| 11 | Ambient pressure = mbar | Atmospheric pressure, normal value is approximately 1000 mbar at sea level. The value varies depending on other circumstances. |
| 12 | Injection time = ms | Injector opening time. The normal value is approximately 2 ms when the engine is idling at operating temperature. |
| 13 | Lambda adaptation, part load = % | The value indicates how much the injection period at part load has been adjusted compared to a reference value. The value is first updated after the engine has been revved up. |
| 14 | Lambda adaptation, idle = ms | The value indicates how much the injection period at idling speed has been adjusted compared to a reference value. The value is first updated after the engine has been revved up. |
| 15 | Ignition angle = ° | Measurement range 72° before top dead center (TDC) to 23° after top dead center (TDC). Normal value when idling is approximately 0-15°. |
| 16 | Lambda status | O/L= Open Loop, fuel trim not active C/L= Closed Loop, fuel trim active |

| 18 | Oxygen sensor front signal (Lambda) = V | Voltage from the front heated oxygen sensor (HO2S). Measurement range 0 -1 V. Oscillates between 0 and 1 V when fuel trim is activated. |
| 19 | Oxygen sensor signal, rear = V | Voltage from the rear heated oxygen sensor (HO2S). Measurement range 0 -1 V. Oscillates between 0 and 1 V when the three-way catalytic converter (TWC) is cold (>300 °C). Stabilizes at 0.2-0.7 V when the three-way catalytic converter (TWC) is at operating temperature (<300 °C) |
| 20 | Idle duty cycle = % | Idle air control (IAC) valve opening. Measurement range 0 - 100%. The normal value is approximately 20-40% when idling with the engine at operating temperature. |
| 21 | Idle air trim adaptation = % | The value shows by how much idle air control (IAC) valve opening has been adjusted in relation to a predetermined value. Measurement range -50 to +50%. |
| 22 | Idle adaptation, A/C = % | Idle air trim adaptation with the A/C compressor activated. The value shows by how much idle air control (IAC) valve opening has been adjusted in relation to a reference value. |
| 23 | Turbo control valve duty cycle = % | Turbocharger (TC) control valve opening. Measurement range 0 - 100%. A value over 0% means the engine power is regulated using the valve. The value only applies when the turbocharger control valve is activated. |
| 24 | EVAP duty cycle = % | EVAP valve opening. Measurement range 0-100%. 0% EVAP valve shut. 100% EVAP valve fully open. The intermediate values depend on the opening of the EVAP valve |
| 25 | A/C-pressure = mbar | Pressure in the air conditioning (A/C) system. Measurement range 0 - 3442 mbar. |
| 26 | A/C demand = | Displays whether the engine control module (ECM) has requested that the ECC control module starts the air conditioning (A/C) compressor. The A/C-compressor is permitted to start if the air conditioning (A/C) pressure is below a parameter. Yes = ECC requests that the A/C compressor starts. No = ECC does not request that the A/C compressor starts. |
| 27 | A/C relay | Yes = A/C relay activated. No = A/C relay not activated. |
| 28 | Immo locked = | NO = Immobilizer control module permits start. Yes = Immobilizer control module does not permit start. |
| 29 | VIN learned = | Yes = Engine control module (ECM) has learned the VIN-code. No = Engine control module (ECM) has not learned any VIN-code. |
| 30 | Faulty VIN = | Yes = Different VIN codes in the immobilizer control module and engine control module (ECM). No = Immobilizer control module and engine control module (ECM) have the same VIN-code. The parameter is relevant only when the communication between the immobilizer control module and the engine control module (ECM) is functioning. |
| 31 | Manifold pressure = hPa | The pressure in the intake system. Measurement range 0 -2400 mbar. Normal value when idling is approximately 400 mbar. |
