How to repair sometimes engine not starting and no key indicator

How to repair sometimes engine not starting and no key indicator.

Model: All latest model of Hyundai it happen due to immobilizer system  built in

P1676 Immobilizer-Smartra Message Error

Study Component Location

Study General Description

1.Study The sequences of the PIN code storage are as follows.

(1)Study Input the PIN code into the scanner when key teaching process.

The scanner transmits the Encrypted Code to the ECM after converting the PIN code into Encrypted Code.

(2)Study When the ECM gets the firtst key learning command, it transmits the SMARTRA3 learnt command and Encrypted Code to the SMARTRA3

(3)Study If the SMARTRA3 statue is virgin/neutral, the SMARTRA3 stores Encrypted Code in EEPROM and transmits the success message of the Encrypted Code storage.

(If the SMARTRA3 is learnt, the SMARTRA3 compares Encrypted Code transmitted by the ECM with Encrypted Code stored in EEPROM and transmits the (in)correct Encrypted Code message to ECM)

(4)Study If the SMARTRA3 is learnted normally or the Encrypted Code of the registered SMARTRA3 is same as the ECM, the ECM begins operation the Transponder Learning.

(5)Study If the learning of the first transponder, the ECM stores the Encrypted Code in its EEPROM and converts state into learnt state.

2.STUDY The SMARTRA3 learning :

(1)Study starts with EMS request of PIN from scanner through the key teaching procedure.

(2)Study is possible in case that the status of SMARTAR is “virgin” or “neutral “.

(3)Study In case that the SMARTRA3 is “learnt”, the SMARTRA3 will transmits the information if PIN inputted from scanner is same as the PIN in SMARTRA3.

(4)Study is possible regardless of key status.

3.Study The sequence of the SMARTRA3 confirms are as follows.

(1)Study After communication with the SMARTRA3, the ECM transmits the random number with requirement of the TP ID information.

(2)Study The SMARTRA3 encryptes the random number and transmits the result(Encrypted Random Number) to the ECM with TP ID information.

(3)Study The ECM compares the result transmitted from the SMARTRA3 with the result calculated by ECM.

And If result are coincided with each other; the ECS concludes the valid confirmation of the SMARTRA3.

DTC Description

The ECM sets DTC P1676 if there's any fault in message from SMARTRA to ECU

What is the Problem if Engine Hard to Start in Morning

What is the Problem if Engine Hard to Start in Morning.?
How to check of this problem?
Model: Hyundai Sonata (FL).
Year Model: 2010
Fuel: Gasoline
Displacement: 2400cc
Subject: Engine Hard starting especially in the morning.
1) Condition

1. Engine hard starting in morning, at the same time after driving the car and park after a few minute try to start it cannot start immediately.

2) Cause

1. immobilizer key.

3) Diagnosis

1. Scan tool check
   Trouble Code.
   a) P1693 – Immobilizer Transponder.
   
   Almost all Hyundai model are built in with anti theft gadget that what we call immobilizer system. consist of ECM, the SMARTRA3 and the ignition keys with built in transponder.
      The ECM carries out the check of ignition key by especial encryption algorithm with SMARTRA3 and transponder. the encryption algorithm (between ECM and SMARTRA3) is used one offered from Bosch. the encryption algorithm (between ECM and Transponder) is Hitag2 type witch is high level.when ignition ON, the ECM executes the key authentication. The engine can be started in case of the success in SMARTRA3 and key Authentication.
      The Key teaching procedure start with ECM request of pin from scanner. The ‘virgin’ ECM stores the pin and the key learning can be started. the '”learnt” ECM compares the PIN from tester with the vehicle password in transponder. If the data is correct, the learning can be started. Scanner request the learning of the first key, the SMARTRA3 is registered at first and then first key is registered by ECM. If the SMARTRA3 status is learnt and pin number is different , the SMARTRA3 will return the incorrect pin data to the ECM. in this case, the ECM can’t execute the key learning process.
   
2. Observation the key indicator from control takes a second to appear this abnormal. the normal is takes 3 second only.
   
3. Check and reprogram with new key.
   
4. The indicator normalize = Ok

3. Check all the system, lights and gear = confirm the automatic transmission cannot shift.due to shift lock solenoid not working.
4. Check with schematic diagram for shift lock solenoid.
   = From the brake switch check for the power
   disconnect the socket and check, Switch on the key = Ok (B+) 
   = Check the switch = OK
   = Pull out the console box assembly where in the shifting lever mounting under it.
   = Check the wire connector of shift solenoid.
   =Disconnect the socket and check if there is power from brake switch and ground from ECU = Ok
   = Direct with power and ground the solenoid wire to check if this will functioning = No, confirm that solenoid busted.

4) Repair Guide
