Specification : Approx. 8.6 Ω
Is the measured resistance within specifications ?
YES
Go to " Check SMARTRA" as below
NO
Check for open or short in harness between SMARTRA and Antenna coil, repair or replace as necessary. And then, go to "Verification of Vehicle Repair" procedure.
Ignition " ON" & Engine " OFF "
Perform the Neutral, Teaching, and Password teaching/ changing mode according to 2. ECM neutalization, 3.Key Teaching Procedure, 4. Password teaching/Changing in "Reference Data" described in General Information
Be sure that PIN code is prepared before performing neutral mode.
Is Key teaching completed ?
YES
Go to "Verification of Vehicle Repair" procedure.
NO
Substitute with a known-good SMARTRA and check for proper operation. If the problem is corrected, replace SMARTRA and go to "Check ECM" as below
In case of faulty SMARTRA, there are no special procedures required. A new SMARTRA device simply replaces the old one. (There are no transponder-related data stored in this device.)
Ignition " ON" & Engine "OFF"
Perform Key Teaching Procedure in "Reference Data" described in General Information.
Is the Key teaching completed ?
YES
Thoroughly check connectors for looseness, poor connetion, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to " Verification of Vehicle Repair" procedure.
NO
Substitute with a known-good ECM and check for proper operation. If the problem is corrected, replace ECM and then go to " Verification of Vehicle repair" procedure.
1. Don’t forget to prepare for the PIN of the vehicle before removing ECM from the vehicle.
2. Remember that substituting with a known-good ECM should be followed "The things to remember before repair(1)" in "Reference Data in General Information".(In case of faulty ECM, it has to be replaced with "VIRGIN" or " NEUTRAL" ECM.)
3. Strongly recommend to register PIN which is given by HMC or the regional office when replacing a new ECM.
