| Circuit/System Description |
The body control module (BCM) supplies a pulse width modulated (PWM) voltage to the LED circuit of the power mode for backlight.
| Conditions for Running the DTC |
The ignition is ON.
| Conditions for Setting the DTC |
The BCM detects a short to voltage, short to ground, or an open in the PWM circuit for the power mode switch backlight LED circuit.
| Action Taken When the DTC Sets |
The BCM will not illuminate the LED backlighting supplied by the backlight lamp control circuit.
| Conditions for Clearing the DTC |
| • |
The condition responsible for setting the DTC no longer exists.
|
|
| • |
A history DTC will clear once 100 consecutive malfunction ignition cycles have occurred.

| Circuit/System Verification |
Open the drivers door and observe the power mode switch. The power mode switch backlight should be illuminated.
| Circuit/System Testing |
| 1. |
Disconnect the harness connector at the S38 Ignition Mode Switch.
|
|
| 2. |
Test for less than 5 Ω between the ground circuit terminal 4 and ground.
|
|
| 3. |
If greater than the specified range, test the ground circuit for an open/high resistance.
|
|
| 4. |
Connect a test lamp between the backlight control circuit of S38 Ignition Mode Switch terminal 8 and ground.
|
|
| 5. |
Close the driver's door and wait 30 seconds. Open the driver's door and check that the test lamp blinks.
|
|
| 6. |
If the test lamp does not flash, test the control circuit for an open circuit/high resistance or short to ground. If the circuit tests normal, replace the K9 Body Control Module.
|
|
| 7. |
If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the K9 Body Control Module.
|
|
| 8. |
If all circuits test normal, replace the S38 Ignition Mode Switch.
