Parameters

ID CODE RECEIVED
Indicates whether the central electronic module (CEM) has received a key code (Transponder ID code). This applies whether the key is stored as an approved key or not.
YES = the central electronic module (CEM) has received a key code.
NO = the central electronic module (CEM) has not received a key code.

Hint: However, the key must be of the correct type - intended for this type of Volvo.

ID CODE STORED
Indicates whether the last received key code (transponder ID code) is stored as an approved key code in the central electronic module (CEM) memory.
OK = the last received key code is stored.
Incorrect = the last received key code is not stored.

RANDOM CODE TO TP
Indicates whether the central electronic module (CEM) is transmitting a random code to the key which presupposes that the key code is stored.
YES = the central electronic module (CEM) transmits a random code to the transponder.
NO = the central electronic module (CEM) does not transmit a random code to the transponder.

RESPONSE FROM TP
Indicates whether the central electronic module (CEM) is receiving a response from the key (via the IAU) which presupposes that the key code is stored.
YES = the central electronic module (CEM) receives a response from the key.
NO = the central electronic module (CEM) does not receive a response from the key.

Hint: YES is also displayed for a key belonging to another car of the same type, with the same key ID but a different security code.

TP STATUS OK
Indicates whether all of the following conditions are fulfilled: 1) Key code (transponder ID code) is stored. 2) The key has the car's security code (the key belongs to the car). 3) Communication (random code and response) is OK.
YES = all the following conditions have been met.
NO = all the following conditions have not been met.

KEY TYPE
Indicates whether the ignition key used is a MASTER KEY or a SERVICE KEY.
MASTER KEY = the master key is used as the ignition key.
SERVICE KEY = the service key is used as the ignition key.

KEY NUMBER
Indicates which of the car keys is in the ignition switch. Each key programmed into the central electronic module (CEM) is given a serial number from 1 to 6. NO. 1 - NO. 6.

NUMBER OF KEYS
Indicates how many keys (key codes) are stored in the central electronic module (CEM) memory, 1-6. A maximum of six keys can be stored.

Immobilizer, checking the engine control module (ECM)
Indicates whether the Control area network (CAN) signal containing "Immo ECM data" transmitted is received within a given (maximum) time. This signal is transmitted by the engine control module (ECM) to the central electronic module (CEM) on the high speed network, when the ignition is switched on.
OK = the CAN signal is received within a certain time.
Faulty status = the CAN signal is not received within a certain time.

Immobilizer, start allowed
Indicates whether the Control area network (CAN) signal transmitted by the engine control module (ECM) to the central electronic module (CEM) on the high speed network after an IMMO CHECK is completed, when the ignition is switched on, allows the engine control module (ECM) to be start (POS) the engine or not (NEG).
The following conditions must be met before the engine control module (ECM) will allow the engine to be started. The transponder check must have been successful (the key code, transponder ID, is stored and the security codes for the key and the central electronic module (CEM) correspond). The immobilizer check must have been successful (the codes in the central electronic module (CEM) and the engine control module (ECM) correspond).
Start permitted = the engine control module (ECM) allows start.
Start not permitted = the engine control module (ECM) does not allow start.
