TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: C2171/71: Transmitter ID not Registered
DTC C2171/71 - Transmitter ID not Registered
DESCRIPTION
The IDs of each tire pressure warning valve and transmitter are registered in the tire pressure warning ECU.
When the ECU detects that any transmitter ID code is not registered in the ECU, the DTC will be output.
INSPECTION PROCEDURE
NOTICE:
- When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using the Techstream and write them down before removal.
- It is necessary to perform registration of the transmitter IDs into the tire pressure warning ECU if the ECU has been replaced. Programming and Relearning
PROCEDURE
1. CONFIRM REGISTRATION CONDITION (REGISTERED ID CODES)
(a) Turn the power switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the power switch on (IG) and turn the Techstream on.
(d) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(e) Check the values by referring to the table below.
Tire Pressure Monitor
OK:
The registered transmitter ID codes are displayed on the Techstream screen.
NG -- PERFORM REGISTRATION (TRANSMITTER ID)
OK -- REPLACE TIRE PRESSURE WARNING ECU
2. PERFORM REGISTRATION (TRANSMITTER ID)
(a) Register the transmitter IDs for all the wheels. Programming and Relearning
NEXT -- Continue to next step.
3. CONFIRM TIRE INFLATION PRESSURE (DATA LIST)
(a) Turn the power switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the power switch on (IG) and turn the Techstream on.
(d) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(e) Check the values by referring to the table below.
Tire Pressure Monitor
HINT:
- *: It may take about 2 or 3 minutes until the values are displayed.
- When no "ID Tire Inflation Pressure" data has changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270°. Then rapidly release the tire pressure and recheck the data.
Result
B -- REPLACE TIRE PRESSURE WARNING ECU
A -- END
