Lighting Up Of The Led Without The Ignition Key - PEUGEOT ACI -100 Workshop Manual

DIAGNOSIS BASED ON TRANSPONDER LED
1. LIGHTING UP OF LED WITHOUT THE IGNITION KEY
A succession of one flash per second indicates that the vehicle is protected against theft. (If the
unit is programmed).
This deterrent function is operational for 48 hours after switching off the ignition.
After 48 hours the LED goes out to avoid discharging the battery, but the immobiliser system
remains active.
Even in the case of the battery being disconnected the system remains active.
Upon reconnection of the battery the memorised keys will allow the car to be started, however
long the period of disconnection.
2. LIGHTING UP OF LED WHEN TURNING ON IGNTION WITH MASTER KEY.
0.5 sec
Lighting up for 0.5 sec followed by a certain number of flashes indicates the number of keys
programmed (including the master key) 2 flashes according to the original configuration.
The number of flashes (2 minimum – 3 maximum) corresponds to the number of keys programmed.
2 sec
A single lighting up of LED for 2 seconds indicates that the unit is not programmed (to turn at
2000rpm maximum).
3. LIGHTING UP OF LED WHEN TURNING ON THE IGNITION WITH ONE BLACK
KEY
The lighting up of the LED using a black key consists of three successive phases when turning on
the ignition:
Phase 1 : gives information on the state of the system
Phase 2: gives information concerning the diagnosis.
Phase 3 : gives information concerning authorisation to start
