Pinpoint Test AG: DTC B1317
Refer to Wiring Diagram Set 60, Instrument Cluster for schematic and connector information. Diagrams By Number
- DTC B1317 (Battery Voltage High) - sets in continuous memory if the Instrument Cluster (IC) detects battery voltage above 18 volts on the on the B+ voltage input circuit.
This pinpoint test is intended to diagnose the following:
- Charging system concern
- IC
PINPOINT TEST AG: DTC B1317
NOTE: DTC B1317 may be stored in the module memory due to past battery charging or vehicle jump starting events.
-------------------------------------------------
AG1 CHECK FOR DTC B1317, B1676 OR P0563 SET IN OTHER MODULES
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: 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 AG2.
-------------------------------------------------
AG2 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 15.5 volts or higher?
Yes
REFER to Charging System Testing and Inspection to diagnose an overcharging condition.
No
GO to AG3.
-------------------------------------------------
AG3 RECHECK FOR DTC B1317
- Turn the engine off.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IC Self-Test.
- Clear the continuous memory DTCs.
- Carry out the IC self-test.
- Is DTC B1317 present?
Yes
INSTALL a new IC. REFER to Instrument Cluster (IC) 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.
