e. Check that the tire pressure warning light is lit and one of the pressure data shows 120 kPa (1.2 kgf/ sq.cm, 17 psi) on the LEXUS hand-held tester.

HINT:
- If the above is identified, the transmitter is registered to "Main".
- If not, set the tire pressure warning switch to "2nd" and perform the same procedure.
- If the above is identified with the tire pressure warning switch set to "2nd", the transmitter is registered to "2nd".
- If it cannot be registered to any of "Main" and "2nd", perform troubleshooting according to the Problem Symptoms Table.
