S7RS0B4604034
DTC Detecting Condition and Trouble Area
Step Action Yes No
1 Was “Electronic Stability Program Check” performed? Go to Step 2 Go to “Electronic
Stability Program
System Check”.
2 Check fuse
1) Check circuit fuses for steering angle sensor and its
circuit.
Is it good condition?
Go to Step 3. Replace fuse and check
for short circuit to
ground.
3 Check steering angle sensor power supply circuit
1) Turn ignition switch to OFF position.
2) Disconnect steering angle sensor connector.
3) Check for proper connection to steering angle sensor
connector terminals at “G50-1”, “G50-2” and “G50-3”.
4) If OK, then measure voltage between connector terminal
“G50-3” and vehicle body ground.
Is it 10 – 14 V?
Go to Step 4. “WHT/RED” wire circuit
open.
4 Check steering angle sensor power supply circuit
1) Measure voltage between connector terminal “G50-1”
and vehicle body ground with ignition switch turned ON.
Is it 10 – 14 V?
Go to Step 5. “GRN/ORN” wire circuit
open.
5 Check steering angle sensor ground circuit
1) Turn ignition switch to OFF position.
2) Measure resistance between connector terminal “G50-2”
and vehicle body ground.
Is resistance less than 2
Ω
?
Go to Step 6. “BLK/ORN” wire circuit
open or high resistance.
6 Check steering angle sensor
1) Connect steering angle sensor connector.
2) Check steering angle sensor referring to “Steering Angle
Sensor On-Vehicle Inspection”.
Is it good condition?
Substitute a known-
good ESP® hydraulic
unit / control module
assembly and recheck.
Substitute a known-
good steering angle
sensor and recheck.
DTC Detecting Condition Trouble Area
