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 . REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation). 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
