Diagnostic Starting Point - Power Outlets

Begin the system diagnosis by reviewing the Power Outlets Description and Operation . Reviewing the Description and Operation will help to determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the Description and Operation information will also help to determine if the condition described by the customer is normal operation. Refer to Symptoms - Power Outlets in order to identify the correct procedure for diagnosing the system and where the procedure is located.

Circuit/System Description

The accessory AC/DC power control module converts 12 volt direct current (DC) battery voltage to 110-120 volt alternating current (AC) in order to operate AC powered devices. The accessory AC/DC power control module provides up to 150 watts of power. The accessory AC/DC power control module is connected to a chassis ground circuit and receives fuse protected battery voltage.

The accessory power outlet has an internal switch, that detects when an AC powered device is plugged into the outlet. When the ignition is ON and a 120 volt AC powered device is plugged into the accessory power outlet, the normally-open switch in the accessory power outlet, closes. When the accessory AC/DC power control module detects the voltage from the accessory power outlet switch, the inverter module begins to supply 110-120 volts AC to the accessory power outlet after a 1.5 second delay.

Diagnostic Aids

A household 120 volt duplex receptacle outlet tester should not be used to diagnose this system. The tester will indicate an open ground, which is a normal condition.

Tools Required

J 42059 Cigar Lighter Socket Remover. See Special Tools .

Removal Procedure

  1. Remove the auxiliary power outlet fuse from the fuse block.
  2. 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 J 42059 pushes the plastic latches from these tab windows and the receptacle can be pulled straight out. See «Special Tools»(/chevrolet/avalanche/ii-2006-2013/remont/body-electrical/#accessory-power-socket__special-tools) . Place one side of the "T" portion of the J 42059 into the tab window. See «Special Tools»(/chevrolet/avalanche/ii-2006-2013/remont/body-electrical/#accessory-power-socket__special-tools) . The J 42059 will not fit straight into the receptacle. See «Special Tools»(/chevrolet/avalanche/ii-2006-2013/remont/body-electrical/#accessory-power-socket__special-tools) . Angle the J 42059 slightly for insertion into the receptacle. See «Special Tools»(/chevrolet/avalanche/ii-2006-2013/remont/body-electrical/#accessory-power-socket__special-tools) . Insert the other side of the "T" into the opposite tab window. You must move the J 42059 handle toward horizontal to engage the other tab window. See «Special Tools»(/chevrolet/avalanche/ii-2006-2013/remont/body-electrical/#accessory-power-socket__special-tools) . Use the J 42059 to pull the receptacle straight out. See «Special Tools»(/chevrolet/avalanche/ii-2006-2013/remont/body-electrical/#accessory-power-socket__special-tools) .
  3. If J 42059 tool fails to release the lighter socket from the retainer, perform the following alternate method:. See «Special Tools»(/chevrolet/avalanche/ii-2006-2013/remont/body-electrical/#accessory-power-socket__special-tools) . 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 J 42059 as directed above to remove the socket. See «Special Tools»(/chevrolet/avalanche/ii-2006-2013/remont/body-electrical/#accessory-power-socket__special-tools) .

System Description

The alternating current (AC) accessory power outlet system consists of the accessory AC/DC power control module and the accessory power outlet. The accessory AC/DC power control module converts 12 volt direct current (DC) battery power to 110-120 volts AC power to operate AC powered devices. The power inverter module within the accessory AC/DC power control module provides up to 150 watts of power. The accessory power outlet is designed to accept two and three prong 110-120 volt power cords. The accessory power outlet provides the usual hot and neutral line circuits. The neutral circuit is isolated from the chassis ground. The center terminal receptacle is empty and does provide a circuit ground.

System Operation

The accessory AC/DC power control module receives fuse protected battery voltage and is connected to the 12 volt electrical system ground. The accessory power outlet has an internal switch, that detects when an AC powered device is plugged into the outlet. When the ignition is ON, and a 120 volt AC powered device is plugged into the accessory power outlet, the normally open switch in the accessory power outlet, closes. When the accessory AC/DC power control module detects the voltage from the accessory power outlet switch, the inverter module begins to supply 110-120 volts AC to the accessory power outlet after a 1.5 second delay. An LED indicator in the accessory power outlet illuminates when the outlet is receiving AC voltage. The accessory AC/DC power system is protected against circuit overload and circuit shorts to ground.

Isolation Fault Protection

The accessory AC/DC power control module contains a ground fault circuit interrupter (GFCI). GFCI monitors the 110 volt AC circuit for the following conditions

  1. The hot circuit or the neutral circuit becomes shorted to the vehicle chassis ground
  2. The current flow through the hot circuit and the neutral circuit differs from each other by greater than 6 mA

If either of the above conditions is detected, the accessory AC/DC power control module will turn OFF. The module remains OFF, until the AC powered device is unplugged from the outlet, and then plugged into the outlet after a 3 second delay.

Overload Shutdown

The accessory AC/DC power control module will turn OFF if the current in the 110 volt circuit exceeds 3.8 amps for 1 second, or 2.5 amps for 10 seconds. The module will turn ON again, when the AC powered device is unplugged from the outlet, and then plugged into the outlet after a 3 second delay.
