Component Inspection

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





(3) Is the "FTPS" parameter on the service data O.K?
YES
1) Go to "Check ECM" as follows
NO
1) Substitute with a known-good FTPS and check for proper operation.
2) If the problem is corrected, replace FTPS and go to "Verification of Vehicle Repair" procedure.
2. Check ECM
(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 1 of FTPS harness connector.




(5) Does the signal value of FTP sensor change according to simulation voltage?
YES
1) Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.
NO
1) Substitute with a known-good ECM and check for proper operation.
If the problem is corrected, replace ECM and go to "Verification of Vehicle Repair" procedure.

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