STEERING ANGLE SENSOR 5P CONNECTOR

SVCC (ORN)

8. Check for continuity between steering angle sensor

5P connector terminal No. 5 and body ground.

Repair short to body ground in the wire

between the steering angle sensor and the VSA
modulator-control unit.

Replace the VSA modulator-control unit

(see page 19-171).

1. Turn the ignition switch to ON (II).

2. Clear the DTC with the HDS.

3. Turn the ignition switch to LOCK (0), then turn it to

ON (II) again.

4. Check for DTCs with the HDS.

Go to step 5.

Intermittent failure, the system is OK at this

time. Check for loose terminals between the
steering angle sensor 5P connector and the VSA
modulator-control unit 37P connector. Refer to
intermittent failures troubleshooting (see page
19-98).

5. Turn the ignition switch to LOCK (0).

6. Disconnect the steering angle sensor 5P connector.

7. Disconnect the VSA modulator-control unit 37P

connector (see step 2 on page 19-171).

8. Check for continuity between VSA modulator-

control unit 37P connector terminal No. 7 and
steering angle sensor 5P connector terminal No. 5.

Go to step 9.

Repair open in the wire between the steering

angle sensor and the VSA modulator-control
unit.

9. Turn the ignition switch to ON (II).

10. Measure the voltage between steering angle

sensor 5P connector terminal No. 5 and body
ground.

Repair short to power in the wire between

the steering angle sensor and the VSA modulator-
control unit.

Check for loose terminals in the VSA

modulator-control unit 37P connector. If necessary,
substitute a known-good VSA modulator-control
unit (see page 19-171), and retest.

Wire side of female terminals

Is ther e continuity?

Is ther e 0.1 V or mor e?

DTC 65-21:

YES

Brake Fluid Level Stuck ON

NOTE: Bleeding the brake system while the ignition
switch is ON can cause this DTC.

1. Check the brake fluid level in the master cylinder

reservoir.

Go to step 2.

Do the brake pad inspection: Front (except

Type S model) (see page 19-12), front (Type S
model) (see page 19-15), rear (see page 19-29),
check for brake fluid leaks or replace worn brake
pads, then go to step 2, and recheck.

2. Turn the ignition switch to ON (II).

3. Clear the DTC with the HDS.

4. Turn the ignition switch to LOCK (0), then turn it to

ON (II) again.

5. Check for DTCs with the HDS.

Go to step 6.

Intermittent failure, the system is OK at this

time.

6. Release the parking brake.

7. Turn the ignition switch to LOCK (0), then turn it to

ON (II) again.

8. Check the brake system indicator in the gauge

control module (tach).

Check for loose terminals in the VSA

modulator-control unit 37P connector. If necessary,
substitute a known-good VSA modulator-control
unit (see page 19-171), and retest.

Go to step 9.

9. Check the BRAKE FLUID LEVEL SWITCH in the VSA

DATA LIST with the HDS.

Substitute a known-good gauge control

module (tach), then go to step 1, and recheck. If no
DTCs are indicated, replace the original gauge
control module (tach) (see page 22-277).

Go to step 10.

10. Disconnect the brake fluid level switch 2P

connector, then check the BRAKE FLUID LEVEL
SWITCH in the VSA DATA LIST.

Replace the brake master cylinder (the brake

fluid level switch is included) (see page 19-24).

Go to step 11.

11. Disconnect the gauge control module (tach) 36P

connector.

Is the br ake f luid level OK ?

Is DT C 65-21 indicated?

Does the indicator come on then go of f ?

Does the HDS indicate the BRAK E F LUID LEV EL
SW IT CH as OF F ?

Does the HDS indicate OF F ?

BRAKE FLUID LEVEL SWITCH 2P CONNECTOR

12. Check for continuity between brake fluid level

switch 2P connector terminal No. 2 and body
ground.

Repair short to body ground in the wire

between the gauge control module (tach) and the
brake fluid level switch.

Substitute a known-good gauge control

module (tach), then go to step 1, and recheck. If no
DTCs are indicated, replace the original gauge
control module (tach) (see page 22-277).

1. Turn the ignition switch to ON (II).

2. Clear the DTC with the HDS.

3. Turn the ignition switch to LOCK (0), then turn it to
