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 and sets DTC B1317 in continuous memory if the TPMS detects high battery voltage above 15 volts.
- DTC B1317 (Battery Voltage High) - If the voltage supplied to the TPMS/Vehicle Security Module (VSM) exceeds 16 volts during the TPMS/VSM self-test or normal operation, with vehicle speed greater than 5 km/h (3 mph), DTC B1317 will be set.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Charging system concern
- TPMS/VSM
PINPOINT TEST E: DTC B1317
NOTE: DTC B1317 can be set if the vehicle has been recently jump started, the battery has been recently charged or the battery has been discharged. The battery may become discharged due to excessive load(s) on the charging system from aftermarket accessories or if the battery has been left unattended with the accessories on
NOTE: Carry out a thorough inspection and verification before proceeding with the pinpoint test. Refer to Inspection and Verification. Inspection and Verification

E1 RETRIEVE ALL CMDTCs IN ALL MODULES
- Connect the scan tool.
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Self Test - TPMS/VSM.
- Is DTC B1317 present?
Yes
REFER to Charging System to diagnose the charging system. CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs). TEST the system for normal operation.
No
GO to E2.
-------------------------------------------------
E2 CHECK BATTERY CONDITION
- Ignition OFF.
- Refer to Battery and carry out the battery condition test. Pinpoint Tests
- Does the battery pass the condition test?
Yes
If the battery passed the condition test but required a recharge, REFER to Charging System. CLEAR all CMDTCs. TEST the system for normal operation. If the battery passed the condition test and did not require a recharge, GO to E3.
No
INSTALL a new battery. CLEAR all CMDTCs. TEST the system for normal operation.
-------------------------------------------------
E3 CHECK THE CHARGING SYSTEM VOLTAGE
NOTE: Do not allow the engine rpm to increase above 2,000 rpm while performing this step or the generator may self excite and result in default charging system output voltage. If engine rpm has gone above 2,000 rpm, shut the vehicle OFF and restart the engine before performing this step.
- Start the engine.
- Measure the voltage of the battery:
- Turn off all accessories and run the engine at 1,500 rpm for a minimum of 2 minutes.
- Is the battery voltage between 13-15.2 volts?
Yes
INSTALL a new TPMS/VSM. REFER to Tire Pressure Monitoring System (TPMS) Module Service and Repair.
No
REFER to Charging System to diagnose battery and charging system. TEST the system for normal operation.
