Tire Pressure Monitoring System

Pinpoint Tests

Pinpoint Test E: DTC B1317

Normal Operation

The Tire Pressure Monitoring System (TPMS) monitors the voltage from the battery to determine if it goes above or below specific thresholds. DTC B1317 sets in continuous memory if the TPMS detects high battery voltage above 16 volts.

- DTC B1317 (Battery Voltage High) - sets if the voltage supplied to the TPM/Vehicle Security Module (VSM) exceeds 16 volts during the TPM/ VSM self-test or normal operation, with vehicle speed greater than 5 km/h (3 mph).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Charging system concern
- TPM/VSM


PINPOINT TEST E: DTC B1317

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

-------------------------------------------------
E1 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 E2.

-------------------------------------------------
E2 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 E3.

-------------------------------------------------
E3 RECHECK FOR DTC B1317


- Turn the engine off.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: TPM/ VSM Self-Test.
- Clear the continuous memory DTCs.
- Carry out the IC self-test.
- Is DTC B1317 present?

Yes
INSTALL a new TPM/VSM. REFER to Tire Pressure Monitoring System (TPMS) Module 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.
