ON-VEHICLE INSPECTION
PROCEDURE
1. CONNECT TECHSTREAM
(a) Connect the Techstream to the DLC3 with the ignition switch off.
(b) Start the engine and run it at idle.
(c) Turn the Techstream on.
(d) Enter the following menus: Chassis / ABS/VSC/TRAC/EPB / Active Test.
HINT:
Refer to the Techstream operator's manual for further details.
2. INSPECT ACTUATOR MOTOR OPERATION
(a) Enter the following menus: Chassis / ABS/VSC/TRAC / Active Test / Motor Relay.
Chassis > ABS/VSC/TRAC > Active Test| Tester Display |
|---|
| Motor Relay |
(b) Turn the motor relay on and check for actuator motor operation sounds.
NOTICE:
Do not keep the motor relay on continuously for more than 5 seconds. If it needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
(c) Turn the motor relay off.
(d) Fully depress the brake pedal and hold it for approximately 15 seconds. Check that the initial brake pedal depth is maintained for the entire 15 seconds.
(e) Turn the motor relay on and check that the brake pedal does not pulsate.
NOTICE:
Do not keep the motor relay on continuously for more than 5 seconds. If it needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
(f) Turn the motor relay off and release the brake pedal.
3. INSPECT FRONT RIGHT WHEEL OPERATION
(a) Enter the following menus: Chassis / ABS/VSC/TRAC / Active Test / ABS Solenoid.
Chassis > ABS/VSC/TRAC > Active Test| Tester Display |
|---|
| ABS Solenoid |
(b) Depress the brake pedal and hold it.
NOTICE:
Do not turn on a solenoid in a manner different than that shown in the following steps.
(c) Turn the SFRH and SFRR solenoids on simultaneously and check that the brake pedal cannot be depressed further.
NOTICE:
Each solenoid operates for 2 seconds and turns off automatically. If a solenoid needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
(d) Turn the SFRH and SFRR solenoids off simultaneously and check that the brake pedal can be depressed.
(e) With the brake pedal still depressed, turn the motor relay on and check that the brake pedal rises.
Chassis > ABS/VSC/TRAC > Active Test| Tester Display |
|---|
| Motor Relay |
NOTICE:
Do not keep the motor relay on continuously for more than 5 seconds. If it needs to be operated repeatedly, wait an interval of more than 20 seconds between operations.
(f) Turn the motor relay off and release the brake pedal.
4. INSPECT OTHER WHEEL OPERATION
(a) Using the same procedure, check the solenoids for the other wheels.
HINT:
- Front left wheel: SFLH, SFLR
- Rear right wheel: SRRH, SRRR
- Rear left wheel: SRLH, SRLR

Starter Relay Circuit Short to Battery (P061512)
DESCRIPTION While the engine is being cranked, battery voltage is applied to terminal STA of the ECM. If the ECM detects the starter control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The ECM then illuminates the MIL and stores this
