Scheme 327
Visual/Physical Inspection
- Inspect for aftermarket devices which can affect the operation of the power outlets. Refer to «Checking Aftermarket Accessories»(/cadillac/elr/i-2013-2015/remont/body-electrical/#wiring-systems-and-power-management-diagnostic-information-and-procedures__checking-aftermarket-accessories) .
- Inspect the accessible system components or the visible system components for obvious damage or for obvious conditions which can cause the symptom.
Intermittent
Electrical connections or wiring may be the cause of intermittent conditions. Refer to Testing for Intermittent Conditions and Poor Connections .
Symptom List
Refer to Power Outlet Receptacle Malfunction in order to diagnose the system.
Diagnostic Instructions
- Perform the «Diagnostic System Check - Vehicle»(/cadillac/elr/i-2013-2015/remont/oem-general-information/#vehicle-diagnostic-information-diagnostic-information-and-procedures) prior to using this diagnostic procedure.
- Review «Strategy Based Diagnosis»(/cadillac/elr/i-2013-2015/remont/oem-general-information/#vehicle-diagnostic-information-diagnostic-information-and-procedures__strategy-based-diagnosis) for an overview of the diagnostic approach.
- «Diagnostic Procedure Instructions»(/cadillac/elr/i-2013-2015/remont/oem-general-information/#vehicle-diagnostic-information-diagnostic-information-and-procedures__diagnostic-procedure-instructions) provides an overview of each diagnostic category.

| Ignition | 1 | 1 | ||
| Ground | 1 | |||
| 1. Accessory Power Receptacle Malfunction | ||||
Circuit/System Description
The vehicle is fitted with a 12 V accessory power receptacle. The accessory power outlets are controlled by an ignition operated relay. The accessory power receptacle is operational when Vehicle in Service Mode or Vehicle ON.
Diagnostic Aids
It may be helpful to discuss with the customer the usage of any device that may have drawn too much current and caused an open fuse.

Circuit/System Verification
- Vehicle in Service Mode, connect an appropriate device to the X80 Accessory Power Receptacle.
- Verify the device is powered by the X80 Accessory Power Receptacle. If the device is not powered Refer to Circuit/System Testing If the device is powered
- All OK.
Circuit/System Testing
- Vehicle OFF, disconnect the harness connector at the appropriate X80 Accessory Power Receptacle or E32 Cigarette Lighter Receptacle.
- Test for less than 10 ohms between the ground circuit terminal C and ground. If greater than 10 ohms Vehicle OFF. Test for less than 2 ohms in the ground circuit end to end. If 2 ohms or greater, repair the open/high resistance in the circuit. If less than 2 ohms, repair the open/high resistance in the ground connection. If less than 10 ohms
- Vehicle in Service Mode.
- Verify that a test lamp illuminates between the control circuit terminal A and ground. If the test lamp does not illuminate and the circuit fuse is good Vehicle OFF. Test for less than 2 ohms in the control circuit end to end. If greater than 2 ohms, repair the open/high resistance in the circuit. If less than 2 ohms, verify the fuse is not open and there is voltage at the fuse. Refer to «Retained Accessory Power Malfunction»(/cadillac/elr/i-2013-2015/remont/body-electrical/#wiring-systems-and-power-management-diagnostic-information-and-procedures) . If the test lamp does not illuminate and the circuit fuse is open Vehicle OFF. Test for infinite resistance between the control circuit terminal A and ground. If less than infinite resistance, repair the short to ground on the circuit. If infinite resistance, replace the appropriate X80 Accessory Power Receptacle. If the test lamp illuminates
- Replace the appropriate X80 Accessory Power Receptacle or E32 Cigarette Lighter Receptacle.
Repair Instructions
Perform the Diagnostic Repair Verification after completing the repair.
Accessory Power Receptacle Replacement
Special Tools
EL-42059 Cigar Lighter Socket Remover
For equivalent regional tools, refer to Special Tools .
Removal Procedure
- Remove the auxiliary power outlet fuse from the fuse block.
- Remove the receptacle: Look into the receptacle. There are two 3 mm (0.11 in) tab windows 12 mm (0.47 in) from the front of the receptacle. The EL-42059 remover pushes the plastic latches from these tab windows and the receptacle can be pulled straight out. Place one side of the "T" portion of the EL-42059 remover into the tab window. The EL-42059 remover will not fit straight into the receptacle. Angle the slightly for insertion into the receptacle. Insert the other side of the "T" into the opposite tab window. You must move the EL-42059 remover handle toward horizontal to engage the other tab window. Use the EL-42059 remover to pull the receptacle straight out.
- If EL-42059 remover tool fails to release the lighter socket from the retainer, perform the following alternate method: Insert a small grinding tool with a cutoff wheel into the socket. Remove the plastic latches in the 3 mm (0.11 in) square windows. Use the EL-42059 remover as directed above to remove the socket.
Installation Procedure
- Route the connector through the retainer. Align the accessory power receptacle retainer to the slot in the opening.
- Install the retainer by pressing into place fully seated.
- Connect the electrical connector to the receptacle.
- Align the tabs on the receptacle to the slots in the retainer. Install the accessory power receptacle by pressing into place until fully seated.
- Install the accessory power receptacle fuse.
12 Volt Power Outlet Receptacle Description and Operation
The accessory power receptacles and cigarette lighter receptacle are supplied with 12 V when the vehicle is in Service Mode or in Vehicle ON Mode.
