DESCRIPTION

WIRING DIAGRAM


INSPECTION PROCEDURE
1 CHECK STOP LIGHT SWITCH OPERATION
(a) Check that the stop light comes on when the brake pedal is depressed and goes off when the brake pedal is released.
OK 
HINT: Check the stop light bulb as it may have burnt out.


2 INSPECT SKID CONTROL ECU (STP1 TERMINAL)

(a) Disconnect the skid control ECU connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage 


3 RECONFIRM DTC
(a) Clear the DTCs (See page BC-82).
(b) Turn the ignition switch to the ON position.
(c) Are the same DTCs detected?
Result 
NOTICE: When replacing the brake actuator assembly, perform zero point calibration (See page BC-70).


REPLACE BRAKE ACTUATOR ASSEMBLY
4 INSPECT STOP LIGHT SWITCH

(a) Disconnect the stop light switch assembly connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance 


5 CHECK HARNESS AND CONNECTOR (STOP LIGHT SWITCH - SKID CONTROL ECU)

(a) Disconnect the stop light switch connector and skid control ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance 
NOTICE: When replacing the brake actuator assembly, perform zero point calibration (See page BC-70).

Solenoid Valve SL3)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear
position (1st, 2nd, 3rd, 4th
or 5th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory
to detect mechanical
troubles of the shift solenoid valves and valve bo ...
