Engine Codes

[Number1olddog]

My check engine light came on in my 21 JLURD and luckily I have a tazer to read them. Unfortunately google is not shedding any light on what the actual problem is. Can anyone tell me what these are?

P163A-15
P163E-15
B16E7-15
There was a "body control module" on the cluster that came up on my screen before the codes came up, any help would be appreciated.

B16E7-15 Body Control Module (BSM) - License Plate Lamp Control - Circuit Short to Battery or Open

Are you sure the others are right? There’s a P1634 that’s TCM related.

Code: B16E7-15

Definition: License Plate Lamp Control - Circuit Short To Battery Or Open

Description: When the Body Control Module (BCM) receives an input from the headlamp switch, requesting park lamp illumination, the BCM provides a Pulse Width Modulated (PWM) voltage output to the License Plate Lamp. A ground path for the License Plate Lamp is present through the harness.

Cause:

• LICENSE PLATE LAMP DRIVER CIRCUIT OPEN
• LICENSE PLATE LAMP DRIVER CIRCUIT SHORTED TO VOLTAGE
• GROUND CIRCUIT OPEN
• LICENSE PLATE LAMP BULB
• BODY CONTROL MODULE (BCM)

Failure Type:Circuit Short To Battery or OpenThis sub type is used for failures, where the condition detected by the control module is the same for either indicated failure mode.

should the other ones start with "B"?

Code: B163E-15

Definition: Front Right Turn Lamp Control - Circuit Short To Battery Or Open - Base

Description: The Body Control Module (BCM) receives CAN Bus messages from the Steering Column Control Module (SCCM), requesting Left or Right Turn Lamp illumination. When the BCM receives this CAN Bus message, the BCM provides a Pulse Width Modulated (PWM) output through the Front Turn Signal Control circuit to the Left or Right Front Turn Lamp. A ground path for the Left and Right Front Lamp Assemblies is provided through the wiring harness to the body sheet metal.

Cause:

• RIGHT FRONT TURN LAMP DRIVER CIRCUIT OPEN
• RIGHT FRONT TURN LAMP DRIVER CIRCUIT SHORTED TO VOLTAGE
• GROUND CIRCUIT OPEN
• TURN SIGNAL BULB
• BODY CONTROL MODULE (BCM)

Failure Type:Circuit Short To Battery or OpenThis sub type is used for failures, where the condition detected by the control module is the same for either indicated failure mode.

Code: B163A-15

Definition: Front Left Turn Lamp Control - Circuit Short To Battery Or Open - Base

Description: The Body Control Module (BCM) receives CAN Bus messages from the Steering Column Control Module (SCCM), requesting Left or Right Turn Lamp illumination. When the BCM receives this CAN Bus message, the BCM provides a Pulse Width Modulated (PWM) output through the Front Turn Signal Control circuit to the Left or Right Front Turn Lamp. A ground path for the Left and Right Front Lamp Assemblies is provided through the wiring harness to the body sheet metal.

Cause:

• LEFT FRONT TURN LAMP DRIVER CIRCUIT OPEN
• LEFT FRONT TURN LAMP DRIVER CIRCUIT SHORTED TO VOLTAGE
• GROUND CIRCUIT OPEN
• LEFT FRONT TURN SIGNAL BULB
• BODY CONTROL MODULE (BCM)

Failure Type:Circuit Short To Battery or OpenThis sub type is used for failures, where the condition detected by the control module is the same for either indicated failure mode.

a little backstory. I did have a body control module replaced about 9 months ago. My aux battery was holding a charge but wouldn't work at a stop (always stated, stop start not available battery charging). Not a big deal, just wanted it fixed. I do have a fab fours rear tire carrier and have not put a license plate light on it as of yet but doesn't make since why it's just now popping up. Wasn't worried about the other codes but all that popped up are:
B16E7-15
P163A-15
P163E-15
B16DF-15
C16D7-15
I also have kbd front fenders with turn signals / Motobuilt rear tailights and morimoto front led headlights. I have changed all lights from halogen to LED with the tazer but all this is now showing up and I am going on a Jeep trip Thursday for 4 days. Gotta love it.
