Disassembly
DISASSEMBLY PROCEDURE 1. REMOVE INTAKE VALVE (a) Using SST, compress the inner compression spring and remove the valve spring retainer locks. SST: 09202-70020 SST: 09202-00021 09202-01010 09202-01020 (b) Remove the valve s ...

Transmitter ID1 Operation Stop (C2111/11-C2114/14)
DESCRIPTION The tire pressure warning valve and transmitters that are installed in the tire and wheel assemblies measure the tire pressure of each wheel. The measured values are transmitted to the tire pressure warning ECU and receiver in the vehicle as radio waves. The ECU compares the measu ...

Diagnosis System
DIAGNOSIS SYSTEM 1. DESCRIPTION (a) Blind spot monitor data and Diagnostic Trouble Codes (DTCs) can be read from the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use the Techstream to check for malfunctions and to repair it. 2. CHECK DLC3 (a) Check ...
