Diagnostic Overview

B11D9:16

Refer to Wiring Diagram Set 42 for schematic and connector information Electrical Diagrams.

Normal Operation and Fault Conditions

The SCCM (Steering Column Control Module) continuously monitors input voltage for correct operation. If voltage outside of defined limits is detected by the SCCM (Steering Column Control Module), the applicable DTC (Diagnostic Trouble Code) sets.

DTC (Diagnostic Trouble Code) B11D9:16 can set if the vehicle battery has been discharged. The vehicle battery may become discharged due to excessive load(s) on the charging system from aftermarket accessories or if the vehicle has been left unattended with the accessories on.

DTC Fault Trigger Conditions






Visual Inspection and Diagnostic Pre-checks

- Make sure the vehicle battery terminals and cables are free of any corrosion and other contaminates.

- Make sure the vehicle battery terminals are tightened to their correct torque specifications.

Pinpoint Test

1. CHECK FOR SCCM (Steering Column Control Module) DTCs (Diagnostic Trouble Codes)

1. Ignition ON.

2. Using a scan tool, perform SCCM (Steering Column Control Module) self-test.

3. Clear the SCCM (Steering Column Control Module) DTCs (Diagnostic Trouble Codes) and repeat the self-test.

Is DTC (Diagnostic Trouble Code) B119D:16 still present?








2. CHECK FOR CHARGING SYSTEM DTCs (Diagnostic Trouble Codes) IN THE PCM (Powertrain Control Module)

1. Using a scan tool, perform PCM (Powertrain Control Module) self-test.

2. Record all CMDTCs (Continuous Memory Diagnostic Trouble Codes) from the PCM (Powertrain Control Module).

Are any charging system DTCs (Diagnostic Trouble Codes) present in the PCM (Powertrain Control Module)?








3. CHECK THE BATTERY CONDITION AND STATE OF CHARGE

1. Ignition OFF.

2. Carry out the Battery Condition Test. REFER to Diagnostic Routine A: Battery Condition Test Pinpoint Tests.

Is the battery OK?








4. CHECK THE SCCM (Steering Column Control Module) VOLTAGE SUPPLY

1. Measure and record battery voltage.

2. Disconnect: SCCM (Steering Column Control Module) C2414A.

3. Disconnect: SCCM (Steering Column Control Module) C2414B.

4. Measure:





5. Measure:









Are the voltages within 0.2 volt of the recorded battery voltage?








5. CHECK THE SCCM (Steering Column Control Module) GROUND CIRCUIT

1. Disconnect the battery negative cable. REFER to Battery Disconnect .

2. Measure:





3. Measure:








Are the resistances less than 3 ohms?








6. CHECK FOR CORRECT SCCM (Steering Column Control Module) OPERATION

1. Disconnect and inspect all SCCM (Steering Column Control Module) connectors.

2. Repair:

- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

3. Reconnect the SCCM (Steering Column Control Module) connectors and all previously disconnected exterior system connectors. Make sure they seat and latch correctly.

4. Operate the system and determine if the concern is still present.

Is the concern still present?
