Handles, Locks, Latches and Entry Systems
Pinpoint Test V: DTC B1317
Refer to Wiring Diagram Set 117, Remote Keyless Entry and Alarm for schematic and connector information. Diagrams By Number
Normal Operation
The Driver Door Module (DDM) monitors the voltage from the battery to determine if it goes above or below specific thresholds and sets DTC B1317 in continuous memory if the DDM detects high battery voltage above 15 volts on circuit 1213.
- DTC B1317 (Battery Voltage High) - a continuous memory DTC that sets when the DDM detects battery voltage above 15 volts on circuit 1213.
This pinpoint test is intended to diagnose the following:
- Charging system concern
- DDM
PINPOINT TEST V: DTC B1317
NOTE: DTC B1317 may be stored in the module memory due to previous battery charging or vehicle jump starting events.
-------------------------------------------------
V1 CHECK FOR DTC B1317, B1676 OR P0563 SET IN OTHER MODULES
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: (All Modules) Self-Test.
- Retrieve the continuous memory DTCs from all modules.
- Is DTC B1317, B1676 or P0563 (PCM) set in more than one module?
Yes
REFER to Charging System Testing and Inspection to diagnose an overcharging condition.
No
GO to V2.
-------------------------------------------------
V2 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 15 volts or higher?
Yes
REFER to Charging System Testing and Inspection to diagnose an overcharging condition.
No
GO to V3.
-------------------------------------------------
V3 RECHECK FOR DTC B1317
- Turn the engine off.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: DDM Self-Test.
- Clear the continuous memory DTCs.
- Carry out the DDM self-test.
- Is DTC B1317 present?
Yes
INSTALL a new DDM. REFER to Driver Door Module (DDM) Service and Repair. TEST the system for normal operation.
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.
