NOT GETTING ANY DATA.

Is base station seeing data?
Is truck loaded onto base station?
Does sim number on truck match ID on top end?
Check truck still has an aerial and that it is connected to the PCB
Check to see if truck is talking to base station with psion.
Has original sim been put back in if board has been changed.

TRUCK NOT LOGGING OFF.

Check configuration with psion, is unit seeing input all the time. Could be configuration, could be incorrect settings or damaged microswitches/proximity switches.
Has timeout setting defaulted? i.e., truck will never time out

RELAYS WELDED

Check for loose crimps and connections on relays.
Check for burnt wires.
Has truck got a slave relay fitted?
Do relays fitted to truck comply with DD spec?
Has the truck been fitted (or Retrofitted) with additional lights, heaters or other high power devices that are switched by this relay. If so, has the “new” current been measured?

TRUCK KEEPS CUTTING OUT.

Check configuration with psion, is truck seeing any inputs? If not truck will not time out whilst in motion (12v).
Could be faulty sleep timer, not as common if sleep timer is fitted with green/orange wire. If the sleep timer is suspected then if the truck cuts out 10-20 secs after engine “start” (or cranking) then it is almost certainly a low battery in the sleep timer/voltage stabiliser.
If sleep timer does have green/orange wire fitted check the fuse has not blown.

TRUCK WON’T START/ NOT LOGGING ON.

CHECK:

Check fuses have not blown.
Has driver pressed sleep timer button if 12v truck?
Check for good negative on truck on DD system.
Check for good positive supply on truck.
Is there a feed into and out of sleep timer, (red + black supply in, slate + black out) ?
Check for 5v supply in top box on red + blue wire’s.
Is L.E.D flashing in top box?
Is L.E.D flashing in interface?
Check interface does not keep blo wing newly replaced fuses.
Is there a feed to interface (pin 2 + 3 )?
Check card reader is not damaged.
Check all keys on keypad work using psion.
Check truck is set up to use 5 digit code or 5 + 1.
Has truck lost its pin file? If so try 1,2,3,4,5 ENT (this is a default setting).
Has truck been set up to read specific card?
Is configuration correct i.e. traction, lift, batt. monitor?
If key is removed (12v) truck will not start if seeing an input.
Check for damage or incorrect positioning of micro-switches / proximity switches etc.
Truck will not log on if batt. monitor is not seen.
Check for loose connections e.g. pins to interface, loose wires, bad crimping, dry soldered joints, burnt or squashed wires.
Has the truck been suppressed where appropriate?
