CSLD Troubleshooting
SMPLS = Samples
TLCVOL = Temp. compensated volume
HEIGHT = Product height
AVGTEMP = Avg. fuel temperature
TOPTEMP = Temp. of the highest
thermistor in the probe
BDTEMP = Temp. of the probe circuit
board (in canister)
* following ACTIVE = Pump sense available

Tank Setup Check Before Troubleshooting

All in-tank setup data must be correct for CSLD to work properly. Setup data, such as manifolded status, pump
sense tank assignment, and temperature coefficient of thermal expansion entries, should be verified before
attempting troubleshooting procedures.

CSLD Alarms

Each of the three CSLD alarms, CSLD Rate Incr Warn, No CSLD Idle Time, and Periodic Leak Test Fail is
discussed below. In addition, there is one CSLD status message, No Results Available, which is also discussed.
