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!

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:

Error Memory | 4
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

Error Memory | 4
Bosch Motorsport DDU 9 11/148
2 (at least one active error present in memory):
MIL blinking orange
Blinking orange border
Info cycling through
errors present in
error memory
4.2.2 Error Properties
The following channels are recognized and memorized inside the devices:
– Error type (device label “error_type_rotate”):
e.g. “below_threshold” for a violation of the minimum voltage range defined in the
configuration, “shortcut_Batt” for a shortcut to battery voltage etc.
– Error locations (device label “error_location_rotate”):
e.g. “ANA01” for an error concerning the first ANA channel
– Error durations
How long has the error been active? If an error encounters a non-active period before
being cleared from the memory and is then detected again, the error duration keeps
on accumulating. The number of active periods can be seen from the “number of oc-
currences”.
– Number of occurrences
How many times has the error been detected since the last time the error memory
was cleared.
– Error active state (device label “error_active_rotate”)
All failure modes are continuously diagnosed; any error detected will be written to the
error memory. Once an error is detected, it is qualified as “active”.
– 1 (TRUE) Error was detected in most recent diagnose run (active)

4 | Error Memory
12/148 DDU 9 Bosch Motorsport
– 0 (FALSE) Error is inactive: error was not detected in most recent diagnostic run,
however the error has not been cleared from the memory by the user and re-
mains in the non‐volatile memory
The aforementioned channels (error_active_rotate, error_location_rotate, error_type_ro-
tate) are device specific properties (e.g. C 60) and are not related to the complete Race-
Con project (e.g. “error no. 3 from the error memory”). Therefore, only one property label
is available in each device. The errors from the error memory (possibly more than one er-
ror possible per device) share these three labels. The labels cycle through the errors cur-
rently present in the memory and represent the respective property of each error period-
ically.
The following screenshot shows error properties, which can be displayed or logged:
Labels hold information
on error 1 (an ANA3 error)
Labels hold information
on error 2 ... n-1
Labels hold information
on error n (a CAN error)
After the last error and its error properties have been displayed, the labels will start again
with the first error in the error memory stack and its error properties will be displayed
again. Therefore, monitoring these labels over a sufficiently long period provides the in-
formation on all individual errors in the error memory.
To understand this behavior, it is recommended to observe the three labels in a measure-
ment sheet (while more than one error is active) and watch the values change periodically:
The verbal representation of the numerical codes of these labels can be visualized in the
properties window of the measurement page:

4.3 Analog Input Diagnosis
4.3.1 Monitoring limits / Shortcut Detection / Cable
Breakage
The pin diagnosis functionality (check whether measurement is within the desired range)
can be activated in the ANA pin setup wizard; to allow for a diagnosis regarding shortcut
to ground, shortcut to battery voltage and cable breakage, a minimum / maximum has to
be defined.

4 | Error Memory
14/148 DDU 9 Bosch Motorsport
4.3.2 Open Line Detection
The implementation of open line detection consists of pull up resistors being activated
and deactivated; evaluating the behavior of the measured value detects cable breakage,
regardless of the pull up resistor being activated by the user.
1. Open the Error Memory of the Device.
2. Click "start detection of cable".
3. Check the Error Memory for new fault entries, regarding "Open line errors".
