||||||||||||||||||||||||||||||
Circuit/System Description
When a window switch is pressed on the driver window switch, a serial data message is sent to the body control module (BCM). The BCM examines the request and checks for messages from other power window motors prohibiting the window movement. If no prohibitive messages have been received, the BCM will send a serial data message to the passenger window motor or to the appropriate rear window switch which will perform the command as requested.
Conditions for Running the DTC
Battery voltage must be between 9-16 V.
Conditions for Setting the DTC
B316B 00
The BCM has detected the driver right front or left rear or right rear window switch is active for greater than 60 seconds.B316B 02
The BCM has detected the driver left front window switch is active for greater than 60 seconds.B317A 02
The BCM has detected the passenger window switch is active for greater than 60 seconds.B318A 02
The BCM has detected the left rear window switch is active for greater than 60 secondsB319A 02
The BCM has detected the right rear window switch is active for greater than 60 secondsB316B 39, B317A 39, B318A 39, B319A 39
The BCM has detected an internal failure within the affected door switchAction Taken When the DTC Sets
The affected power window will malfunction.
Conditions for Clearing the DTC
B316B 00, B316B 02, B317A 02, B318A 02, B319A 02
| • | The DTC will be current for as long as the fault is present. |
| • | The DTC will change from current to history when the fault is no longer present. |
| • | A history DTC will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present. |
B316B 39, B317A 39, B318A 39, B319A 39
If the DTC is current, the affected window switch must be replaced before the DTC can be cleared.Reference Information

Circuit/System Verification
| 1. | Ignition ON, command the command the M74D window motor - driver UP, DOWN, express UP and express DOWN by using the S79D window switch - driver. The M74D window motor - driver should perform the UP, DOWN, express UP and express DOWN commands. |
| ⇒ | If the M74d window motor - driver does perform as specified, refer to Driver Window Switch Malfunction. |
| 2. | Command the M74P window motor - passenger UP, DOWN, express UP and express DOWN by using the S79P window switch - passenger. The M74P window motor - passenger should perform the UP, DOWN, express UP and express DOWN commands |
| ⇒ | If the M74P window motor - passenger does perform as specified, refer to Passenger Window Malfunction. |
| 3. | Command the M74LR window motor - left rear to go UP and DOWN by using the S74LR rear window switch - left rear. The M74LR window motor - left rear should perform the UP and DOWN function . |
| ⇒ | If the M74LR window motor - left rear does perform as specified, refer to Left Rear Power Window Switch Malfunction. |
| 4. | Command the M74RR window motor - right rear UP and DOWN by using the S74RR rear window switch - right rear. The M74RR window motor - right rear should perform the UP and DOWN function. |
| ⇒ | If the M74RR window motor - right rear does perform as specified, refer to Right Rear Power Window Switch Malfunction. |
Circuit/System Testing
Driver Power Window Switch Malfunction
| 1. | Ignition OFF, disconnect the harness connector at the S79D window switch - driver. |
| 2. | Ignition ON, verify that the scan tool Driver Window Main Control Down Switch parameter is Inactive. |
| ⇒ | If not the specified value, test the control circuit terminal 3 for a short to ground. If the circuit tests normal, test or replace the M74D window motor - driver. |
| 3. | Verify that the scan tool Driver Window Main Control Up Switch parameter is Inactive. |
| ⇒ | If not the specified value, test the control circuit terminal 6 for a short to ground. If the circuit tests normal, test or replace the M74D window motor - driver. |
| 4. | Verify that the scan tool Driver Window Main Control Express Switch parameter is Inactive. |
| ⇒ | If not the specified value, test the control circuit terminal 2 for a short to ground. If the circuit tests normal, test or replace the M74D window motor - driver. |
| 5. | If all circuits test normal, test or replace the S79D window switch - driver. |
Passenger Window Malfunction
| 1. | Ignition OFF, disconnect the harness connector at the S79P window switch - passenger. |
| 2. | Ignition ON, verify that the scan tool Passenger Window Switch at Door parameter is Inactive. |
| ⇒ | If not the specified value, test the control circuit terminal listed below for a short to ground. If the circuit tests normal, test or replace the M74LR window motor - left rear. |
| • | Terminal 6 |
| • | Terminal 7 |
| • | Terminal 8 |
| 3. | If all circuits test normal, test or replace the S79P window switch - passenger. |
Left Rear Power Window Switch Malfunction
| 1. | Ignition OFF, disconnect the harness connector at the S79LR window switch - left rear. |
| 2. | Ignition ON, verify that the scan tool Left Rear Window Switch at Door parameter is Inactive. |
| ⇒ | If not the specified value, test the control circuit terminal listed below for a short to ground. If the circuit tests normal, test or replace the M74LR window motor - left rear. |
| • | Terminal 6 |
| • | Terminal 7 |
| • | Terminal 8 |
| 3. | If all circuits test normal, test or replace the S79LR window switch - left rear. |
Right Rear Power Window Switch Malfunction
| 1. | Ignition OFF, disconnect the harness connector at the S79RR window switch - right rear. |
| 2. | Ignition ON, verify that the scan tool Right Rear Window Switch at Door parameter is Inactive. |
| ⇒ | If not the specified value, test the control circuit terminal listed below for a short to ground. If the circuit tests normal, test or replace the M74RR window motor - right rear. |
| • | Terminal 6 |
| • | Terminal 7 |
| • | Terminal 8 |
| 3. | If all circuits test normal, test or replace the S79RR window switch - right rear. |
