And the year Corvette is....:huh:

All are history codes. You have no way of knowing when they happened. Could be best if you could clear them and then check to see if they re-appear


Possibly they could be:

U1160 Loss of Communications with LDCM

A0-LDCM - Left Door Control Module
B2282 Battery #1 Fault
B2284 Battery #2 Fault

A1-RDCM - Right Door Control Module
B2283 Battery #1 Fault
B2285 Battery #2 Fault

From reference material

"CIRCUIT DESCRIPTION
Each Door Control Module (LDCM and RDCM) has two main power feeds (high and low), and one main ground. The low power feed (battery 1) is used to provide power for each DCM logic and internal driver operation. The high power feed (battery 2) is used to provide power for systems that draw higher amounts of current (motors, lights etc.). For most functions, each DCM will operate properly when vehicle system voltage is between 9.0-16.0 volts . Each DCM also monitors the voltage level at battery 1 and battery 2 circuits and can determine if the voltage level received is out of range. If the voltage level is out of range in either circuit, then a malfunction is present and a DTC will set.

CONDITIONS FOR SETTING THE DTC
A DCM detects battery 1 voltage range under 8.5 volts or over 16.3 volts .
Condition must be present for 2 seconds .

ACTION TAKEN WHEN THE DTC SETS
Stores a history DTC B2282, B2283, B2284 or B2285 in a DCM memory.
These DTCs can only be set as a history code even if the malfunction is current.
No driver warning message will be displayed for this DTC."

 

It is an '01 model. Thank you for your replies

 

DTC's Door Control Modules

H = History:

U-1160 Loss of Communications with LDCM (Left Door Control Module)
B-2282 Battery #1 Fault DCM-LEFT
B-2283 Battery #1 Fault DCM-RIGHT
B-2284 Battery #2 Fault DCM-LEFT
B-2285 Battery #2 Fault DCM-RIGHT

With a fully charged battery, clear codes and if they reset:

Check I/P ELE Center Mini-fuse #33 (10a)
DCM/IPEC connectors/wiring for short or open to GND (voltage 10.0-14.0v)

Circuits:
LDCM CKT 2140 (0.35 ORN)/CKT 2640 (2 ORN)
RDCM CKT 2340 (0.35 ORN)/CKT 2240 (2 ORN)

If all checks out, replace DCM's.

The *********H************* shows that what ever was wrong and for what ever reason they cleared.
You can clear them out or leave them. If the check engine lite never came on and you never did a code check those codes could stay there for the life of the car. If the check engine lite don't come on don't knock yourself out trying to figure out what happened because you will never no..

 

Once again thanks everyone. artyon:
