Engine General Information and Diagnosis: Bi-Fuel LPG model 1A-28
LPG Control Module
When any of the following DTCs is detected, LPG control module enters fail-safe mode as long as malfunction
continues to exist but that mode is canceled when LPG control module detects normal condition.
NOTE
When LPG control is stopped by fail-safe control, LPG warning light blinks.
