Solid State Driver Protection Actived -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,

Reverse Lamp: Circuit Short To Ground
|
A continuous memory and on-demand DTC that sets when the BCM detects a short to ground from the reverse lamps output circuit.
|
B1277:15
|
Reverse Lamp: Circuit Short To Battery or Open

|
Solid State Driver Protection Actived -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).
|
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).
