INSPECTION PROCEDURE
HINT:
Start the inspection from step 1 in case of using the hand-held tester and start from step 2 in case of not
using the hand-held tester.
1 Check output value of the steering angle sensor.
PREPARATION:
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand-held tester main switch ON.
(c) Select the DATALIST mode on the hand-held tester.
CHECK:
Check that the steering wheel turning angle value of the steering angle position sensor displayed on the
hand-held tester is changing when turning the steering wheel.
HINT:
After certifying ºZeroº point calibration of the steering angle sensor (Speed: 21 mph (35 km/h), driving straight
ahead for 10 sec. or more), the value will change.
OK:
Steering wheel turning angle value must be changing.
OK Go to step 5.
NG
2 Check input voltage of the steering angle sensor.
PREPARATION:
Remove the column lower cover.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure voltage between terminals 1 and 2, 2 and 9 of
the combination switch wire harness side connector.
OK:
Voltage: 10 to 14 V
NG Check and replace harness and connector.
OK

DTC C1232 / 32 Deceleration Sensor Circuit
CIRCUIT DESCRIPTION
DTC No.DTC Detecting ConditionTrouble Area
C1232 / 32
Detection of either of the conditions 1. or 2.:
1. At a vehicle speed of 6 mph (10 km/h) or more, when
the condition that ECU terminal GL1 signal change
range is less than 20 mV, and ECU terminal GL2 signal
change range swings by 468 mV or more occurs for 30
sec. or more.
2. At a vehicle speed of 6 mph (10 km/h) or more, when
the condition that ECU terminal GL2 signal change
range is less than 20 mV, and ECU terminal GL1 signal
change range swings by 468 mV or more occurs for 30
sec. or more.

Deceleration sensor circuit
INSPECTION PROCEDURE
HINT:
Start the inspection from step 1 in case of using the hand-held tester and start from step 2 in case of not
using the hand-held tester.
1 Check output value of the yaw rate (deceleration) sensor.
PREPARATION:
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand-held tester main switch ON.
(c) Select the DATALIST mode on the hand-held tester.
CHECK:
Check that the deceleration value of the deceleration sensor displayed on the hand-held tester is changing
when tilting the vehicle.
OK:
Deceleration value must be changing.
OK Check and replace ABS & BA & TRAC & VSC
ECU.

3 Check output value of the yaw rate sensor.
In case of using the hand-held tester:
PREPARATION:
(a) Remove the 2 bolts and yaw rate sensor with connectors
still connected.
(b) Connect the hand-held tester to the DLC3.
(c) Turn the ignition switch ON and push the hand-held tes-
ter main switch ON.
(d) Select the DATALIST mode on the hand-held tester.
CHECK:
Check that the yaw rate value of the yaw rate sensor displayed
on the hand-held tester changes. Place the yaw rate sensor
vertically to the ground and turn the sensor pivoted on its center.
OK:
Yaw rate value must be changing.
In case of not using the hand-held tester:
PREPARATION:
(a) Remove the yaw rate sensor with the connector still con-
nected to it.
(b) Turn the ignition switch to ON.
CHECK:
Measure voltage between terminals YAW2 (1) - GYAW (5), and
terminals YD (6) - GYAW (5) of the yaw rate sensor.
OK:
Terminals 1 and 5
(YAW2 - GYAW)About 2.42 V to 2.58 V
Terminals 6 and 5
(YD - GYAW)About 4.5 V to 5.3 V
NG Replace yaw rate sensor.
