Pinpoint Test F: Missing, Incompatible Or Defective Running Tire Low Pressure Sensor Or Receiver

1. Establish that a full size running wheel and tire assembly has a tire low pressure sensor installed. As a visual confirmation, a tire low pressure sensor has a metal valve stem rather than a rubber one and cannot be installed to a mini/space saver spare wheel.

Is a full size wheel and tire assembly with tire low pressure sensor installed?

• Yes: GO to  F2.
• No  : Install the correct wheel and tire assembly or tire low pressure sensor, of correct frequency, in accordance with that defined in the manufacturer approved diagnostic system new tire low pressure sensor application.

1. Remove the Tire Pressure Monitoring System power supply fuse and re-install it. Clear DTCs and leave the vehicle stationary for 15 minutes, then drive it at a speed greater than 15.5 mph (25 kph) continuously for at least 10 minutes.
   NOTE: If the vehicle speed drops below this value, the drive time to complete the test will need to be increased.

   The use of the manufacturer approved diagnostic system, and the datalogger signal 'Tire pressure monitor system status - learn mode status' will verify the completion of the test when the value returns to 'Inactive'.

2. Check for additional DTCs C1A5631, C1A5831, C1A6031, C1A6231, with identical time stamps.

Have all four DTCs logged with identical time stamps in the tire pressure monitoring system module?

• Yes  : Replace the tire pressure monitoring system radio frequency receiver.

  Refer to: Tire Pressure Monitoring System Receiver .

• No: GO to  F3.

1. Check tire pressure monitoring system DTCs.

Are any C1AXX31 DTCs logged?

• Yes  : Install the correct tire low pressure sensor, of correct frequency, in accordance with that defined in the manufacturer approved diagnostic system new tire low pressure sensor application, to the position identified by the logged DTC.

  Refer to: Tire Low Pressure Sensor .

• No  : No further action is required.
  NOTE: The use of the manufacturer approved diagnostic system, and the datalogger signal 'Tire pressure monitor system status - learn completed successfully' will verify the successful completion of the test.
