page 19 (Energy Management Calibration)
X503 System connector faulty
• Check the mechanical appearance of the connector
• Clean the contacts on the board or change the connector if necessary
F100 faulty
• Check resistance of F100 (0 Ω )
• Check the resistance V_charge line to ground (OK=10K Ω )
N100 CCONT faulty/ poor soldering
• Check if any A/D values are out of limit but the corresponding DC voltages is OK (wintesla/ local mode/ Testing/
ADC Readings…)
• If DC voltages are wrong, check corresponding voltage dividers (R100, R101)
• Check PWMOUT on R117 or R142 (1 Hz standard / 32 Hz fast)
R103 broken and N101 PSCC electrical faulty
• Check if the handset doesn't charge with the ACP-9 fast charger
• Check the mechanical appearance of the varistor R103
• If it's broken change it, in this case change also N101 PSCC
R125 and R127 connection faulty
• Check if any A/D value is out of limit special BTEMP (317 ≅ 25°)
• Check the connection between R125 and R127
• Check the NTC resistor R127 47K Ω
