Pinpoint Test K: DTC B119D:17

Refer to Wiring Diagram Set 13, Power Distribution/SJB for schematic and connector information. Diagrams By Number

Normal Operation

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

- DTC B119D:17 (Vehicle Battery: Circuit Above Threshold) - This DTC sets in continuous memory if the SCCM detects battery voltage above 19 volts on the battery voltage supply circuit.

This pinpoint test is intended to diagnose the following:
- Charging system
- SCCM

NOTE: Carry out a thorough inspection and verification before proceeding with the pinpoint test. Refer to Inspection and Verification. Inspection and Verification

NOTE: DTC B119D:17 can set if the vehicle has been recently jump started or the vehicle battery has been recently charged.

PINPOINT TEST K: DTC B119D:17

NOTICE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.

-------------------------------------------------
K1 CHECK FOR HIGH BATTERY VOLTAGE AND/OR CHARGING SYSTEM DTC IN OTHER MODULES

- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - All CMDTCs.
- Retrieve and recorded all CMDTCs from all modules.
- Are any high battery voltage and/or charging system DTCs present in other modules?

Yes
REFER to Charging System Testing and Inspection to diagnose an overcharging condition.

No
GO to K2.

-------------------------------------------------
K2 CHECK THE BATTERY VOLTAGE

- Turn off all interior/exterior lights and accessories.
- 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?

Yes
REFER to Charging System Testing and Inspection to diagnose an overcharging condition.

No
GO to K3.

-------------------------------------------------
K3 RECHECK FOR SCCM DTC B119D:17

- Turn the engine off.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - SCCM.
- Clear the continuous memory DTCs and repeat the self-test.
- Is DTC B119D:17 present in the SCCM?

Yes
GO to K4.

No
The system is operating normally at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.

-------------------------------------------------
K4 CHECK FOR CORRECT SCCM OPERATION

- Ignition OFF.
- Disconnect: All SCCM Connectors.
- Check the SCCM connectors for:
- corrosion
- damaged pins
- pushed-out pins
- Connect: All SCCM Connectors.
- Make sure the SCCM connectors are seated correctly, then operate the system and verify the concern is still present.
- Is the concern still present?

Yes
INSTALL a new SCCM. REFER to Steering Column Control Module (SCCM) Service and Repair. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.

No
The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
