Co oznacza ten kod błędu?
The central electronic module (CEM) monitors the signal from the battery temperature sensor and has registered a signal that does not match. The sensor tells the system how warm the battery is, and when the reading is implausible the code is set. The fault may be permanent, or it may have occurred before and not be active right now.
Możliwe przyczyny
- Damaged battery temperature sensor
- Poor contact or open circuit in the sensor signal or ground wire
- Signal wire shorted to supply voltage
Co możesz zrobić
- 1Check that the battery is in good condition and that its terminals are tight
- 2Check that the sensor connector is fully engaged and free from oxidation
- 3Check the signal and ground wires for open circuits and chafing, especially where they are exposed to heat or movement
- 4Read the sensor value with diagnostic equipment; replace the sensor if it gives an implausible reading and the wiring is intact
Objawy, które możesz zauważyć2
- The battery discharges
- The fault usually gives no other clear symptoms
