Solid State Driver Protection Active -Driver Disabled: No Sub Type Information
|
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.
ADDRESS all other Diagnostic Trouble Codes (DTCs) first. After the cause
of the concern is corrected, CLEAR the Diagnostic Trouble Codes (DTCs).
REPEAT the self-test. 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).
|
|
U3000:49
|
Control Module: Internal Electronic Failure
|
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. The cause of
the excessive current draw MUST be corrected before a new BCM
is installed. ADDRESS all other Diagnostic Trouble Codes (DTCs) first.
After the cause of the concern is corrected, INSTALL a new BCM .

-
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.

Normal Operation and Fault Conditions
REFER to: Exterior Lighting - System Operation and Component Description (417-01 Exterior Lighting, Description and Operation).
REFER to: Exterior Lighting - Overview (417-01 Exterior Lighting, Description and Operation).
Possible Sources
-
LH steering column multifunction switch
-
SCCM
-
BCM
Visual Inspection and Pre-checks
- Inspect the LH steering column multifunction switch for damage.
|
| E1 CHECK THE HIGH BEAM OPERATION |
-
Place the headlamp switch in the HEADLAMPS ON position.
-
Activate and deactivate the high beams using the high beam function of the LH steering column multifunction switch.
Do the high beams operate correctly?
| No |
If one or both high beams are inoperative, GO to Pinpoint Test B
If one or both high beams are always on, GO to Pinpoint Test D
|
|
| E2 CHECK THE LH (LEFT-HAND)
MULTIFUNCTION SWITCH INPUT |
-
Using a diagnostic scan tool, view SCCM Parameter Identifications (PIDs).
-
Monitor the SCCM Flash to Pass Switch (FLASH-to-PASS) PID while placing
the LH steering column multifunction switch in the FLASH-TO-PASS
position.
Does the PID value agree with the LH steering column multifunction switch position?
| No |
INSTALL a new LH steering column multifunction switch.
REFER to:
Steering Column Multifunction Switch LH (211-05 Steering Wheel and
Column Electrical Components, Removal and Installation).
TEST the system for normal operation. If the concern still exists, GO to E3
|
|
| E3 CHECK FOR CORRECT SCCM (STEERING COLUMN CONTROL MODULE)
OPERATION |
-
Disconnect and inspect all SCCM 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 SCCM and all related in-line connectors. Make sure they seat and latch correctly.
-

Overview
Multiplexing
is a method of sending 2 or more signals simultaneously over a single
circuit. Multiplexing allows 2 or more electronic modules (nodes) to
communicate over a twisted wire pair [data (+) and data (-)] network.
The information or messages that can be communicated on these wires
consists of commands, status or data. Multiplexing reduces the weight of
the vehicle by..
