| Test | Work Order Description | Nominal Value |
| T01 | Check: Component | |
| This parameter is an internal value of the control unit. The INJECTION PULSE is a value calculated by the control unit and is influenced by various other parameters (e.g. coolant temperature, intake air temperature, manifold air pressure, idle speed stabilisation, etc.). The INJECTION PULSE cannot be adjusted by the mechanics. Check the following component for proper operation: Y32 Injection Valve - Fuel Y7 Injection Valves - Fuel Fuel pump pressure Fuel pressure regulator P33 Sensor - Oxygen, Exhaust P34 Potentiometer - Throttle Valve P23 Sensor - Absolute Pressure, Intake Manifold P29 Temperature Sensor - Intake Manifold Y18 Solenoid Valve - Exhaust Gas Recirculation | Test okay? |
| Yes: T02 | No: E03 |
| T02 | Check: Adjustment | |
| Are you using the latest version of control unit software? | System okay? |
| Yes: E01 | No: E02 |

| Result | Cause Of Fault |
| E01 | Following system/component is faulty: Leak in the exhaust system or Leak in the intake system or Leak in the injectors (dripping) or Engine-compression or Engine valve gear or Engine oil pressure or If programming/nominal value is okay and system is still faulty the following component is defective: K57 Control Unit - Multec |
| E02 | Perform service programming SPS to download the latest version of control unit software into the control unit. |
| E03 | Repair the concerned circuit/component. |
