ground supply to the ABS module, or an internal module fault
- Weak battery causing spurious ABS faults during cranking
- ABS module replaced without coding, or a communication problem with the engine module
How to fix it
- Read the ABS/stability module's own fault memory first; that is exactly what this code is asking you to do
- Work through the ABS codes by priority, starting with wheel speed sensor circuits, which are the most common
- Compare all four wheel speed values on live data during a slow drive and look for one that drops out
- Inspect the wheel speed sensor connectors, cables and reluctor rings for rust, debris, cracks and wheel bearing play
- Check battery condition and the ABS module power and ground with voltage-drop tests
- Clear both fault memories, road test, and see which code returns first
- Repair, replace and code the ABS module only after sensors, wiring and supply are proven good
