Component Inspection

1. Check FTPS.
(1) IG "OFF" and connect scantool to DLC (Data Link Connector).
(2) Monitor "FTPS" parameter with acceleration on service data.
Specification





(3) Does the "FTPS" parameter with acceleration on the service data change?





2. Check PCM.
(1) IG "OFF" disconnect FTPS connector
(2) Connect Scantool and IG "ON" ENG "OFF"
(3) Select simulation function on scantool.
(4) Simulate voltage at terminal 3 of FTPS harness connector.




(5) Does the signal value of FTP sensor change according to simulation voltage?






NOTE:
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by PCM
Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others
