STEP 4. Check the solenoid valve
(1) Disconnect HBB connector B-14 and B-18, and measure at
the HBB side.
(2) Measure the resistance between the following solenoid
valve terminals.
• Control solenoid valve IN (FR): Between HBB connector
B-14 terminal 19 and HBB connector B-18 terminal 34
• Control solenoid valve OUT (FR): Between HBB con-
nector B-14 terminal 20 and HBB connector B-18 termi-
nal 34
• Control solenoid valve IN (FL): Between HBB connector
B-14 terminal 21 and HBB connector B-18 terminal 34
• Control solenoid valve OUT (FL): Between HBB connec-
tor B-14 terminal 22 and HBB connector B-18 terminal
34
• Control solenoid valve IN (RR): Between HBB connector
B-14 terminal 15 and HBB connector B-18 terminal 34
• Control solenoid valve OUT (RR): Between HBB con-
nector B-14 terminal 16 and HBB connector B-18 termi-
nal 34
• Control solenoid valve IN (RL): Between HBB connector
B-14 terminal 13 and HBB connector B-18 terminal 34
• Control solenoid valve OUT (RL): Between HBB con-
nector B-14 terminal 14 and HBB connector B-18 termi-
nal 34
• Select solenoid valve (FR): Between HBB connector B-
14 terminal 18 and HBB connector B-18 terminal 34
• Select solenoid valve (FL): Between HBB connector B-
14 terminal 17 and HBB connector B-18 terminal 34
Standard value: Control solenoid valve IN: 4.75
−
5.25
Ω
Control solenoid valve OUT: 2.0
− 2.4 Ω
Select solenoid valve: 3.5
− 3.9 Ω
Q: Is the resistance value within the standard value?
YES : Replace the M-ASTC-ECU and go to Step 5.
NO : Replace the HBB master cylinder and hydraulic unit
assembly. Then go to Step 5.
STEP 5. Recheck for diagnostic trouble code.
Q: Do DTCs 41, 42, 43, 44, 45 and 46 reset?
YES : Go to Step 1.
NO : The procedure is complete.
