TD5, also known as Thunder which is mated to the Storm 5 cylinder diesel engine fitted in Defenders and Discovery series IIs.
It has a fault memory which can be read and cleared. It also gives a range of dynamic information values which are:
In the fueling section:
- Fuel, coolant and ambient air temperatures.
- Manifold and ambient pressures.
- Current air flow.
- Throttle potentiometer output and supply voltages.
- Duty ratios for the EGR modulator.
- EGR inlet throttle and turbocharger waste gate solenoids.
- The idle speed correction.
- Battery voltage.
- Road speed.
- Engine speed and balancing corrections for each cylinder.
In the switches section:
- Both brake switches.
- Air conditioning clutch request and output drive.
- Cooling fan request and drive.
- Gearbox inputs for currently selected gear and transfer box ratio.
- Clutch pedal switch and all three cruise control switches.
It has the ability for a selection of ECU outputs to be driven and has a large number of programmed in vehicle and market options and fuel map usage information which is changeable. Injector grading/coding can also be read and changed. Security mobilization learning and status checking is also catered for and the ECU can perform self tests of its outputs. The TD5 software module has been fully developed and tested and is available for inclusion on the ROVACOM LITE system.
