NOTICE:
Engine learned values cannot be reset by disconnecting the battery negative (-) terminal or removing the EFI NO. 1 and ETCS fuses.
HINT:
If a message indicating learned value initialization failure is displayed on the screen, confirm the execution conditions, and perform learned value initialization again.
If 0 is displayed for all the air fuel ratio learned values, initialization has completed correctly.
If a value other than 0 is displayed for one of the air fuel ratio learned values, perform initialization again. After initialization, confirm the air fuel ratio learned values. If a value other than 0 is displayed, replace the ECM.
HINT:
Learning starts when the engine coolant temperature is 80°C (176°F) or higher.
Standard:
Engine Idle Speed |

600 to 700 rpm |
HINT:
After that, check the idle speed. If the value is out of the specified range, perform the procedure below.
CAUTION:
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
HINT:
History information for driving and stopping is necessary to update idle learning.
Standard:

Vehicle Speed or Engine Speed Signal Malfunction (C2173/73)
DESCRIPTION
The tire pressure warning ECU receives a vehicle speed signal from the combination
meter and an engine speed signal from the ECM. The tire pressure warning ECU uses
these signals to detect DTCs C2121/21 to C2124/24 (No Signal from Transmitter) ...
