Monitor Scantool Data

Monitor Scantool Data

1. Check transponder and ECU status
(1) IGN "ON" & Engine "OFF" with key intended to register
(2) Monitor the "ECU, KEY, Smartra STATUS" Parameter on the Scantool.
A. Specification : 'LEARNT'




Fig.1) This data show that 3 keys have been taught, ECU has been learnt, Key in key cylinder has been learnt and SMARTRA3 has been learnt.
(3) Has the "SMARTRA" status been learnt?
YES
- Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, damage on the ECM or SMARTRA.
And has not erased this DTC which is not erased previous repair. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
- Go to "Check SMARTRA" procedure.
2. Check SMARTRA
(1) IGN "ON" & Engine "OFF"
(2) Neutralize SMARTRA with scantool.
(3) Neutralize ECM and Register transponder key by scantool.

CAUTION:
** Pin code is required to Neutralize SMARTRA & ECM and to Register transponder key.

(4) Are Neutralizing and Registering Key completed normally?
YES
- Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, damage on the ECM or SMARTRA. Or It has not been erased this DTC in previous repair. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
- Substitute with a known-good SMARTRA and perform the Key teaching.
If the problem is corrected, replace SMARTRA and then go to "Verification of Vehicle Repair" procedure.

CAUTION:
If the SMARTRA3 is only replaced using an existing key and ECM, after replacing the "virgin" or "neutral" SMARTRA3, reteaching is possible by key Learning mode of scanner. In this case, all existing key must be retaught.
If SMATRA3 is replaced to another one (used at other vehicle), it can only recycle its neutralized first before replacing.
