TIRE PRESSURE MONITORING: TIRE PRESSURE WARNING SYSTEM: C2171; Transmitter ID not Registered; 2013 MY FR-S [03/2012 -]
C2171 - Transmitter ID not Registered

DESCRIPTION

The IDs of each tire pressure warning valve and transmitter are registered to the door control receiver.

When the ECU detects that a transmitter ID code is not registered in the ECU, a DTC is stored.





INSPECTION PROCEDURE

NOTICE:
* When replacing the door control receiver, read the IDs stored in the old ECU using the Techstream and write them down before removal.
* It is necessary to perform registration Programming and Relearning of the transmitter IDs into the tire pressure warning ECU after the ECU has been replaced.
* When replacing the door control receiver on vehicles, be sure to perform Registration of Recognition Code to register the transmitter IDs after ECU replacement Registration.

PROCEDURE

1. CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES)

(a) Turn the ignition switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the ignition switch to ON.

(d) Turn the Techstream on.

(e) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
