Pinpoint Test A : B1182:00

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Make sure all aftermarket electronic equipment has been disconnected (if possible) and the customer has been questioned about the electronic equipment they may have been using in the vehicle when this concern was identified.

Normal Operation and Fault Conditions

REFER to: Tire Pressure Monitoring System (TPMS) - System Operation and Component Description .

The TPMS communication can be interrupted by RFI, which can cause intermittent issues that are not vehicle concerns. RFI is generated by electrical motors and appliance operation, cellular telephones, remote transmitters, power inverters and portable entertainment equipment.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
BCM B1182:00	Tire Pressure Monitoring System: No Sub Type Information	Set by the BCM in continuous memory when all 4 of the tire pressure sensors are faulted, not responding or when data is not received by the BCM.

Possible Sources

TPMS sensors not installed
RTM communication concern
TPMS sensors not trained
TPMS sensor
BCM

Visual Inspection and Pre-checks

Inspect for cell phone chargers or GPS units.
Inspect for non-Original Equipment Manufacturer (OEM) wheels or run-flat tires.
Verify horn operation.
Verify spare tire is not in use.

A1 CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Using a diagnostic scan tool, carry out the Network Test.
Does the BCM pass the Network Test?

Yes GO to A2

No DIAGNOSE the no communication with the BCM. REFER to: Communications Network .

A2 TRAIN THE TPMS (TIRE PRESSURE MONITORING SYSTEM) SENSORS

Train all 4 TPMS sensors. REFER to: Tire Pressure Monitoring System (TPMS) Sensor Location Calibration .

Did all of the TPMS sensors transmit correctly and did the horn sound when each sensor transmitted to the BCM?

Yes	The system is operating correctly at this time. The concern may have been caused by RFI. REFER to: Tire Pressure Monitoring System (TPMS) - System Operation and Component Description .

GO to A3

A3 REPEAT THE TPMS (TIRE PRESSURE MONITORING SYSTEM) TRAINING

NOTE: Make sure that all aftermarket electronic equipment has been disconnected (if possible) and the customer has been questioned about the types of electronic equipment they may have been using in the vehicle when this issue was identified.
- NOTE: A spare tire cannot be programmed to the vehicle, even if equipped with a TPMS sensor. If a damaged road wheel is located in the luggage compartment and the BCM cannot communicate with it, or if the damaged wheel has been dropped off at a dealership or repair shop, the BCM sets a TPMS sensor fault.
  
  If the spare tire is in use, repair and remount the road wheel as necessary to restore system operation. REFER to: Tire Pressure Monitoring System (TPMS) - System Operation and Component Description .
- Move the vehicle to rotate the wheels at least one-fourth of a turn. Leave the vehicle doors open. Start the sensor training procedure at a different wheel. REFER to: Tire Pressure Monitoring System (TPMS) Sensor Location Calibration .
Did any of the TPMS sensors train and did the horn sound when each sensor transmitted to the BCM?

Yes INSTALL a new TPMS sensor for each sensor that failed to train. REFER to: Tire Pressure Monitoring System (TPMS) Sensor .

No GO to A4

A4 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all BCM connectors.

Repair:
- corrosion (replace connector or terminals - clean module pins)
- damaged or bent pins - replace terminals/pins
- pushed-out pins - replace pins as necessary

Reconnect the BCM connectors. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes

The sensors may not be present. DISMOUNT all 4 tires and VERIFY the sensors are present and mounted to the wheels. REFER to: Wheel And Tire . If a sensor is missing, INSTALL a new sensor. REFER to: Tire Pressure Monitoring System (TPMS) Sensor . If all the sensors are present, CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB, GSB, SSM, or FSA. If a service article exists for the concern, DISCONTINUE this test and FOLLOW the service article instructions. If no Technical Service Bulletins (TSBs) address this concern, Refer to BCM Guided Routine Testing .

No	The system is operating correctly at this time. The concern may have been caused by RFI. REFER to: Tire Pressure Monitoring System (TPMS) - System Operation and Component Description .
