Toyota Corolla Repair Manual: Circuit description
When the brake pedal is depressed, the stop lamp switch assy sends a signal to the cruise control ecu assy.
When the cruise control ecu assy receives this signal, it cancels the cruise control.
A fail–safe function is provided so that cancel functions normally, even if there is a malfunction in the stop light switch circuit.
The cancel conditions are: battery positive voltage at terminal stp–.
When the brake pedal is depressed, normal battery positive voltage normally is applied through the stop fuse and stop lamp switch assy to terminal stp– of the cruise control ecu assy, and the cruise control ecu assy turns the cruise control to off.
If the harness connected to terminal stp– has an open circuit, terminal stp– will have battery positive voltage and the cruise control will be turned off.
Also, when the brake pedal is depressed, the magnetic clutch circuit is cut mechanically by the stop lamp switch assy, turning the cruise control off.

Overhaul
1. Inspect 1st gear thrust clearance
Using a feeler gauge, measure the 1st gear thrust clearance.
Standard clearance:
0.10 – 0.40 Mm (0.0039 – 0.0157 In.)
2. Inspect 2nd gear thrust clearance
Using a dial indicator, measure the 2nd gear thrust clearance.
Standard clearance:
...
On–vehicle inspection
1. Inspect w/receiver condenser assy
if a fin of the w/receiver condenser assy is dirty, clean it with
water and dry it with compressor air.
Notice:
do not damage the fin of the w/receiver condenser assy.
if a fin of the w/receiver condenser assy is bent, make it
straig ...
Capacity and distribution
Cargo capacity depends on the total weight of the occupants.
(Cargo capacity) = (Total load capacity) — (Total weight of occupants)
Steps for Determining Correct Load Limit —
(1) Locate the statement “The combined weight of occupants and cargo should never
exceed XXX kg or XXX lbs.” on your veh ...
