(to Steering Angle Sensor)


Remove the steering wheel and column cover.


b.

Make sure that there is no looseness at the locking part and the connecting part of the connector.


c.

Disconnect the E115 steering angle sensor connector.


d.

Measure the voltage according to the value(s) in the table below.

Standard Voltage:
Tester Connection Condition Specified Condition
E115-5 (BAT) - Body ground Always 11 to 14 V
E115-4 (IG) - Body ground Engine switch on (IG) 11 to 14 V



Result:
Proceed to
OK
NG



OK

2.CHECK HARNESS AND CONNECTOR (GROUND TERMINAL)

Turn the engine switch off.


b.

Measure the resistance according to the value(s) in the table below.

NOTICE:

Before measuring the resistance of the steering angle sensor, turn the engine switch off and leave the vehicle for 1 minute or more without operating the key or switches, or opening or closing the doors.


Standard Resistance:
Tester Connection Condition Specified Condition
E115-1 (ESS) - Body ground 1 minute after turning engine switch off Below 1 Ω


Result:
Proceed to
OK
NG


HINT:

If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step before replacing parts.
