LS 460 AWD V8-4.6L (1UR-FSE) (2009)
If incorrect, troubleshoot the brake system See: Testing and Inspection.
(e) Check the RL system solenoid (SLARL Solenoid Current, SLRRL Solenoid Current, Electronically Controlled Brake System Solenoid
(SMC1), Electronically Controlled Brake System Solenoid (SMC2)).
-
Select "SLARL Solenoid Current". Press "->" and check the output voltage.
NOTE:
Do not depress the brake pedal.
HINT: It takes approximately 35 seconds to complete the check.
Standard voltage:
If incorrect, troubleshoot the brake system See: Testing and Inspection.
(f) Check the changeover solenoid valves (SMC1, SMC2).
(1) Select and enter "Electronically Controlled Brake system Invalid" to prohibit the brake control.
(2) Check that the brake control warning light comes on.
(3) Check the output voltage by depressing the pedal.
Standard voltage:
Difference in output voltage between "MAS CYL PRESS 1" and "FR W/C SENS" is less than 0.4 V.
Difference in output voltage between "MAS CYL PRESS 2" and "FL W/C SENS" is less than 0.4 V.
(4) Press the return key on the Techstream and cancel brake control prohibition (ELECTRONICALLY CONTROLLED BRAKE SYSTEM
INVALID).
2. CHECK PRESSURE SENSOR OPERATION
(a) Check the battery voltage.
Standard voltage:
11 to 14 V (during engine stop)
(b) Connect the hydro booster pressure gauge and pedal effort gauge.
