Causes

Blown fuse or tripped circuit breaker protecting the DC/AC converter/outlet
Open, damaged, corroded or disconnected wiring/connector in the outlet supply or ground circuit
Faulty outlet socket or internal connector failure
Faulty DC/AC converter module or internal relay/solid-state switch
Body control module or power management module output driver failure
Water intrusion or physical damage at the outlet or harness

Symptoms

High-voltage AC outlet "D" does not provide power or is intermittent
Related outlet indicator (if fitted) shows off or fault
No voltage present at outlet terminals when enabled
Possible stored additional codes for converter or body module
Normal vehicle driveability usually unaffected (electrical accessory only)

What to check

Retrieve freeze frame and any additional codes from the body/control modules
Visually inspect outlet, socket, and surrounding area for corrosion, debris or water
Check fuse(s) and circuit breaker(s) for the converter/outlet (replace if blown)
Inspect wiring harness and connectors for damage, loose pins, or corrosion
Measure presence of supply voltage and ground at the outlet connector with ignition/accessory on
If available, use manufacturer diagnostic data to verify expected AC output when converter enabled

Signal parameters

Battery supply voltage at converter input: ~vehicle battery voltage (approx. 12–14 V) with ignition on
Supply voltage at outlet connector: should match converter output presence when enabled (see vehicle spec for AC voltage)
Connector continuity to converter: near 0 ohms to supply and ground (open = infinite/OL)
Ground resistance: typically
Control signal from body/power module to converter enable: correct switched voltage or logic signal per manufacturer spec

Diagnostic algorithm

Read and record all related codes and module data. Note ignition state required for tests.
Perform a visual inspection of the outlet (socket D), wiring, and connectors for corrosion, water, or physical damage.
Check relevant fuse(s) and circuit breaker(s) for the DC/AC converter/outlet circuit. Replace blown fuses and retest.
With ignition/accessory on and converter commanded ON, measure supply voltage at the outlet connector and at the converter input. If no supply, trace back toward fuse and battery.
Check continuity between the converter output terminal and the outlet terminal. Repair any open or high-resistance wiring/connectors.
Verify good chassis ground at converter and outlet ground points; repair or clean grounds if high resistance.
Wiggle test harness and connectors while monitoring voltage to reproduce intermittent faults.
If wiring and fuses are good, check the converter enable/control signal from the body/power module (voltage or data command). If no enable signal, investigate module or communications.
If enable signal is correct and supply/ground are present but outlet still has no output, suspect converter module or outlet socket failure — bench test or replace per service manual.
After repairs, clear codes and verify operation under normal conditions; test for reoccurrence and perform final inspection for moisture or damage.

Likely causes

Open or corroded connector at the outlet (most common)
Blown fuse or tripped/resettable breaker in the DC/AC converter feed
Damaged harness between converter and outlet (pinched, chafed, or disconnected)
Failed DC/AC converter internal switch or control electronics
Poor ground connection at converter or chassis ground stud

Fault status

⚠️ Status

Open/high-resistance detected in DC/AC Converter A High Voltage Power Outlet "D" circuit — outlet may be dead or intermittent. Inspect fuses, wiring, connectors, grounds, and converter module.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-2.0 hours
