System Description EKS008NW Control of the parking, license plate, and tail lamp operation is dependent upon the position of the lighting switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body control module) receives input signal requesting the parking, license plate, and tail lamps to illuminate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. When energized, this relay directs power to the parking, license plate, and tail lamps, which then illuminate. Power is supplied at all times ? through 10A fuse (No. 41, located in the IPDM E/R) ? to tail lamp relay, located in the IPDM E/R, and ? through 50A fusible link (letter f , located in the fuse and fusible link box) ? to BCM terminal 70. With the ignition switch in the ON or START position, power is supplied ? through 10A fuse [No. 1, located in the fuse block (J/B)] ? to BCM terminal 38. With the ignition switch in the ACC or ON position, power is supplied ? through 10A fuse [No. 6, located in the fuse block (J/B)] ? to BCM terminal 11. Ground is supplied ? to BCM terminal 67 ? through grounds F14, M57 and M61.
You have battery voltage at the fuse , not current . You won';t have current flow until the light's work . The brake switch does not have the voltage value's you would think. An it's called a brake pedal position sensor , it is a low voltage sensor powered by the BCM - body control module .
Stop Lamps
The body control module (BCM) is responsible for controlling the stop lamps. When the driver presses the brake pedal, the BCM will receive a signal from the brake pedal position sensor. The BCM then supplies battery positive voltage to both left and right stop lamp assemblies and to the center high mounted stop lamp (CHMSL). The stop lamps are grounded at G401 and G403. The CHMSL is grounded at G302.
Your best bet , take it to a qualified repair shop before you short out the BCM.
You mite have a DTC - diagnostic trouble code stored in the BCM - body control module , The BCM controls the interior lights ! Have you heard of a BCM ?
DTC B2615
The body control module (BCM) receives a ground signal from the door jamb, liftglass/liftgate, or courtesy lamp switches requesting courtesy/dome lamp illumination. When this occurs, the BCM directly sends a voltage through the courtesy lamp supply voltage circuit illuminating the courtesy/dome lamps.
Conditions for Setting the DTC
?€¢
When the BCM receives a courtesy lamp illumination request signal and the courtesy lamp supply voltage circuit is shorted to ground.
?€¢
When the BCM is not receiving a courtesy lamp illumination request signal and the courtesy lamp supply voltage circuit is shorted to voltage or open only to the first splice from the BCM.
?€¢
There is a loss of the rear fuse block TBC 3 battery supply voltage to the BCM for more than 1 second
Diagnostic Aids
?€¢
Perform a visual inspection for loose or poor connections at all related components. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
?€¢
Only an open circuit up to the first splice from the BCM will set DTC B2615.
DTC B3801
The body control module (BCM) monitors the courtesy lamp switch signal circuit in order to determine when the courtesy/dome lamps should be illuminated. When the BCM senses that the courtesy lamp switch signal circuit is grounded when the switch is activated, the BCM will directly illuminate the courtesy/dome lamps. Do you know what a scan tool is ? not a code reader !
Courtesy Lamps Inoperative
sounds like your head light switch took a ......go to napa and buy another one and change it out if you can't do it yourself i live in chicagoland area good luck
Hi,
If that area is the only that does not lights up, that means the bulb is already busted and you have to replace it. The interior lighting system ( panel gauge lights, switch lights, dome lights, and anything that lights up inside ) is connected to that.
Fuse is located in the fuse box, 15 amps, "acc. light ".
Hope that helps you out!
