Definition
This message appears when the
KLN 94 fails a specific internal test
for the GPS receiver. The possible
error codes are described below:
ROM Failure: The ROM memory
has failed self-test.
RAM Failure: The RAM memory
has failed self-test.
Nonvolatile Memory Failure: The
battery-backed RAM has failed a
checksum test. Non-volatile
memory will be cleared.
RF Failure: This means the
receiver is not sensing a proper RF
signal from the satellites/antenna.
ASIC Failure: The GPS Correlator
ASIC fails self-test.
Suggested Action
Bad ROM. Return for service.
Bad RAM. Return for service.
It could be one of the following, in the order of
probability:
1. The battery-backup power to the GPS Receiver
was lost. This could be due to either a dead internal
battery or a bad connection on the cable to the
receiver.
2. The RAM memory is bad.
It could be one of the following, in the order of
probability:
1. Coax open or shorted. Confirm the 5 volts at the
antenna end.
2. Bad antenna. Substitute the antenna or inject a
signal at the coax.
3. Bad Receiver Module in GPS. Substitute the
GPS unit or inject signal at the input.
It could be one of the following, in the order of
probability:
1. The flex cable between the Receiver and Main
Board may have come out of the socket in the GPS.
2. Bad ASIC on receiver module in GPS. Substitute
the GPS unit.
