Replacement

Problems and Replacement Parts:

Symptom	Kit	Is a scan tool required?
All keys lost	Blank key (4)	YES
Antenna coil unit malfunction	Antenna coil unit	NO
ECM malfunction	PCM (ECM)	YES
Ignition switch malfunction	Ignition switch with antenna coil unit	YES
Unidentified vehicle-specific data appears	Key, PCM (ECM)	YES
SMARTRA unit malfunction	SMARTRA unit	YES

ECM and SMARTRA Replacement. If the ECM is faulty, replace it with a "clean" or "neutral" ECM. All keys must be learned to the new ECM. Keys that are not programmed to the ECM are invalid for the new ECM (refer to the key learning procedure). Vehicle-specific data must be kept unchanged due to the unique transponder programming. If the SMARTRA is faulty, the SMARTRA must be learned. The new SMARTRA replaces the old one, and the SMARTRA must be learned.

   Precautions before replacement (keys and additional registration)

   

ECM Neutralization. The PCM (ECM) can be set to the "neutral" state using the tester. A valid ignition key is inserted, and after turning the ignition ON, the PCM (ECM) requests vehicle data from the tester. Communication messages are described in "Neutral Mode". After the PCM (ECM) successfully receives the data, it is neutralized. The ECM remains locked. Neither the emergency home mode nor "double ignition" is accepted by the PCM (ECM). Key learning is performed according to the procedure described for the primary PCM (ECM) module. Vehicle-specific data must remain unchanged due to the unique transponder programming. If the data must be changed, new keys with a virgin transponder are required. This function is intended for neutralizing the PCM (ECM) and keys. For example, if a key is lost, neutralize the PCM (ECM), then learn the keys (refer to "What to Do If"). If the key and PIN code can be set to the PCM (ECM) "neutral" status with the scan tool. If incorrect vehicle data is sent to the SMARTRA three times in succession or with interruptions, the SMARTRA will reject the request to enter neutral mode for one hour. Disconnecting the battery or other manipulations cannot shorten this time. After the battery is reconnected, the timer starts again for one hour.

SMARTRA EMS Neutralization. The SMARTRA can be set to the neutral state by the tester. The ignition key (regardless of key status) is inserted and after IGN ON. When the correct vehicle password is received from the GST, the SMARTRA can be neutralized. SMARTRA neutralization is possible if the DPN matches the entered value. Per VAT. If the SMARTRA status is neutral, the EMS maintains the locked state, and starting is not possible with "double ignition". If the vehicle password is changed, a new original transponder must be used only. And in the case of a primary key, after learning the vehicle key, it can be used. If incorrect vehicle data is sent to the SMARTRA three times in a row or with interruptions, the SMARTRA will reject the request to enter neutral mode for one hour. Disconnecting the battery or other manipulations cannot reduce this time. After the battery is reconnected, the timer starts again for one hour.
