UNIVERSAL · DTC LOOKUP

Crank-no-startEngine cranks normally but won't start

Universal diagnostic code. Below: what it means, common causes, symptoms, and the exact bench-programming fix path.

Common causes

  • Immobilizer authentication failing
  • Module degradation
  • Component protection / coding mismatch
  • Damaged cluster blocking IMMO chain

Symptoms you'll see

  • Healthy crank, no fire
  • Sometimes starts briefly then dies
  • Intermittent — gets worse over time

The fix path

Identify the specific module + chassis, then ship to AML for bench programming. Brand-specific routes: BMW → EWS/CAS/FEM. Mercedes → EIS. VW/Audi → IMMO delete. Land Rover → KVM/RFA.
