The internal mode switch indicates the Transmission Control Module (TCM) which gear position the vehicle operator has selected. The internal mode switch consists of 5 separate hall effect switches. Each hall effect switch is supplied with a 9 V reference circuit and a signal circuit from the TCM. Each signal circuit for each gear selector position will have either a voltage reading of 0.70–0.96 V indicating On or 1.68–2.38 V indicating Off. The voltage values on each internal mode switch circuit will change and are dependent on the position of the gear selector. The state of each internal mode switch A/B/C/P/S signal circuit is displayed on the scan tool. The Diagnostic Trouble Code (DTC) will be set when the TCM has detected the internal mode switch C signal circuit voltage is less than 0.7 V, for 1.75 s.
Also der P0700 ist nur die Anforderung der MIL, wenn ich mich nicht täusche. Dein P1839 ist ein elektrisches Problem, also Kabel korridiert oder wirklich Öl drinnen. Kontrollier mal alles durch, hatte mal einen ähnlichen Fehler, bei mir war es jedoch ein Kabelbruch.
