Circuit/System Verification
- Vehicle in Service Mode, verify no additional DTCs are set in other control modules.
- If additional DTCs are set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- Go to next step: If no additional DTCs are set
- If additional DTCs are set
- Verify DTCs that disable DC Charging were not recently cleared.
- If DTCs were cleared
Perform the Clear Secured High Voltage DTCs .
- Go to next step: If DTCs were not cleared or the DC Charging Disable Reset had been Performed
- If DTCs were cleared
- Verify that a low/no 12V Condition was not present at the K16A Battery Energy Control Module 1 or that the module was not recently programmed.
- If the specified conditions occurred
The vehicle must be driven at a speed Greater than 3 km/h (2 mph) to re-enable DC Charging.
- Go to next step: If the specified conditions had not occurred or the vehicle had been driven
- If the specified conditions occurred
- Connect a 120/220V AC charge cord and verify the vehicle will AC charge.
- If the vehicle will not AC Charge
Refer to the AC Charging document Plug-In Charging Malfunction (AC Charging) Plug-In Charging Malfunction (DC Charging) .
- Go to next step: If the vehicle will AC Charge
- If the vehicle will not AC Charge
- Review the K16A Battery Energy Control Module 1, DC Charge History Scan Tool Parameters. Inspect for any conditions that prohibited DC Charging.
- If an off-vehicle charge station Condition prohibited DC Charging
The vehicle is OK. Advise the customer to report a problem with the DC fast charge station.
- Go to next step: If an off-vehicle Condition was not observed
- If an off-vehicle charge station Condition prohibited DC Charging
- Verify with the customer whether the off-vehicle DC Charge Station had multiple charge cords, or they had difficulty in connecting the charge cord to the receptacle.
- If any of the conditions were observed
The vehicle is OK. Advise the customer to report a problem with the DC fast charge station.
- Go to next step: If the conditions were not observed
- If any of the conditions were observed
- Connect to a known good DC Charge Station. Verify vehicle will fast charge and no DTCs are set.
- If the vehicle will not fast charge and DTCs are set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- If the vehicle will not fast charge and no DTCs are set
Refer to Circuit/System Testing.
- Go to next step: If the vehicle will fast charge
- If the vehicle will not fast charge and DTCs are set
- All OK.
Always inspect for debris in both the Coupler and the charge cord that might prevent complete insertion. Snow/Ice, insects or other foreign material may prevent good electrical connection and should be removed before attempting to diagnose charging complaints.
Certain DTCs inhibit DC Charging, clearing the DTC alone will not clear the inhibit condition.
Loss of 12V or programming of the module will inhibit DC Charging.
The DC Charge History parameters record the conditions present during the last 5 charge events.
Review diagnostic aids.
