Trouble code
Definition
Check / solution
100
Lambda to long to rich.
Check when operating on petrol and LPG that there is good lambda
signal movement.
101
Lambda to long to lean.
Check when operating on petrol and LPG that there is good lambda
signal movement.
102
Lambda to long to lean during open
loop.
Check when operating on petrol and LPG that there is good lambda
signal movement.
110
T-ECT>= 171°C
Check if the ECT sensor (blue) in the reducer is connector is connected
to ground.
111
T-ECT>= -40°C
Check if the ECT sensor (blue) in the reducer has a power connection.
120
T-LPG>= 171°C
Check the ground connection of the Pressure/temperature sensor in the
filter unit.
121
T-LPG>= -40°C
Check the power connection of the Pressure/temperature sensor in the
filter unit.
150
Psys<= Low_Level
Based on a pressure drop in the system, this can be caused by an empty
LPG tank, incorrect solenoid valve, polluted filter or incorrectly adjusted
pressure.
160
ECM-VSI not activated
Activate the LPG computer with the diagnostic program, using the F11
function key.
180
T-Board >= 90°C
LPG computer circuit board to hot, replace the VSI computer in a cooler
area.
181
Battery voltage to high
Check board voltage / alternator output and condition of the battery.
210-220-230-240-250-260-270-
280
VSI injector
overload
Injector current to high, check for short circuiting
211-221-231-241-251-261-271-
281
VSI injector
noload
Injector current to low, check for bad connections.
310
Adjusted pressure on idle out of
range
Adjust the idle pressure to the value shown by parameter “ Idle Level “
311
Programm error during flahing the
memory
Check parameter settings, contact Prins Autogassystemen.
320
Psys voltage to low
Check the ground connection of the Pressure/temperature sensor in the
filter unit.
321
Psys voltage to high
Check the power connection of the Pressure/temperature sensor in the
filter unit.
322
Psys > 3,5 Bar
Check the coolant temperature (T-ect) and the evaporator for leakage of
the first stage.
330
unexpected parameter change
Contact Prins Autogassystemen.
340
reducer warms up to slow
Check the water connections / circuit.
341
Gas leakage, system pressure is less
then 1.25 bar after 4 hours when the
engine is not running
Check the system for gasleakage.
-
System switches to LPG but
engine stalls immediately.
LPG tank empty ?
Lock-off valves open ?
-
No injection timing on LPG ( 0
Msec.)
Check the injection module.
-
The LPG system switches
constantly between LPG and Petrol
- Check coolant system for air.
- T-ect sensor in the evaporator malfunction.
-
Engine hesitates on high revs, and
not running on all cylinders. Engine
runs good on idle.
Check for kinked or jammed LPG hoses (between VSI injector and
couplings).
Check for blocked inlet couplings.
-
Switch LED’s don’t lit up
Check the main fuse of the VSI system
Check ignition+ (VSI wire 13)
-
Fault codes when turning the
ignition off ( key out the ignition )
Caused by different switch off times between ignition+ and injector
power.
Connect VSI wire 13 to the petrol injector feed instead of ignition+.
-
The orange LED on the switch
flashes
Activate the LPG computer with the diagnostic program, using the F11
function key.
-
The LPG system switches to LPG
but engine stalls immediately
LPG tank empty?
-
Not running on all cylinders on lpg
Check parameter 10, number of cylinders.
-
No injection times on lpg
Check the connections of the injection module.
-
Injection time “falls” to 0 mSec on
LPG
Check the injection module.
-
Check engine while running on
LPG, injector circuit malfunction,
no lambda control (limb home)
Replace injection module
-
Not starting / running on petrol
Check the connections of the injection module.
