U1000:00 | 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, Click here to access Guided Routine (BCM). Internet Explorer version 11 or greater is required to perform this Pinpoint 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). |
