- replace the FUEL CONTROL UNIT P19 (Ref. AMM TASK 49-32-11-000-001) and (Ref. AMM TASK 49-32-11-400-001).
(a) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/F6, F7 to the FUEL SHUTOFF SOLENOID VALVE P13/1, 2 (Ref. ASM 49-61/02).
- do a check and repair the wiring from the ECB (59KD) AB/H10, H11 to the FUEL CONTROL UNIT P19/1, 2 (Ref. ASM 49-61/02).
(b) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. AMM TASK 49-61-34-400-001).

UNDERSPEED - FUEL CONTROL UNIT (8022KM)
or
NO FLAME - FUEL CONTROL UNIT (8022KM)
or
NO ACCELERATION - FUEL CONTROL UNIT (8022KM)
