Engine General Information and Diagnosis: Bi-Fuel LPG model 1A-24
LPG Control Module
1) With ignition switch turned OFF, connect SUZUKI
scan tool to DLC.
2) Turn ignition switch to ON position.
3) Erase DTC and pending DTC according to
instructions displayed on scan tool. Freeze frame
data is cleared together with DTC. Refer to scan tool
operator’s manual for details.
If communication between scan tool and LPG control
module is not possible, go to “Troubleshooting for
Communication Bus Off”: in Section 10H.
4) After completing the clearance, turn OFF ignition
switch and disconnect scan tool from DLC.
NOTE
DTC and freeze frame data stored in LPG
control module memory are also cleared in
the following cases. Be careful not to clear
them before recording them.
• When the same malfunction (DTC) is not
detected again during 40 engine warm-up
cycles (refer to Warm-Up Cycle of “OBD
System Description”: Bi-Fuel LPG model.
