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 the ignition is turned to either the On or the Accessories positions.

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

Ignition ON, 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

Ignition OFF, disconnect the harness connector at the appropriate X80 Accessory Power Receptacle. It may take up to 2 min for all vehicle systems to power down.
Test for less than 10 Ω between the ground circuit terminal C and ground.

If greater than 10 Ω

Ignition OFF.
Test for less than 2 Ω in the ground circuit end to end.

If 2 Ω or greater, repair the open/high resistance in the circuit.
If less than 2 Ω, repair the open/high resistance in the ground connection.

If less than 10 Ω

Ignition ON.
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

Ignition OFF.
Test for less than 2 Ω in the control circuit end to end.

If greater than 2 Ω, repair the open/high resistance in the circuit.
If less than 2 Ω, verify the fuse is not open and there is voltage at the fuse. Refer to Retained Accessory Power Malfunction.

If the test lamp does not illuminate and the circuit fuse is open

Ignition 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

Test or replace the X80 Accessory Power Receptacle.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.

Accessory Power Receptacle Replacement.

Visual/Physical Inspection

Inspect for aftermarket devices which can affect the operation of the power outlets.
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.
