P1839 Fault Code: Understanding The Description And Troubleshooting Steps
The P1839 fault code refers to the Internal Mode Switch ‘C’ Circuit Low Voltage. This code is related to the Transmission Control Module (TCM) and indicates that the TCM has detected a voltage reading below 0.7V on the internal mode switch ‘C’ signal circuit for 1.75 seconds.
The internal mode switch is made up of five separate hall effect switches, each supplied with a 9V reference circuit and a signal circuit from the TCM.
These signal circuits provide voltage readings that indicate whether a particular gear selector position is on or off.
The voltage values on each internal mode switch circuit change depending on the position of the gear selector.
When the TCM detects a voltage below 0.7V on the internal mode switch ‘C’ signal circuit for a certain duration, it sets the P1839 fault code.
This code helps identify issues with the internal mode switch and allows for appropriate troubleshooting and repairs to be carried out.
FAQ
