On–vehicle inspection
1. Inspect brake line pipes and hoses

Hint
: work in a well–lighted area. Turn the front wheels fully to the right or left before begining.
- check all the brake lines and hoses for:
- damage
- wear
- deformation
- cracks
- corrosion
- leaks
- bends
- twists
- check all the clamps for tightness and the connections for leakage.
- check that the hoses and lines are not near sharp edges, moving parts and the exhaust system.
- check that the lines are installed pass through the center of the grommets.
2. Inspect front brake pads and discs
3. Inspect rear brake linings and drums
4. Inspect or change brake fluid

Circuit description
The ecm compares the two waveforms of the heated oxygen sensors located
before and after the catalyst
to determine whether or not the catalyst performance has deteriorated.
Air–fuel ratio feedback compensation keeps the waveform of the heated oxygen
sensor in front of the catalyst

On–vehicle inspection
1. Check battery electrolyte level
Check the electrolyte quantity of each cell (maintenance–free battery).
If under the lower level, replace the battery (or add distilled
water if possible) and check the charging
system.

Circuit description
The vehicle speed sensor circuit is sent to cruise control ecu assy as a
vehicle speed signal. For each rotation
of the shaft, the vehicle speed sensor sends a signal through the combination
meter assembly to the
cruise control ecu assy (see the following chart). The cruise control ecu assy
