Diagnostic Overview

B11D9:17

Refer to Wiring Diagram Set 13 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) B11D9:17 can set if the vehicle has been recently jump started or the vehicle battery has been recently charged.

DTC Fault Trigger Conditions






Pinpoint Test

1. CHECK FOR HIGH BATTERY VOLTAGE AND/OR CHARGING SYSTEM DTC (Diagnostic Trouble Code) IN THE PCM (Powertrain Control Module)

1. Ignition ON.

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

3. Record all PCM (Powertrain Control Module) CMDTCs (Continuous Memory Diagnostic Trouble Codes).

Are any high battery voltage and/or charging system DTCs (Diagnostic Trouble Codes) present in the PCM (Powertrain Control Module)?








2. CHECK THE BATTERY VOLTAGE

1. Turn off all interior/exterior lights and accessories.

2. Start and run the engine at approximately 2,000 rpm for 3 minutes while monitoring the battery voltage.

Does the battery voltage rise to 16.5 volts or higher?








3. RECHECK FOR SCCM (Steering Column Control Module) DTC (Diagnostic Trouble Code) B119D:17

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

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

Is DTC (Diagnostic Trouble Code) B11D9:17 present in the SCCM (Steering Column Control Module)?








4. 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?
