Tire Pressure Monitoring (from 12/2010)

TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: C2171/71: Transmitter ID not Registered
C2171/71 - Transmitter ID not Registered

DESCRIPTION

The IDs of each tire pressure warning valve and transmitters are registered to the tire pressure warning ECU. When the ECU detects that transmitter ID is not registered in the ECU, a DTC is output.





INSPECTION PROCEDURE

NOTICE:
* When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using the Techstream and note them down before removal.
* It is necessary to perform the initialization Initialization (from 12/2010) after the registration Registration (from 12/2010) of the transmitter IDs into the tire pressure warning ECU if the ECU has been replaced.

PROCEDURE

1. CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES)

(a) Set the air pressure of all the wheels to the specified value Precaution (from 12/2010).

(b) Make sure that the ignition switch is off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch on (IG).

(e) Turn the Techstream on.

(f) Check the values by referring to the table below. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

Tire Pressure Monitor:





HINT
*1: Displayed only when the ID No. is not registered.

(g) Check the ID No. on the identified transmitter by removing it from the tire and wheel.

OK:

The registered transmitter ID codes are displayed on the Techstream display.

NG -- PERFORM REGISTRATION (TRANSMITTER ID)

OK -- REPLACE TIRE PRESSURE WARNING ECU Removal (from 12/2010)

2. PERFORM REGISTRATION (TRANSMITTER ID)

(a) Register the transmitter IDs for all the wheels Registration (from 12/2010).

NEXT -- Continue to next step.

3. READ VALUE USING TECHSTREAM (TIRE INFLATION PRESSURE)

(a) Set the air pressure of all the wheels to the specified value Precaution (from 12/2010).

(b) Make sure that the ignition switch is off.

(c) Connect the Techstream to the DLC3.

(d) Turn the ignition switch on (IG).

(e) Turn the Techstream on.

(f) Check the values by referring to the table below. Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

Tire Pressure Monitor:





HINT
*1: It may take about 2 or 3 minutes until the values are displayed. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2125/25 Tire Pressure Monitoring (from 12/2010).

Result:





B -- REPLACE TIRE PRESSURE WARNING ECU Removal (from 12/2010)

A -- END
