2 Preparation
Use the DDU 9 only as intended in this manual. Any maintenance or repair must be per-
formed by authorized and qualified personnel approved by Bosch Motorsport.
Operation of the DDU 9 is only certified with the combinations and accessories that are
specified in this manual. The use of variant combinations, accessories, and other devices
outside the scope of this manual are only permitted when they have been determined to
be compliant from a performance and safety standpoint by a representative from Bosch
Motorsport.
Read the manual carefully and follow the application hints step by step. Do not hesitate to
contact us, contact data can be found on the last page of this document.
Disclaimer
Due to continuous enhancements, we reserve the rights to change any illustrations, pho-
tos and technical data within this manual.
Please retain this manual for your records.
NOTICE
In this document, all screenshots are created by way of example for a
display. Please consider this and replace the product names with the
name of your device.

3 Power Supply
Please ensure that you have a good ground installation. That means:
– A ground that has a solid, low resistance connection to the negative battery terminal
– Connection should be free from dirt, grease, paint, anodizing, etc.
– Use large diameter wire
– More metal-to-metal contact is better!
The following notations for power signals are used:
– KL 15 is a switched battery rail controlled by the IGN-switch
– KL 30 is an unswitched battery positive rail (same as battery positive terminal)
– KL 31 is an unswitched ground rail (same as battery negative terminal)
Be careful to observe current limits of wires and connector pins!

4 Error Memory
In this chapter “Error Memory”, a lot of screenshots are created by way of example for
DDU 8. Please consider this and replace the product name ‘DDU 8’ in this case with the
name of your product.
4.1 Error memory representation in RaceCon
Bosch Motorsport devices feature an error memory. Information on errors can be visual-
ized via RaceCon (online measurement) or can be transmitted via telemetry.
4.1.1 Accessing the memory
The error memory can be accessed as shown in the illustration:
4 | Error Memory
8/148 DDU 9 Bosch Motorsport
The memory is situated inside the device and is non‐volatile. As a consequence, an error
which has occurred and has not been cleared by the user will remain in the error memory
even after a power cycle. The error state will then reflect if the error is still active or not.
An error is deleted from the list when
– the user actively clears the error memory
– the user updates the firmware
The error memory is not cleared by a configuration download and is not cleared by a
power cycle.
4.1.2 Clearing the error memory
There are two ways of clearing the error memory, both are shown in the following illustra-
tion:

Bosch Motorsport DDU 9 9/148
4.2 Information on errors available from the
error memory
In general, properties of the error memory and properties of an individual error need to
be distinguished.
4.2.1 Error Memory Properties
The following property is available for the error memory itself:
– Error Status (device measurement label “error_state”)
0: no error present in memory
1: at least one inactive error present in memory, no active errors
2: at least one active error present in memory
If displayed in a measurement sheet, this property’s value (0, 1 or 2) is translated into a
verbal description:
4 | Error Memory
10/148 DDU 9 Bosch Motorsport
It is also represented by a color scheme within RaceCon (provided RaceCon is online with
the system):
0 (no error present in memory):
No orange border
MIL off (black)
No entries
1 (at least one inactive error present in memory, no active errors):
Constantly orange border
Info cycling through
errors, present in
error memory
MIL constantly orange
