DTC Fault Trigger Conditions
DTC |
Description |
Fault Trigger Condition |
BCM B1445:11 |
Rear Park Lamps Output: Circuit Short To Ground |
A continuous memory and on-demand DTC that sets when the BCM detects a
short to ground from the license plate lamp output circuit.
|
BCM B1445:15 |
Rear Park Lamps Output: Circuit Short To Battery Or Open |
A continuous memory and on-demand DTC that sets when the BCM detects an
open or short to voltage from the license plate lamp output circuit.
|
BCM B1538:11 |
Left Rear Position Lamp Output: Circuit Short To Ground |
A continuous memory and on-demand DTC that sets when the BCM detects a
short to ground from the LH rear parking lamp output circuit.
|
BCM B1538:15 |
Left Rear Position Lamp Output: Circuit Short To Battery Or Open |
A continuous memory and on-demand DTC that sets when the BCM detects an
open or short to voltage from the LH rear parking lamp output circuit.
|
BCM B1539:11 |
Right Rear Position Lamp Output: Circuit Short To Ground |
A continuous memory and on-demand DTC that sets when the BCM detects a
short to ground from the RH rear parking lamp output circuit.
|
BCM B1539:15 |
Right Rear Position Lamp Output: Circuit Short To Battery Or Open |
A continuous memory and on-demand DTC that sets when the BCM detects an
open or short to voltage from the RH rear parking lamp output circuit.
|
BCM U1000:00 |
Solid State Driver Protection Active -Driver Disabled: No Sub Type Information |
This DTC sets when the BCM
has temporarily shut down the output driver. The module has
temporarily disabled an output because an excessive current draw exists
(such as a short to ground). The BCM
cannot enable the output until the cause of the short is corrected,
the Diagnostic Trouble Codes (DTCs) have been cleared and a successful
self-test is run. For additional information on BCM Field Effect Transistor (FET) protection, REFER
to: Module Controlled Functions - System Operation and Component
Description (419-10 Multifunction Electronic Modules, Description and
Operation).
|
BCM U3000:49 |
Control Module: Internal Electronic Failure |
This DTC sets when the BCM
has permanently shut down the output driver. The module has
permanently disabled an output because an excessive current draw fault
(such as a short to ground) has exceeded the limits that the BCM can
withstand. CORRECT the cause of the excessive current draw before
installing a new BCM . For additional information on BCM Field Effect
Transistor (FET) protection, REFER to: Module Controlled Functions -
System Operation and Component Description (419-10 Multifunction
Electronic Modules, Description and Operation).

B12 CHECK FOR CORRECT BCM (BODY CONTROL MODULE)
OPERATION |
-
Disconnect and inspect all BCM and all related in-line connectors.
-
Repair:
-
corrosion (install new connector or terminals – clean module pins)
-
damaged or bent pins – install new terminals/pins
-
pushed-out pins – install new pins as necessary
-
Reconnect the BCM and all related in-line connectors. Make sure they seat and latch correctly.
-
Operate the system and determine if the concern is still present.
Is the concern still present?
Yes |
CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a
TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB
instructions. If no Technical Service Bulletins (TSBs) address this
concern, INSTALL a new BCM . REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).
|
No |
The system is operating correctly at this time. The
concern may have been caused by module connections. ADDRESS the root
cause of any connector or pin issues.
