Starting System
\015\012The function of the starting system is to crank the engine at a speed fast enough to allow the engine to start. Heavy cables, connectors and switches are used in the system because of the large currents required.
\015\012The starting system consists of a gear reduced starter motor, battery, remote control switch (ignition switch) and relay.
\015\012Vehicles equipped with automatic transaxle have a transmission range sensor attached to the circuit which prevents operation of the starter motor unless NEUTRAL or PARK are selected.
\015\012Vehicles equipped with a manual transaxle have a start inhibit switch in the starter control circuit, which prevents operation of the starter motor unless the clutch pedal is in the applied position.
\015\012------------------------------------------------------------------------------
\015\012The anti - theft protection system provides protection from unauthorized entry into the passenger compartment.
\015\012The system is controlled by an anti - theft alarm control. When armed, unauthorized entry into the vehicle is detected by lamp switches.
\015\012Once triggered, the system flashes the headlamps, the parking lamps, the alarm indicator, and sounds the horn. In addition, the starter circuit is disabled to prevent starting the vehicle until the system is disarmed.
\015\012 \015\012System Arming
\015\012The system will be armed by the remote entry transmitter when the following input sequence is followed:
\015\012
    \015\012
  1. Turn the ignition switch off and remove the key.
\015\012
    \015\012
  1. Close all doors (unlocked).
\015\012
    \015\012
  1. Press the LOCK button on a transmitter to lock doors. Alarm warning lamp will turn on.
\015\012
    \015\012
  1. Wait for the anti - theft warning lamp to turn off.
\015\012The system will also be armed when the following input sequence is followed:
\015\012
    \015\012
  1. Turn the ignition switch off and remove the key.
\015\012
    \015\012
  1. Open a door. Alarm warning lamp will flash.
\015\012
    \015\012
  1. Lock doors with power door switches. Alarm warning lamp will now glow steadily.
\015\012
    \015\012
  1. Close all doors.
\015\012
    \015\012
  1. Wait for the anti - theft warning lamp to turn off.
\015\012Opening any door will activate the alarm after the alarm is armed.
\015\012 \015\012Disarming an Untriggered System
\015\012The system can be disarmed by performing one of the following procedures.
\015\012
    \015\012
  • Driver or RH front door is unlocked with a key. \015\012
  • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter. \015\012
  • If remaining in the vehicle, turn the ignition switch to ON or ACC position.
\015\012 \015\012System Triggering
\015\012The armed alarm system will be triggered if any door is opened without using a key or a remote entry transmitter to unlock the door first.
\015\012 \015\012Disarming a Triggered System
\015\012Carry out either of the following steps will disarm the triggered alarm system.
\015\012
    \015\012
  • Driver or RH front door is unlocked with a key. \015\012
  • Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
\015\012Two minutes and 45 seconds after the system has been triggered, the horns and exterior lamps will shut off automatically. The system will then reset to an armed state and will trigger again if another intrusion occurs.
\015\012--------------------------------------------------------------------
\015\012Passive Anti-Theft System (PATS)
\015\012The Passive Anti-Theft System (PATS), known as SecuriLock, is fully passive in operation and requires no special procedures by the driver to arm or disarm the system. It is invisible to normal scrutiny and is operated by a transponder within the key body. This communicates with the module through a transceiver mounted around the ignition switch lock barrel.
\015\012The PATS functionality is incorporated within the powertrain control module.
\015\012PATS keys contain an electronic device inside, and are physically larger than a non-PATS key.
\015\012The transponder code reading is carried out when the key is inserted into the ignition lock barrel, and turned from position 0' to position II' or III' to crank the engine. If the PCM receives the correct code signal, the engine will start. Should the code received not be recognized, the engine will not crank as the PATS is still armed and the engine immobilized.
\015\012 \015\012Anti-Theft Indicator
\015\012Whenever the ignition is switched on the anti-theft indicator will remain on for three seconds while the system carries out an initial ignition key-read.
\015\012The anti-theft indicator will flash rapidly for three seconds to indicate the PATS has immobilized the vehicle.
\015\012For additional information on the PATS fault codes, refer to the Diagnosis and Testing section.
Sounds like the cars alarm system has you locked out, do you have a remote to dissarm it?? Can you locate the alarm to see what brand it is... can you call an alarm company to visit the car to try to get it operational?
\015\012If the alarm is set it kills the starter etc.
\015\012To remove it entails the finding of the alrms brain center a small plastic box which is usually mounted and wired in under the dash on the left side.
