STEP 3. Check M-ASTC-ECU connector E-119.
Q: Is M-ASTC-ECU connector E-119 in good condition?

YES : Go to Step 5.
NO :  Repair or replace the connector, and then go to Step 

6.

STEP 4. Check the wiring harness between HBB connector 
B-14 terminal 6 or 5 and M-ASTC-ECU connector E-119 
terminal 12 or 11.
When DTC 47 is set:

• M-ASTC-ECU connector E-119 terminal 6 and HBB con-

nector B-14 terminal 12

When DTC 48 is set:

• M-ASTC-ECU connector E-119 terminal 5 and HBB con-

nector B-14 terminal 11

Q: Is the wiring harness between HBB connector B-14 

terminal 6 or 5 and M-ASTC-ECU connector E-119 
terminal 12 or 11 in good condition?
YES : Go to Step 5.
NO :  Repair the wiring harness, and then go to Step 6.

STEP 5. Check the solenoid valve for continuity. Measure 
at HBB connectors B-14 and B-18.
(1) Disconnect HBB connectors B-14 and B-18, and measure 

the resistance at the component-side connector.

(2) Measure the resistance between the following terminals.

When DTC 47 is set:

• Measure the resistance between HBB connector B-14 

terminal 12 and HBB connector B-18 terminal 34.

• Select solenoid valve: 3.5 − 3.9 ohms

When DTC 48 is set:

• Measure the resistance between HBB connector B-14 

terminal 11 and HBB connector B-18 terminal 34.

• Select solenoid valve: 3.5 − 3.9 ohms

Q: Is the solenoid valve normal?

YES : Replace the M-ASTC-ECU, and then go to Step 6.
NO :  Replace the HBB master cylinder and hydraulic unit 

assembly, and then go to STEP 6.
