TIPS & HINTS

SYSTEM IDENTIFICATION

106=CPH

206=Had BSI from the start but only had MUX from 51 Reg on (build code 9064 on) the

design of the stalks gives it away, plip keys also different as it has a square appear-

ance.

306=Never had MUX but late ones from approx V reg had HF plips and a CPH under the

dash (passenger compartment protection unit) which worked locking and plips in one

unit.

307=all BSI + MUX

406=had BSI + MUX from facelift (honey comb grill & boot and rear lights)

806=same as 306

807=All BSI + MUX

607=All BSI + MUX

Partner=Up to 2001 CPH, BSI from approx 2001 and has MUX like 406

Expert =All CPH

Boxer =All code1/2 (Fiat system)

Programming keys on BSI 2 may result in a vehicle that subsequently loses all electrical

device operation (lights, wipers etc)- this is caused by the BSI unit waking up incor-

rectly after programming causing it to switch off all actuator outputs. Therefore once

keys have been programmed on BSI2 equipped vehicles the system must been set to

sleep (open drivers window, remove keys from ignition, shut drivers door and leave for

30 mins) and then woken using the sidelight switch only (lean in through the open driv-

ers window and turn on sidelights.) All CPH systems, and some Imm 1/2, have connec-

tions to doors, boot and bonnet. Key programming may not be allowed if a door is open

or "thought" to be open- therefore a faulty bonnet switch will cause a failed key pro-

gramming session.

To minimise the possibility of the BSI unit corrupting it's own software after download/

programming or disconnection a certain procedure must be adopted to sleep and wake

the BSI in the cleanest possible way. This will prevent the possibility of a complete

dashboard or BSI derived electrical failure and also a current draw problem caused by

failure to enter power save or sleep mode.

Switch off all electrical devices and put drivers window down. Make sure the AD100 is

disconnected (a diagnostic session will keep the BSI unit awake) and make sure the

bonnet is up, the key is out of the ignition and all of the doors are shut. Wait for 3 min-

utes. Disconnect the battery and wait for 30 seconds

Re-connect the battery, wait 10 seconds and without opening any doors turn on the

sidelights through the drivers open window. (the "lights on" chime should sound)

Start the engine and check all systems are functioning.

Sudden voltage spikes (as with jump starting) can also corrupt the BSI unit.

Some 607 vehicles have two batteries (other one is in the boot under the R/H trim)

406 Interior fuse box Fuse 25 (immobiliser, gearbox, engine, interior light, clock) blows

intermittently. This fuse covers immobiliser function so you will find that if it is blown

the car will not start but once started the fuse can blow (or be removed) without the

car stopping. Fault is caused by a water leak in through the aerial onto the interior light

assembly.
