MSD • WWW.MSDPERFORMANCE.COM • (915) 855-7123 • FAX (915) 857-3344
1 Low Battery Voltage EngineRPM > 500 AND Vbatt < This alert activates when there is low battery voltage
9.0 for 5 seconds with engine RPM. Make sure the 7730/77303 is properly
connected to battery voltage.
2 High Battery Voltage Vbatt > 18.0 This alert activates when there is high battery voltage.
Make sure the 7730/77303 is properly connected to battery voltage
3 Crank Sensor This alert activates due to weak crank sensor signal. Make sure
the crank sensor is properly located according to the installation
instructions.
5 No CAM Sync Engine RPM > 300 AND This alert activates when individual cylinder timing has been
configured and no optical CAM sync signal is detected. Make
sure the optical CAM sync cable is properly connected to the
7730/77303.
6 12V Output Current > 3A for 10 ms This alert activates when there is too much load on
Shutdown the 12V bus that is used to power accessory modules. Make sure
there are no short circuits and the 12V bus is not overloaded.
13 Low SDcard Storage This alert activiates when an SDCard is present and there is
less than 100 MB of storage available on the card. Remove
some data from the SDCard to remove this alert.
14 SDcard Initialization This alert activates when the 7730/77303 cannot initialize the
SDCard. Make sure you are using the MSD factory supplied
SDCard.
15 SDcard Write Error This alert activates when the 7730/77303 is unable to write to
the SDCard. Make sure you are using the MSD factory supplied
SDCard.
16 SDcard Read Error This alert activates when the 7730/77303 is unable to read the
SDCard. Make sure you are using the MSD factory supplied
SDCard.
17 SDcard Missing SDcard not present AND data acquisition enabled AND Engine
is running.
18 Data Acquisition DAQ memory buffer overflow This alert activates if the interal data acquisition memory buffer
overflows. This will cause a recording to end prematurely. Try
deactivating some data acquisition channels. Make sure you
are using the MSD factory supplied SDCard.
19 12V Output Overcurrent Current > 2A for 10 ms This alert occurs when there is too much load on the 12V bus
that is used to power accessory modules. Make sure the 12V
bus is not overloaded.
20 EEPROM CRC Error This alert occurs if the 7730/77303 is unable to recover
configuration data from its internal EEPROM memory. The
7730/77303 will attempt to recover a back-up stored in its
internal Flash memory. Verify your configuration settings are
correct. If this error occurs frequently, contact MSD tech support
for an RMA.

21 EEPROM Write Error This alert occurs if the 7730/77303 is unable to write
data to its internal EEPROM memory. If this error occurs
frequently, contact MSD tech support.
22 Data Acquisition This alert activates if the internal data acquisition memory
buffer reaches a critical limit. This will cause some data
acquisition channels to be automatically disabled. Try
deactivating some data acquisition channels. Make sure
you are using the MSD factory supplied SDCard.
