SPN 132/FMI 1

This diagnosis is typically Air Mass Adaptation failed.‪

Note: Either of the following procedures (refer to "31.1.1 Air Mass Adaptation Using DDDL 7.0" or refer to "31.1.2 Air Mass Adaptation Manual Mode Using the Throttle Pedal" ) must be performed after the following components have been replaced.

  • MCM reprogrammed or replaced
  • Single-stage turbo
  • Dual-stage turbo (MBE 900 only)
  • Inlet Air Delta P Sensor
  • Systec Sensor (attached to turbo, hoses from Inlet Air Delta P are attached)
  • Intake Manifold Pressure/Temperature Sensor
  • Turbo Inlet Pressure/Temperature Sensor
  • Turbo Outlet Temp Sensor (MBE 900 only)
  • Turbo inlet elbow
  • Air inlet piping (FLC parts if part number has been revised)

Section 31.1.1
Air Mass Adaptation Using DDDL 7.0

Check as follows:‪

  1. Connect DDDL 7.0.
  2. Start the engine.
  3. Execute the Air Mass Adaptation Service routine.

Section 31.1.2
Air Mass Adaptation Manual Mode Using the Throttle Pedal

Check as follows:‪

Note: This procedure does NOT use DDDL 7.0.

  1. Start the engine.
  2. Monitor the engine coolant temperature until it reaches 40°C (104°F) for the MBE 900, 60°C (140°F) for the MBE 4000.
  3. Increase the rpm to 1700 (MBE 4000) or 1800 (MBE 900) and hold for 30 seconds.

    Note: If rpm can not be achieved due to engine limiter settings, the DDDL 7.0 Air Mass Adaptation Service routine must be used.

  4. Increase the rpm to 2200 ( MBE 900) or 2270 (MBE 4000) and hold for 30 seconds.
  5. Return to idle and the fault will be cleared.
