DETEQ 81.01.1014 ERT45R Programming Kit for Bosch VP44 / VR30 Pumps
EAN: IP006604
Part Number (SKU): DETEQ 81.01.1014ERT45R programming kit for testing Bosch VP44 and VR30 electronically controlled rotary diesel injection pumps. Includes programming smartcard, 2 m basic cable, application adapter cable, illustrated servicing manual and access to available test data. Digitally synchronized testing requires the 81.01.1A01 Digital Pump Phasing System together with the appropriate VP44/VR30 pump-specific phasing/integration equipment. The ERT45R programming kit enables the ERT45R application; it does not program or flash the Bosch PSG pump control unit.

Bosch VP44 / VR30: digitally synchronized pump testing
Control the pump directly through its sensors and actuators, synchronize the injection event with cam position and verify timing dynamically.
VP44 and VR30 are electronically controlled rotary pumps with their own pump ECU. With the ERT45R method, testing is performed by connecting to the pump sensors and actuators required for the test rather than using the pump ECU as the test controller.
Not a governor-position application
Unlike electronically controlled VE or in-line pumps, VP44/VR30 testing is not based on positioning a governor. Injection control is synchronized with the angular position of the pump cam.
The injection event is controlled in two stages. ERT45R can operate one cylinder at a time or all cylinders together, allowing the technician to work directly with the injection-control behaviour of the pump.
CHECK BEFORE TESTING
Start with the pulse wheel
Reliable synchronization depends on a correct position signal. Before evaluating the rest of the pump, the pulse wheel should therefore be checked for contamination or physical damage.
If the complete tooth sequence cannot be recognized correctly, the pump cannot operate correctly. Verifying this signal first avoids treating a synchronization problem as an actuator, hydraulic or calibration fault.
Injection control, advance control and dynamic verification
Two-stage injection control
ERT45R controls the injection event according to cam position and can operate a single cylinder or all cylinders together.
Timing Control Valve
As a rotary pump, VP44/VR30 uses an advance piston. ERT45R controls the timing valve that acts on this mechanism.
Dynamic advance measurement
The resulting advance is measured dynamically, allowing commanded timing and the mechanical response of the pump to be verified together.
PUMP PHASING BEFORE TESTING
Establish the mechanical zero before controlling injection
On VP44 / VR30 pumps, injection control is referenced to cam position. Before the electronic test can be meaningful, the pump therefore has to be mechanically phased to a known angular reference.
The ERT45R method uses the 81.01.1A01 Digital Pump Phasing System as the universal angular-reference base, completed by the appropriate VP44 / VR30 pump-specific mechanical integration equipment.
The objective is to establish Zero Advance: the mechanical reference from which commanded injection timing and actual advance can subsequently be compared.
Mount and connect the pump
Install the VP44 / VR30 on the test bench using the appropriate mechanical integration components and connect the angular-reference system.
Find the Zero Advance position
Rotate and position the pump according to the VP / VR procedure until the mechanical Zero Advance reference is identified. This establishes the real starting point for timing measurements.
Set the angular reference
Once Zero Advance has been established, the electronic angular reader is referenced to that position. The 81.01.1A01 system then provides the angular position used by ERT45R during synchronized operation.
Verify synchronization dynamically
With the pump running, ERT45R correlates cam position, injection command and the action of the advance mechanism so that synchronization and effective timing can be checked dynamically.
Shared architecture with Denso ECD-V3 / V4 / V5
The principle is the same used by the ERT45R digital-pump architecture for Denso ECD applications: a universal angular-reference system provides the bench-side reference, while a pump-family integration kit adapts that system mechanically to the specific pump.
Phasing and dynamic advance are two different checks
Phasing establishes where the pump is mechanically positioned. Dynamic advance measurement verifies what the pump actually does after ERT45R commands the timing control valve during operation.

TEST THE PUMP WITHOUT TURNING EVERY TEST INTO AN ECU-PROGRAMMING JOB
ERT45R Programming Kit does not mean pump-ECU programming
These are two completely different operations.
The 81.01.1014 Programming Kit enables the ERT45R control unit with the functions required to test VP44 / VR30 pumps. It does not erase, flash or program the Bosch PSG pump control unit.
VP44 / VR30 pumps have their own electronic control unit. During the ERT45R test, that control unit is excluded from the test-control function: ERT45R connects directly to the sensors and actuators required to operate and evaluate the pump.
Bosch programming-based test workflow
The official procedure can require the program installed in the pump control unit to be removed, a standard test program to be installed for bench testing and the appropriate program to be restored after the test.
ERT45R functional test workflow
ERT45R operates the relevant pump sensors and actuators directly. When the PSG and its existing software are intact, functional pump testing therefore does not require ECU reprogramming to become a routine part of every test.
In workshop practice, actual PSG reprogramming is required in a relatively limited number of cases—for example when the control unit is physically damaged or its program has been erased. When programming really is required, it remains a separate proprietary Bosch operation.
Programming kit contents
The application layer for ERT45R, with the connection equipment and documentation required by the kit.
Programming smartcard
Enables the ERT45R functions required for VP44/VR30 testing.
2 m basic cable
Provides the common connection from the ERT45R control unit to the application-specific pump connection.
Adapter cable
Interfaces the ERT45R basic cable with the VP44/VR30 pump connection. Other connection variants can be handled with the appropriate adapter equipment where required.
