2 minutes 10 seconds. Troubleshooting Common Keyread V20 Mitsubishi Errors Even with V20 magic, things can go wrong. Here are the three most common error codes and their fixes. Error 0xE4: "ECU Handshake Failed" Cause: The Keyread V20 cannot connect to the Immobilizer (IMMO) module. Fix: Check the OBD2 pins. Mitsubishi uses a non-standard CAN protocol on pins 1 and 9 (not the standard 6 and 14). A cheap OBD2 extension cable may interrupt this. Use the direct cable provided with the Keyread V20. Error 0x7B: "Invalid Transponder" Cause: You are using a transponder that is locked to another vehicle. Fix: While V20 can write to virgin chips, it cannot overwrite a locked 8D-70 chip. You must use a brand-new, "empty" 8D-70 (also known as ID70 or Megamos 8D). The Keyread V20 includes a "Transponder Tester" tool—use it to check the chip's status before inserting it into the ignition. Error 0x99: "Server Denied" Cause: Your Keyread V20 subscription has expired or you are trying to program a stolen vehicle flagged in the Mitsubishi database. Fix: Keyread V20 requires an annual subscription for cloud PIN decryption (approx. $150/year). If your subscription is active and the car is legally owned, contact Keyread support with your VIN; sometimes a regional server lock occurs.
