Was “Engine and Emission Control System Check”
performed?
Go to Step 2.
Go to “Engine and
Emission Control
System Check”: Bi-Fuel
LPG model.

LPG fuel injector power supply circuit check
1) Turn ignition switch to OFF position and then disconnect
connectors from LPG fuel injectors.
2) Check for proper terminal connection to LPG fuel
injector connectors.
3) If connections are OK, turn ignition switch to ON
position.
4) Check that voltage between LPG fuel injector power
supply circuits (B1, B2 and B3) and vehicle body ground
is battery voltage.
Is it in good condition?
Go to Step 3.
Repair or replace LPG
fuel injector power
supply circuit.

LPG fuel injector control circuit check
1) Turn ignition switch to OFF position and then disconnect
connectors from LPG control module.
2) Check for proper terminal connection to LPG control
module connectors.
3) If connections are OK, check that LPG fuel injector
control circuits (D1, D2 and D3) are as follows.
• Wiring harness resistance of each LPG fuel injector
control circuit is less than 1
Ω
.
• Insulation resistance of each LPG fuel injector control
circuit between LPG fuel injector connector and
vehicle body ground is infinity.
• Insulation resistance of wire harness is infinity
between each LPG fuel injector control circuit terminal
and each terminal at LPG fuel injector connector.
• Voltage of each LPG fuel injector control circuit is 0 –
1 V with ignition switch in ON position.
Is it in good condition?
Go to Step 4.
Repair or replace LPG
fuel injector control
circuit.
