Circuit/System Verification

WARNINGTo help avoid personal injury, always treat the accessory power receptacle, accessory DC/AC power inverter module, AC circuit wires, and connectors as if AC high-voltage is present.
  1. Ignition OFF, test for 12.0-15.0 V across the battery terminals. If not within the specified range, refer to «Battery Inspection/Test»(ref-364485-S24273982112010063000000) .
  2. Ignition ON, connect an AC power extension cord to the X81 accessory power receptacle - 110 V AC. Inserting the extension cord plug into the X81 accessory power receptacle - 110 V AC turns the T1 accessory DC/AC power inverter module ON.
  3. Verify the receptacle indicator light comes ON.
  4. Test for 110-120 V between the terminals of the extension cord.
  5. Test for 59-61 Hz AC between the terminals of the extension cord.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

Tools Required

J 42059 Cigar Lighter Socket Remover. See Special Tools .

110 Volt Power Outlet Receptacle Isolation Fault Protection

The accessory DC/AC power inverter module contains a ground fault circuit interrupter (GFCI). GFCI monitors the 110 V circuit for a short to vehicle chassis ground. If a 110 V AC short to ground is detected, the accessory DC/AC power inverter 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.

110 Volt Power Outlet Receptacle Overload Shutdown

The accessory DC/AC power inverter module will turn OFF if the current in the 110 V circuit is greater than 3.8 A for 1 second, or 2.5 A 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.

110 Volt Power Outlet Receptacle Internal Shutdown

The accessory DC/AC power inverter module will turn OFF if the B+ supply voltage is greater than 16.5 V or less than 11 V. The module will also turn OFF if the device temperature is greater than 85°C (185°F). The module will turn ON again, after the shutdown condition is corrected, and the AC powered device is unplugged from the outlet, and then plugged into the outlet.
