Step
Check
Yes
No
1
CHECK POWER SUPPLY FOR STEERING
ANGLE SENSOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from steering
angle sensor.
3) Turn the ignition switch to ON.
4) Measure the voltage between steering
angle sensor and chassis ground.
Connector & terminal
(B231) No. 4 (+) — Chassis ground (
−
):
Is the voltage 10 — 15 V?
Go to step 4.
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
steering angle
sensor and
VDCCM&H/U.
Go to step 3.
3
CHECK POOR CONTACT IN CONNECTORS. Is there poor contact in con-
nector?
Correct or replace
the connector.
Go to step 7.
4
CHECK GROUND CIRCUIT FOR STEERING
ANGLE SENSOR.
Measure the resistance between steering
angle sensor and chassis ground.
Connector & terminal
(B231) No. 3 — Chassis ground:
Is the resistance 0.5
Ω
?
Go to step 5.
Repair ground cir-
cuit in the steering
angle sensor.
5
CHECK STEERING ANGLE SENSOR.
1) Turn the ignition switch to OFF.
2) Connect all the connectors.
3) Erase the memory.
4) Perform the inspection mode.
5) Read the DTC.
Is the same DTC displayed?
Go to step 6.
Go to step 8.
6
CHECK VDCCM&H/U.
1) Turn the ignition switch to OFF.
2) Replace the steering angle sensor.
3) Erase the memory.
4) Perform the inspection mode.
5) Read the DTC.
Is the same DTC displayed?
Replace the
VDCCM&H/U.
<Ref. to VDC-7,
VDC Control Mod-
ule & Hydraulic
Control Unit
(VDCCM&H/U).>
Go to step 9.
7
CHECK STEERING ANGLE SENSOR.
1) Turn the ignition switch to OFF.
2) Connect all the connectors.
3) Erase the memory.
4) Perform the inspection mode.
5) Read the DTC.
Is the same DTC displayed?
Replace the
VDCCM&H/U.
<Ref. to VDC-7,
VDC Control Mod-
ule & Hydraulic
Control Unit
(VDCCM&H/U).>
Go to step 8.
8
CHECK OTHER DTC DETECTION.
Is any other DTC displayed?
Perform the diag-
nosis according to
DTC.
Temporary poor
contact occurs.
9
CHECK OTHER DTC DETECTION.
Is any other DTC displayed?
Perform the diag-
nosis according to
DTC.
Original steering
angle sensor mal-
function
