Normal Operation
- DTC B1317 (Battery Voltage High) - a continuous memory and on-demand DTC that sets in the Instrument Cluster (IC) if the IC detects battery voltage above 16 volts on the B+ keep alive voltage input circuit SBP07 (WH/RD).

This pinpoint test is intended to diagnose the following:

- Charging system concern
- IC



PINPOINT TEST AA: DTC B1317

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

-------------------------------------------------
AA1 CHECK FOR DTC B1317, B1676 OR P0536 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 P0536 (PCM) set in more than one module?

Yes
REFER to Charging System to diagnose an overcharging condition.

No
GO to AA2.

-------------------------------------------------
AA2 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 to diagnose an overcharging condition.

No
GO to AA3.

-------------------------------------------------
AA3 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) Instrument Cluster (IC). TEST the system for normal operation.

No
The system is operating correctly at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle.
