Manufacturer Applications
NOTE 1: Limitation of engine output - read-out to indicate between 37 and 42mg/h for a
full throttle test in 3rd or 4th gear with an engine coolant min. temp of 80°C. This is
limitation based upon engine speed.
NOTE 2: Limitation of engine output - read-out to indicate between 35 and 45mg/h for a
full throttle test in 3rd or 4th gear with an engine coolant min. temp of 80°C. This is
limitation based upon measured inducted air quantity.
9 1. Engine speed.
2. Fuel quantity injected (with cruise control system active).
3. Fuel quantity limitation (with automatic gearbox, during gearshift).
4. Emergency fuel quantity injected (based on voltage signal from
modulating piston movement sender).
10 1. Quantity of air inducted.
2. Atmospheric (ambient) pressure.
3. Intake manifold (boost) pressure.
4. Accelerator pedal position.
11 1. Quantity of air inducted.
2. Atmospheric (ambient) pressure.
3. Intake manifold (boost) pressure.
4. Accelerator pedal position.
12 1. Not relevant.
2. Glow period (in seconds).
3. ECU supply voltage.
4. Coolant temperature.
13 1. Quantity injected - fuel variance (between cylinder 5 and cylinder 4, for
idle speed control).
2. Quantity injected - fuel variance (between cylinder 3 and cylinder 4, for
idle speed control).
3. Quantity injected - fuel variance (between cylinder 1 and cylinder 4, for
idle speed control).
4. Quantity injected - fuel variance (between cylinder 2 and cylinder 4, for
idle speed control).
14 1. Display Group 14 not been assigned.
15 1. Engine speed.
2. Quantity injected (actual).
3. Fuel consumption.
4. Desired quantity injected (controlled by driver depressing throttle).
