SUBJECT:

Tire Pressure Monitoring System (TPMS) Lamp Illuminated With Tires Inflated To Correct Pressure

 

OVERVIEW:

This bulletin involves using the wiTECH diagnostic tool to update the tire pressure values set in the TPMS control unit.

 

MODELS:

2015 (4C) Alfa Romeo 4C

NOTE: This bulletin applies to vehicles built on or after July 09, 2014 (MDH 0709XX) and on or before February 20, 2015 (MDH 0220XX).

 

SYMPTOM/CONDITION:

Front tires nominal pressure values are not correctly set in the TPMS control unit.

The customer may describe the TPMS telltale light on the instrument panel is flashing and/or illuminated, even if the tires are properly inflated.

 

DIAGNOSIS:

If a customer’s VIN is listed in VIP or your RRT VIN list, perform the repair. For all other customers that describe the symptom/condition listed above, perform the Repair Procedure.

Confirm that the correct wheels and tires are installed on the vehicle and that the tires are inflated to the recommended pressure indicated on the vehicle placard or tire inflation pressure label.

Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in

TechCONNECT, verify that no DTCs are set. If DTCs or symptom conditions, other than the one listed above are present, record the issues on the repair order and repair as necessary before proceeding further with this bulletin.

If the customer describes the symptom/condition listed above, perform the Repair Procedure.

 

REPAIR PROCEDURE:

NOTE: Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the TPMS pressure value update process.

Using the wiTECH diagnostic tool, updated to the latest software release, follow the repair process steps below to update the pressure values set in the TPMS control unit, setting the following values:

  • Front axle nominal tire pressure setting = 1800 mBar (26 psi).
  • Rear axle nominal tire pressure setting = 2000 mBar (29 psi).

NOTE: If the updating process is interrupted/aborted, it must be restarted.
