Pinpoint Test H: DTC B1251:00

Normal Operation
- DTC B1251:00 (Tire Pressure Sensor Low Battery: No Sub Type Information) - This DTC sets in continuous memory in the Body Control Module (BCM) when there is a fault in the Tire Pressure Monitoring System (TPMS), such as a damaged or missing TPMS sensor(s), or when attempting to train a TPMS sensor(s) with a low battery. The TPMS warning indicator flashes for 70 seconds then illuminates continuously when the ignition switch is turned to the ON position. The message center also displays TIRE PRESSURE SENSOR FAULT.

This pinpoint test is intended to diagnose the following:

- TPMS sensor(s)

-------------------------------------------------
H1 TRAIN THE TPMS SENSORS TO DETERMINE THE INOPERATIVE SENSOR

- Train all 4 TPMS sensors. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training Tire Pressure Monitoring System (TPMS) Sensor Training.
- Did all of the TPMS sensors transmit correctly when each TPMS sensor transmitted to the TPM module?

Yes
CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.

No
If the TPMS sensors fail to train, REFER to Wheel Rotation And Sensor Training Techniques.

If the TPMS sensor(s) fails to train a second time, INSTALL a new TPMS sensor(s) for the sensor(s) in question. REFER to Tire Pressure Monitoring System (TPMS) Sensor Service and Repair.
