Diagnosis Procedure
1.Check connector
Is the inspection result normal? Yes >> go to 2.
No >> repair the terminal and connector
2.Check harness for open circuit

Is the measurement value within the specification? YES >> GO TO 3.
NO >> Repair the steering angle sensor branch line.
3.Check power supply and ground circuit
Check the power supply and the ground circuit of the steering angle sensor. Refer to brc-44, "wiring diagram".
Is the inspection result normal? Yes (present error)>>replace the steering angle sensor. Refer to brc-113, "removal and installation".
Yes (past error)>>error was detected in the steering angle sensor branch line.
No >> repair the power supply and the ground circuit.
