More Codes what dose it mean

[RunningBull]

Is this
C=121A
U=0100,0101,0121
B1608/B1BBC/B212D/B1BB8,B223D,B212C/B1A12

[Super T]

That's a lotta codes! No clue, hopefully someone does.

[JonW]

C121A = Steering angle sensor not initialized
U0100 = Lost communication with ECM/PCM
U0101 = Lost communication with TCM
U0121 = Lost communication with ABS
B1608 = Headlamp input circuit high
B1BBC = OCS negative system weight
B212D = Ignition run only input circuit open
B1BB8 = SRS warning indicator status mismatch
B223D = Occupant classification module DTC present
B212C = Ignition run/start input circuit open
B1A12 = (unknown) probably related to key or SKREEM error though

If I had to make a guess, I would say one of the 3 things happened:
1. You had flash downloads applied to your vehicle. Many erroneous DTC codes are generated during flashing and should be cleared after flashing
2. You disconnected/reconnected computers in the car with the power still applied
3. An interruption (break or short) in the CAN network caused communication errors.

well it's kind of wierd since none have taking
place Im thinking the remote start has somthing to do with it
not shure how but ever since the first one went wacky
and replaced it with a new one it's been doing this.
I think im going to invest in OBII scanner so I can
erase the codes my self untill we find what is going on here

[Super T]

Remote start shouldn't interfere w/ any of those circuits though. Is it the Mopar unit?

[RunningBull]

no it's not

[Bubba's Dragon]

Can anyone help with the B1BBC = OCS negative system weight?

[Magnum375 Jr]

Did you pull your cables off your battery?

B1BBC-OCS NEGATIVE SYSTEM WEIGHT

• When Monitored:

• While the CAN bus ignition status is in IGN_RUN, the module checks the sensor input ranges.
• Set Condition:</B> If the module detects a seat weight sensor input with the total seat weight below -6.5 kg +/- 1kg.

Possible Causes DAMAGE TO THE PASSENGER SEAT STRUCTURE, RISER ASSEMBLY, CROSSMEMBERS, SEAT TRACKS, FLOOR PAN OBJECT UNDER SEAT OR REAR SEAT FOLDED DOWN AND RESTING AGAINST PASSENGER SEAT OCCUPANT CLASSIFICATION MODULE (OCM)
</B>
Diagnostic Test

1. TEST CONDITIONS </B>

• ACTIVE INTERNAL DTC
• IGNITION DTC
• BATTERY DTC
• SEAT WEIGHT SENSOR DTC

NOTE: Ensure the battery is fully charged.
NOTE: When reconnecting Airbag system components, the ignition must be turned off and the battery must be disconnected.
Turn the ignition on, then off, and then on again.
With the scan tool, read Occupant Classification Module (OCM) DTCs.

Does the scan tool display any active DTCs listed above?
Yes

• Diagnose and repair the DTCs. Refer to the Table of Contents in this Section for a complete list of symptoms.

No

• Go To 2

2. ACTIVE OR STORED DTC </B>

With the scan tool, read OCM DTCs.

Does the scan tool display active: B1BBC-NEGATIVE SYSTEM WEIGHT?
Yes

• Go To 3

No

• Go To 4

3. PERFORM OCCUPANT CLASSIFICATION MODULE SYSTEM VERIFICATION TEST </B>

Verify that the passenger seat is empty.
Perform a visual inspection of the Passenger Seat, wiring, connectors, risers, sensors, and retainers. Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals. Also, inspect for damaged or bent risers, a damaged or bent seat and seat structure, damaged or bent seat tracks, and damaged or loose sensors. Repair or replace any problems found in accordance with the service information and then continue this procedure. Refer to 23 - BODY/SEATS.

NOTE: Failure to follow the test instructions or aborting the test will cause faults to set when performing the Occupant Classification Module System Verification Test. To prevent faults due to process errors: Verify That All Tests Steps That Led You Here Were Performed As Directed; Verify That The Ignition Is In Run; Wait 30 Seconds After Changing The Seat Weight Before Proceeding To Allow The System To Stabilize; Only Press Scan Tool Buttons When Directed To Do So; and Perform The Occupant Classification Module System Verification Test To Completion.

With the scan tool in OCM, select More Options, select System Tests, and select Occupant Classification Module System Verification Test. Run the test by following the instructions displayed on the scan tool. When the test is complete, proceed as follows.
With the scan tool, read OCM DTCs.

Does the scan tool display active: B1BBC-OCS NEGATIVE SYSTEM WEIGHT DTC?
Yes

• Perform the *Diagnosis/Checkout Procedure For Seat Weight Sensors.
• Perform OCS VERIFICATION TEST - VER 1.

No - But Other DTCs Present

• Diagnose and repair the DTCs. Refer to the Table of Contents in this Section for a complete list of symptoms.

No - No Active DTCs Present

• Perform OCS VERIFICATION TEST - VER 1.

4. STORED B1BBC-OCS NEGATIVE SYSTEM WEIGHT DTC </B>

With the scan tool, record and erase all DTC's from all Airbag System Modules.
If any ACTIVE codes are present they must be resolved before diagnosing any stored codes.

WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Look for chafed, pierced, pinched, or partially broken wires and broken, bent, pushed out, spread, corroded, or contaminated terminals.
The following additional checks may assist you in identifying a possible intermittent problem.
Reconnect any disconnected components and harness connector.

WARNING: To avoid personal injury or death, turn the ignition on, then reconnect the battery.

With the scan tool monitor active codes as you work through the following steps.
Wiggle the wiring harness and connectors of the related airbag circuit or component.
If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop to stop.
IF only stored codes return continue the test until the problem area has been isolated.
In the previous steps you have attempted to recreate the conditions responsible for setting active DTC in question.

Are any ACTIVE DTC's present?
Yes

• Select appropriate symptom from Symptom List.

No

• No problem found at this time. Erase all codes before returning vehicle to customer.
