Invalid Data Received From Body Control Module: Event Information
|
This DTC sets when data is invalid from the BCM . CLEAR the DTC .
REPEAT the self-test. If DTC U0422:68 returns, RETRIEVE and REPAIR all
Diagnostic Trouble Codes (DTCs) set in the BCM .
REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Diagnosis and Testing).
|
|
U1000:00
|
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 TRM
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.
|
|
U2100:00
|
Initial Configuration Not Complete: No Sub Type Information
|
CHECK the vehicle service history for recent service actions related to
this module. This DTC sets due to incomplete or incorrect PMI
procedures. If there have been recent service actions with this module,
REPEAT the PMI procedure as directed by the diagnostic scan tool.
REFER
to: Module Configuration - System Operation and Component Description
(418-01 Module Configuration, Description and Operation).
If there have been no recent service actions, INSTALL a new TRM to correct the failure to retain configuration data.
|
|
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 TRM can withstand. The cause of
the excessive current draw MUST be corrected before a new TRM
is installed. ADDRESS all other Diagnostic Trouble Codes (DTCs) first.
After the cause of the concern is corrected, INSTALL a new TRM .
