Hi All When using the DDEC Diagnostic Request Switch to Flash out the DDEC errors codes on the dash lights - Is there any way to tell the: Historical DDEC codes - those errors that are logged to memory but are no longer active errors or causing a current problem and Active DDEC errors - those that are causing the CHECK ENGINE LIGHT TO STAY ON Someone once told me that history codes flash on the STOP ENGINE and ACTIVE codes flash on the Check Engine light -- WRONG I can force an active TPS DDEC error 22 by pulling the connector off my throttle - only the check engine light flashes - Check engine light on contantly - diagnostic switch flashed all errors on the check light (active #22 and all History codes) someone told me to leave the batteries disconnected for 24 hours to erase historical codes -- wrong - tried that - that doesn't work either I certainly don't want to go out and buy a PROLINK and DDEC cartridge just to see my ACTIVE errors separated from my historical errors - or just to reset my history codes nor do I wish to buy the cheaper / less functioning PDL (Pocket Diagnostic Link adapter and software to run on a PALM Pilot - just to see the error codes separated - the only parm that the PDL can change is to reset the historical code - Big Deal for a lot of money Help Pete RTS/Daytona | ||

TM9-2320-360-20-3 Section 2 BASIC KNOWLEDGE REQUIRED (Cont’d) E. GENERAL DIAGNOSTIC INFORMATION As a bulb and system check, the “Check Engine” and ‘Check Gauges” lights will come on for 5 seconds when the ignition switch is first turned on. If the “Check Engine” light comes on during vehicle operation, this indicates the self diagnostic system has detected a fault. When the diagnostic request switch is held, the diagnostic system will flash the orange lights located on the vehicle’s dash. The light will be flashing the code(s) indicating the problem area(s). If the “Check Gauges” light comes on during vehicle op- eration, this indicates the DDEC System hasdetected a potential engine damaging condition. The engine should be shutdown immediately and have the engine checked for the problem. *Active codes will be flashed on the “check gauges” light in order from most recent to least recent occurrence based on engine hours. If there are no active codes, a code 25 will, be flashed. *Inactive codes will be flashed on the “check engine” light in order from most recent to least recent occurrence based on engine hours. If there are no inactive codes, a code 25 will be flashed. * FLASHING CODES SHOULD BE DONE WITH THE ENGINE NOT RUNNING AND IGNITION ON. * A diagnostic code indicates a problem in a given circuit (i.e., diagnostic Code 14 indicates a problem in the oil or coolant tem- perature sensor circuit. This includes the oil or coolant temperature sensor, connector, harness, and Electronic Control Mod- ule (ECM). The procedure for finding the problem can be found in Diagnosis Chart Code 14. Similar charts are provided for each code. Remember, diagnosis should always begin at the starting chart (START). For an oil or coolant temperature sensor problem, it will quickly lead you to Chart 14 -but first it gets you to verify the code/symptom. Since the self-diagnostics do not detect all possible faults, the absence of a code does not mean there are not problems in the system. If a DDEC Ill problem is suspected, even in the absence of a code, go to START anyway. This chart can lead you to other charts which can aid in the troubleshooting process- where DDEC III problems may occur but do not generate a code. Basic mechanical checks, however, are not covered in this guide, refer to Chapter 2, Vehicle Troubleshooting. D. CLEARING CODES This can only be done using the Diagnostic Data Reader (DDR). Refer to the DDR Instruction Manual for details. Note that removing the battery cables will not clear codes HTH | ||

Pete Surely with all the help you give people on this board there is a bus nut in FL that will let you use their ProLink to find out the codes. Come to the G.L.A.S.S. rally in MI (May 25 to 29 I think) and I will have my Prolink there. Bill |
