If Battery(supply) voltage greater than 16V
Alternator voltage o/p is greater than 14.5V.
Normal Operating Condition
Normal operation voltage range is 9V - 16V.
Normal operation means, that the sensors are
working, and the obstacle distance information is
sent out via CAN messages.
Operation voltage range for CAN communication
is 7V to 18V. Degraded CAN communication is
not allowed outside this range.
Probable Trouble Area
Vehicle electrical fault
Healing Condition
NA
Preliminary Checks:
1.
Voltage at the battery terminals should be greater than 16V
2.
Alternator output voltage should be between 13.5 V to 14.5 V in engine running
