S y s t e m C h e c k
1. Connect the HDS to the data link connector.
2. Turn the ignition switch ON (II).
3. Monitor the System Check in the Immobilizer Info with the HDS.
4. If the HDS displays the "Immobilizer system is normal", the immobilizer system is OK. If the HDS displays any other messages, check as
follows:
Status Log No. System Check Possible Failures
A-1 Immobilizer system
is not normal
• This key is not registered in the immobilizer unit. Try to register keys by using "KEYS".
• The communication was not good between the antenna and the immobilizer key by
influence of metal such as key chains.
• The communication was not good between the antenna and the immobilizer key by
battery voltaqe low.
A-2 Immobilizer system
is not normal
• Intermittent interruption between transponder and immobilizer unit.
• The immobilizer key type is different. It is not for this vehicle but for another one or for
other company's one.
• Key failure (transponder failure)
• The communication was not good between the antenna and the immobilizer key by
influence of metal such as key chains.
• The communication was not good between the antenna and the immobilizer key by
battery voltage low.
A-3 Immobilizer system
is not normal
• The ignition switch was turned on with a non-immobilizer key.
• The immobilizer key type is defferent. It is not for this vehicle but for another one or for
other company's one.
• Key failure (transponder failure)
• The communication was not good between the antenna and the immobilizer key by
influence of metal such as key chains.
• The communication was not good between the antenna and the immobilizer key by
battery voltage low.
• Immobilizer unit failure
B-1 Immobilizer system
is not normal
• The PCM was not registered. Try to register the PCM by using "REPLACE PCM".
• The communication was not good between the PCM and the immobilizer unit by battery
voltage low.
• The communication was not good between the immobilizer unit and the PCM by
influence of some noise.
B-2 Immobilizer system
is not normal
• The PCM was not registered. Try to register the PCM by using "REPLACE PCM".
• The communication was not good between the PCM and the immobilizer unit by battery
voltage low.
• The communication was not good between the immobilizer unit and the PCM by
influence of some noise.
D-1 Immobilizer system
is not normal
• Harness short from the PCM to the immobilizer unit. (S-net line short)
• The communication was not good between the PCM and the immobilizer unit by battery
voltage low.
• The communication was not good between the immobilizer unit and the PCM by
influence of some noise.
• Immobilizer unit failure
• PCM failure
D-3 Immobilizer system
is not normal
• Blown fuse
• Harness open from the PCM to the immobilizer unit.
• The communication was not good between the PCM and the immobilizer unit by battery
voltage low.
• The communication was not good between the immobilizer unit and the PCM by
influence of some noise.
• Immobilizer unit failure
• PCMfailuer
