ABOUT THE IMMOBILIZER DIAGNOSTIC MANUAL
The immobilizer diagnostic manual outlines the detailed procedures to troubleshoot complaints related to
the engine immobilizer system fitted on Mahindra Scorpio Vlx/Sle/Lx (Refresh) vehicles. Since the
engine immobilizer system is related to vehicle security, only authorized persons (CoTEKs) can work on the
immobilizer system in conjunction with M&M TEKline.
This manual covers –
• Procedures to be followed while reassigning old keys or assigning new keys to a vehicle.
• Procedures to be followed while replacing Engine Management System (EMS) ECU or Immobilizer
ECU (ICU).
• Retrieving DTCs from ECU and/or ICU, analyzing the complaint and taking corrective action.
In spite of our best efforts to make the manual error-free, a few errors could have inadvertently crept in. If
you identify errors, functional or typographical , please inform your
Suggestions to improve the manual and make it more user-friendly are also welcome.
