The MIL has two types of blinks a long blink and short blink The long blink lasts for 1 3 seconds the short blink lasts for 0 5 sec onds When two long blinks occur and five short blinks that problem code is 25 two long blinks 20 blinks five short blinks 5 blinks Then go to the flow chart and see problem code 25 e When the Engine Control Module ECM stores some failure codes the MIL shows the failure codes in the order from the lowest number to highest number For example when the MIL blinks once then blinks seven times two failures have occurred Follow the flow chart for failure codes 1 and 7 Number of PGM FI MIL Causes Symptoms Refer to blinks page 0 e Open circuit at the power input and lt Engine does not start ground wires of the ECM O e Blown sub fuse D 75 A e Faulty main relay No e Open circuit in the main relay related cir blinks cuits lt Faulty engine stop switch e Open circuit in the engine stop switch related circuits e Faulty ECM lt Blown main fuse 30 A e Open circuit in the MIL wire lt Engine operates normally O e Faulty ECM No blinks e Short circuit in the MIL wire lt Engine operates normally IN e Faulty ECM Blinking e Short circuit in the service check connector lt Engine operates normally IN wire Stay lit 1 e Loose or poorly connected MAP sensor lt Engine operates normally 8 16 ike connector Cy lt Open or short circuit i
