Kia Cee'd: Charging System / Battery Sensor Repair Procedures

Removal

1
Disconnect the negative (-) battery cable.
2
Disconnect the battery sensor connector (A).
3
Disconnect the negative (-) battery cable after removing the bolt.

Installation

Install in the reverse order of removal. Battery sensor cable bolt: 10.8 ~ 13.7 N·m Battery (-) terminal nut: 3.9 ~ 5.9 N·m
NOTE
- After reconnecting the negative battery cable, the AMS and ISG function do not operate until the system stabilizes, approximately 4 hours. When disconnecting the negative (-) battery cable from the battery during repair work on a vehicle equipped with the ISG function, the battery sensor recalibration procedure should be performed after the repair work is completed. (Refer to Battery Sensor Recalibration Procedure)
NOTE
- For vehicles equipped with a battery sensor, be careful not to damage the battery sensor when the battery is replaced or recharged.
1. When replacing the battery, it must be the same type, capacity and brand as originally installed on your vehicle. Installing a battery of a different type may cause the battery sensor to detect a battery malfunction.
2. When installing the ground cable to the battery negative terminal, tighten the clamp to the specified torque. Excessive tightening torque may damage the internal printed circuit board, circuits and battery terminals.
3. When charging the battery, ground the negative terminal of the auxiliary battery to the vehicle body.

Inspection

1
Check for DTCs.
NOTE
- If a diagnostic trouble code is present, perform troubleshooting in accordance with the procedure for that DTC. (Refer to the Diagnostic Trouble Code Manual)
2
Check whether the battery sensor condition is normal using the current data with GDS. If its value is ON, replace the battery sensor.
- Battery sensor (AMS) condition is abnormal = OFF.
NOTE
- The battery sensor may operate abnormally if the parasitic current exceeds 100 mA. Therefore, if a battery sensor signal error occurs, check the vehicle parasitic current before replacing the battery sensor. (Refer to Charging System - Battery)

Adjustment

Battery Sensor Recalibration Procedure

When disconnecting the negative (-) battery cable from the battery during repair work on a vehicle equipped with the Alternator Management System (AMS), the battery sensor recalibration procedure must be performed after the repair work is completed.

1
Turn the ignition switch ON and OFF.
2
Park the vehicle for approximately 4 hours in the following conditions.
- Park the vehicle for approximately 4 hours in the following conditions.
- Close the hood, trunk, and all doors.
3
After 4 hours, check whether the current data is displayed normally using GDS.
- Rated capacity (AMS) = 45 Ah [for non-ISG type]
- Rated capacity (AMS) = 60 Ah [for ISG type or Russia region]
- Battery state of charge (AMS) = (0~100%)
- Battery condition (AMS) = (0~100%)
4
After cranking the engine 2 or more times, check the "Battery Functional Status" (AMS) = (0~12 V). [ISG system only]
