Slow city driving in the rain today when, with no warning or mishap, the "Service Engine Soon" light came on. No symptoms, car runs fine. Tried the ignition key on-off-on-off-on trick and got the "Service Engine Soon" light to blink out codes: 12 43 55. Alpar.com interprets this as two codes, 12 and 43 with 55 as "end of codes" delineator. The 12 code is: "Battery or Computer recently disconnected" The 43 code is: "Peak primary coil current not achieved with max dwell time...OR...Cylinder misfire...OR...Problem with power module to logic module interface" Yikes! A few days ago I had a mechanic repair a slight leak of transmission fluid at the radiator connection... perhaps he disconnected the battery as a safety measure before doing the work. But the other items?? Anybody have any idea how I could differentiate among the three possibilitiues for code 43? Also, is there a way to reset the system so that the "Service Engine Soon" light will go out? Thanks.
