INITIALIZATION
Procedures necessary when battery terminal is disconnected / reconnected
NOTE: After the engine switch is turned off, the HDD navigation system requires approximately 6 minutes to record various types of memory and settings. As a result, after turning the engine switch off, wait 6 minutes or more before disconnecting the cable from the negative (-) battery terminal.
Procedures necessary when ECU or other parts are replaced
1. PERFORM ROAD TEST TO ALLOW TCM TO LEARN
CAUTION:
- Perform the following procedures while strictly observing all traffic laws and speed limits.
- Do not accelerate or decelerate rapidly.
(a) "Road test" procedure is as follows:
(1) Warm up the engine.
(2) According to the replacement parts, perform the road test shown below.
HINT:
- *1: After gradually accelerating a distance of approximately 130 m (426.4 ft.) for a period of approximately 15 seconds, gradually decelerate a distance of approximately 45 m (147.6 ft.) for a period of approximately 5 seconds.
- *2: After gradually accelerating a distance of approximately 40 m (131.2 ft.) for a period of approximately 8 seconds, gradually decelerate a distance of approximately 20 m (65.6 ft.) for a period of approximately 4 seconds.

(3) Repeat until the shift shock and engine speed overrun settles down.
NOTE: Before repeating tests, stop the vehicle once, and then start moving the vehicle again.
2. RESET MEMORY
NOTICE:
- Perform the RESET MEMORY (AT initialization) when replacing the engine assembly or ECM.

6. DESCRIPTION OF CODE REGISTRATION
It is necessary to register the transmitter ID in the tire pressure warning ECU when replacing the tire pressure warning valve and transmitter and/or tire pressure warning ECU.
Prepare all transmitter ID data before starting registration.
(a) Before registration
(1) In case of tire pressure warning ECU replacement.
- Read the registered transmitter IDs that are stored in the old ECU using the Techstream and note them down.
- If reading stored transmitter IDs is impossible due to malfunctions of components such as the tire pressure warning antenna and receiver, remove the tires from the wheels and check the IDs located on the tire pressure warning valves and transmitters.
(2) In case of tire pressure warning valve and transmitter replacement.
- Take a note of the 7 digit number (transmitter ID) written on the tire pressure warning valve and transmitter.
NOTE: The transmitter ID is written on the tire pressure warning valve and transmitter. It will be unable to be read after installing the tire pressure warning valve and transmitter on the tire and wheel. Therefore, take a note of the transmitter ID before installing the tire pressure warning valve and transmitter.
7. REGISTER TRANSMITTER ID
(a) Set the air pressure of all wheels to the specified value.
(b) Turn the engine switch OFF.
(c) Connect the Techstream to the DLC3.
(d) Turn the engine switch ON (IG) and the tester ON.
(e) Enter the menu items in this order: Chassis / Tire Pressure Monitor / Utility / ID Registration /
(f) Perform the procedures displayed on the Techstream.

(i) Confirmation of transmitter ID registration.
(1) Enter the menu items in this order: DIAGNOSIS / OBD/MOBD / CHASSIS / TIRE PRESSURE / DATA LIST.
(2) Read the "TIRE PRESS" values.
NOTICE:
- It may take up to about 2 or 3 minutes to update the tire pressure data. If the values are not displayed after a few minutes, perform troubleshooting according to the inspection procedure for DTCs C2121/21 to C2125/25.
- If the IDs have not been registered, DTC C2171/71 is set in the tire pressure warning ECU after 3 minutes or more.
- If normal pressure values are displayed, the IDs have been registered correctly.
- If the tire pressure values are not displayed after a few minutes, the IDs may be incorrect or the system may have a malfunction.
- The tire pressure information reception condition can also be confirmed through the multi-information display's tire pressure display screen.
- After all IDs are registered, DTC C2126/26 is set in the tire pressure warning ECU and the tire pressure warning light blinks for 1 minute and then comes on. When the tire pressure warning ECU successfully receives radio waves from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is deleted and the tire pressure warning light goes off.
