VEHICLE DYNAMICS CONTROL (VDC) (DIAGNOSTICS)

Diagnostic Procedure with Diagnostic Trouble Code (DTC)

Step

Check

Yes

No

1

CHECK POWER SUPPLY FOR YAW RATE &
LATERAL G SENSOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from yaw rate &
lateral G sensor.
3) Turn the ignition switch to ON.
4) Measure the voltage between yaw rate &
lateral G sensor and chassis ground.

Connector & terminal

(B230) No. 3 (+) — Chassis ground (

−

):

Is the voltage 10 — 15 V?

Go to step 3.

Go to step 2.

2

CHECK OUTPUT VOLTAGE OF VDCCM&H/
U.
Measure the voltage between VDCCM&H/U
and chassis ground.

Connector & terminal

(B310) No. 30 (+) — Chassis ground (

−

):

Is the voltage 10 — 15 V?

Repair the har-
ness between yaw
rate & lateral G
sensor and
VDCCM&H/U.

Go to step 5.

3

CHECK GROUND CIRCUIT OF YAW RATE &
LATERAL G SENSOR.
Measure the resistance between yaw rate &
lateral G sensor and chassis ground.

Connector & terminal

(B230) No. 6 — Chassis ground:

Is the resistance less than 0.5

Ω

?

Go to step 6.

Go to step 4.

4

CHECK GROUND CIRCUIT FOR VDCCM&H/
U.
Measure the resistance between VDCCM&H/U
and chassis ground.

Connector & terminal

(B310) No. 16 — Chassis ground:

Is the resistance less than 0.5

Ω

?

Repair the har-
ness between yaw
rate & lateral G
sensor and
VDCCM&H/U.

Go to step 5.

5

CHECK POOR CONTACT IN CONNECTORS. Is there poor contact in con-

nector?

Correct or replace
the connector.

Go to step 9.

6

CHECK HARNESS OF YAW RATE & LATER-
AL G SENSOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from VDCCM&H/
U.
3) Measure the resistance between
VDCCM&H/U and yaw rate & lateral G sensor.

Connector & terminal

(B310) No. 1 — (B230) No. 1:

Is the resistance less than 0.5

Ω

?

Go to step 7.

Repair the har-
ness between yaw
rate & lateral G
sensor and
VDCCM&H/U.

7

CHECK GROUND SHORT CIRCUIT OF HAR-
NESS.
Measure the resistance between VDCCM&H/U
and chassis ground.

Connector & terminal

(B310) No. 1 — Chassis ground:

Is the resistance more than 1
M

Ω

?

Go to step 8.

Repair the har-
ness between yaw
rate & lateral G
sensor and
VDCCM&H/U.

8

CHECK THE YAW RATE & LATERAL G SEN-
SOR.
1) Turn the ignition switch to OFF.
2) Install the yaw rate & lateral G sensor to
body.
3) Connect all the connectors.
4) Turn the ignition switch to ON.
5) Measure the voltage between VDCCM&H/
U connector terminals.

Connector & terminal

(B310) No. 1 (+) — No. 16 (

−

):

Is the voltage 2.1 — 2.9 V?

Go to step 9.

Replace the yaw
rate & lateral G
sensor. <Ref. to
VDC-14, Yaw Rate
& Lateral G Sen-
sor.>
