P07D1Transmission Mode Switch E Circuit

  • Generic OBD-II code · Powertrain
How the car detects it
Transmission mode switches select alternative shift programs such as sport, winter or tow/haul; the J2012 family runs from A (P071A–P071C) and B (P071D–P071F) to C (base code P078F), D and E. No manufacturer document available to us uses switches C to E; GM reads its analog mode switch under its own codes (low below 21–29 % of 5 V, high from 94 %, two trips) and newer drive mode selectors under P05D0–P05D3. P07D1 is the general circuit fault of a fifth mode switch E: its state is invalid or implausible. Low and high are P07D2/P07D3.
