Pinpoint Test AN: DTC B1317

Refer to Wiring Diagram Set 60, Instrument Cluster for schematic and connector information. Diagrams By Number

Normal Operation
- DTC B1317 (Battery Voltage High) - a continuous memory DTC that sets if the IC detects battery voltage above 16 volts on the B+ keep alive circuit.

This pinpoint test is intended to diagnose the following:

- Charging system concern
- IC

PINPOINT TEST AN: DTC B1317

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

NOTE: DTC B1317 may be stored in the module memory due to past battery charging or vehicle jump starting events.

-------------------------------------------------
AN1 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 AN2.

-------------------------------------------------
AN2 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 AN3.

-------------------------------------------------
AN3 RECHECK FOR DTC B1317


- Turn the engine off.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: 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) Instrument Cluster (IC). 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.
