DTC B3205 0B
- Window Motor Fast Over Current Fault

Diagnostic Fault Information






Circuit/System Description

The passenger door module (PDM) and driver door module (DDM) control the power window functions through the power window motor up and down control circuits. The PDM/DDM monitors the control circuits for fault conditions when the up or down operation is requested prior to activating the function and during the operation.

Conditions for Running the DTC

* Battery voltage must be between 9-16 volts.
* The ignition switch is in the ON position

Conditions for Setting the DTC

B3205 00

The PDM detects a short to ground or short to voltage on a window motor control circuit.

B3205 0B

During 5 occurrences of power window motor operation in an ignition cycle, the PDM/DDM has detected excessive current flow on a window motor control circuit.

Action Taken When the DTC Sets

The passenger power window will be inoperative until the DTC is cleared.

Conditions for Clearing the DTC

The PDM/DDM will clear the history DTC after 50 fault free ignition cycles, or in response to a scan tool command.

Diagnostic Aids

The DTC B3205 0B can be set due to excessive physical resistance in the window regulator assembly. Ensure proper mechanical operation of the regulator assembly prior to replacing electrical components.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the passenger window motor.
2. Ignition OFF, test for less than 1.0 ohm of resistance between the control circuit terminal A and ground.

^ If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If circuits test normal, replace the PDM /DDM.

3. Ignition OFF, test for less than 1.0 ohm of resistance between the control circuit terminal B and ground.

^ If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance. If circuits test normal, replace the PDM/DDM.

4. Connect a test lamp between control circuit terminal A and control circuit terminal B.
5. Ignition ON, command the passenger window UP and DOWN by pressing the passenger window switch. The test lamp should turn ON when commanding the UP and DOWN states.

^ If the test lamp remains OFF during either of the commands, test for a short to ground on either control circuit. If the circuits test normal, replace the PDM/DDM.

6. If all circuits test normal, test or replace the passenger window motor.

Component Testing

1. Install a 25-amp fused jumper wire between the control terminal A and 12 volts. Momentarily install a jumper wire between the control terminal B and ground. The passenger window motor should perform the UP or DOWN function.

^ If the function does not perform as specified, replace the appropriate Window Motor.

2. Reverse the jumper wires; the passenger window motor should perform the DOWN or UP function.

^ If the function does not perform as specified, replace the passenger window motor.
