The evaporative emission system is designed to prevent the escape of fuel vapors from the fuel
system. Leaks in the system, even small ones, can allow fuel vapors to escape into the
atmosphere. Government regulations require onboard Testing to make sure that the evaporative
(EVAP) system is functioning properly. The leak detection system tests for EVAP system leaks
and blockage. It also performs self-diagnostics. During self-diagnostics, the Powertrain Control
Module (PCM) first checks the Leak Detection Pump (LDP) for electrical and mechanical faults.
If the first checks pass, the PCM then uses the LDP to seal the vent valve and pump air into the
system to pressurize it. If a leak is present, the PCM will continue pumping the LDP to replace
the air that leaks out. The PCM determines the size of the leak based on how fast/long it must
pump the LDP as it tries to maintain pressure in the system.

The ATS Co-Pilot module commands the lock-up clutch of the torque converter along with the exhaust brake, if equipped, to stay engaged. This allows for up to 100% of the retarding force to be transferred in 3rd and 4th gear and the transmission oil temperature to remain low because of little to no slippage occurring when the converter is in these selected gears. When the ATS Valve Body is installed, you can use engine braking in the low-speed position of nearly 12 mph in 1st or 2nd gear.

The L5 PCM is a supplemental lithium ion battery installed in the spare tire well of your Toyota Prius as shown in Figure 2. The L5 PCM provides approximately 5 kilowatt hours (kWh) of onboard electrical storage capacity. This additional electrical energy enables the Prius to use pure electric drive more often and for longer distances, resulting in fuel efficiency gains and CO2 emissions reduction over the standard Prius. The L5 PCM must be recharged from an electrical outlet or extension cord equipped with GFCI. The L5 PCM does not receive any regenerative charge during driving. When the L5 PCM is charged, the Prius is capable of achieving fuel economy in excess of 100 miles per gallon (mpg) and reducing CO2 emissions by up to 2/3rds over the standard Prius.
