SERIES, RANGERISSUE Occasionally, there are reports of the Malfunction Indicator Lamp MIL Check Engine Lamp CEL or Service Engine Soon SES lamp being lit with no Self Test codes in Continuous Memory. An explanation of three digit EEC IV Self Test Codes has been developed along with reasons for the MIL lamp being lit with no accompanying Continuous Memory Self Test codes. ACTION Refer to the following explanation of three digit EEC IV Self Test Codes to determine why the MIL lamp is sometimes lit with no accompanying Continuous Memory Self Test codes.

MIL LAMP ACTIVATIONFollowing is a list of reasons why a technician may see the MIL lamp lit with no accompanying Continuous Memory Self Test codes. Esx Server 3.5 Serial here.

Ford Scanner (F-Super)' title='Ford Scanner (F-Super)' />While both of these will test for various hard faults that are present when the test is run, the processor continuously monitors various operating parameters whenever the engine is running. If the processor detects a problem, it will store a Continuous Memory code and light the MIL. These Continuous Memory codes are put out during KOEO Self Test after any codes associated with hard faults are output. Self Test Codes are displayed by flashing the MIL. They are also output as voltage pulses on the Self Test Output STO circuit in the Self Test connector. In either Self Test mode, all codes are output twice and in KOEO, the hard fault codes are separated from the Continuous Memory codes by a separator pulse. A technician that is unfamiliar with the EEC Self Test can mistakenly believe that continuous Memory codes are not present when they really are. He may run KOER Self Test and get a pass code lll and not realize that KOEO Self Test must be run to receive any Continuous Memory codes. He may run KOEO Self Test while counting MIL flashes and misinterpret the repeated hard fault pass code lll to mean that Continuous Memory does not contain any codes. Inadvertent Erasure Of Continuous Memory Self Test Codes. Continuous Memory Self Test codes are erased by ungrounding STI before KOEO Self Test is complete and all KOEO and Continuous Memory codes have been displayed. It is possible to inadvertently erase Continuous Memory codes by ungrounding STI without realizing that KOEO Self Test is not complete or the processor has not finished displaying all the codes. The EEC Self Test codes are not only used by service technicians, they are used as a final system test in the assembly plants. To make this test as efficient as possible, Self Test codes are output as a very fast, short pulsewidth signal before the codes are displayed by the flashing MIL. These FAST codes can only be interpreted by end of line equipment or code reading testers like Fords Self Test Automatic Readout STAR testers. The EEC IV processor puts out both 2 digit and 3 digit Self Test codes in both formats, FAST pulsewidth mode and SLOW pulsewidth mode. While all STAR type testers display 2 digit codes, the original STAR tester cannot display 3 digit service codes. If the STAR tester is used on 3 digit service code applications, the display will be blank but the tester will beep. The beeps can be counted to determine service codes. The SUPER STAR II tester will only display 3 digit service codes in FAST code mode. If slow code mode is used on 3 digit service code applications, the display will be blank but the tester will beep. The beeps can be counted to determine service codes. For more information on running Self Test, refer to the EEC IV Quick Test Procedures and Appendix section of the Powertrain ControlEmissions Diagnosis Service Manual. Since certain STAR testers are capable of reading and displaying fast codes before the slow codes are finished being output on the MIL, a technician can assume that since he sees codes displayed, he can unground STI and move on. If he ungrounds STI before all slow codes are output, Continuous Memory will be erased and could put out a pass code lllll the next time KOEO Self Test is run. The technician may also realize that his tester is in SLOW mode after he has initiated the KOEO test and stop the test to change tester settings. Another possibility is that another person, a vehicle owner or another technician, could have erased the codes before the technician reporting the situation has run Self Test. In any of these situations, the vehicle must be driven until the Continuous Memory codes are reset. The Concern That Set The Continuous Memory Code Is No Longer Present. The EEC processor will erase a Continuous Memory code if the concern that caused it has not been present for 4. A warm up cycle occurs when the vehicle is started with the coolant temperature below 1. Picasa 3 Photo Editor Free Download For Windows Xp. F 4. 9 C and then shutdown with the coolant temperature above 1. F 6. 6 C. If a vehicle is brought in for service with a MIL complaint and the vehicle is driven or otherwise allowed to warm up before Self Test is run, the code may be cleared before the technician tests it. Grounded STOMIL Circuit. The processor controls the MIL by grounding the STOMIL circuit Pin 1. If this circuit shorts to ground, whether the processor is controlling it or not, the MIL will be lit. Starting in 1. 99. MIL, it will hold it on for a minimum of 1. If the MIL flashes quickly, the concern is probably the STOMIL circuit shorting intermittently to ground. Engine Running In HLOSThe EEC processor will enter Hardware Limited Operation Strategy HLOS if it detects a problem that could cause further damage to the system. Under HLOS, the processor modifies its operating strategy so that certain functions are disabled but the vehicle can be safely driven in for service. If the vehicle is in HLOS, Continuous Memory codes will not be set and Self Test cannot be initiated. However, Continuous codes that were set before the processor entered HLOS will be retained. Misinterpretation Of MIL Bulb Check. The MIL will light as a bulb check if the key is on and the engine is not running. If the engine is running and stalls or stops for any reason with the key on, the MIL will be lit and no Continuous Memory codes will be set. When the key is first turned on, the MIL will stay lit briefly after the engine is started as part of the bulb check feature. MIL Flashes During Self Test. The circuit that controls the MIL is also the Self Test Output STO circuit that goes to the Self Test connector. The MIL will flash during Self Test as the STO circuit is cycled on and off. This is normal and no Continuous codes are set. Processor KAM Is Erased Or Fails.
