CAUTION / NOTICE / HINT
NOTICE:
Inspect the fuses for circuits related to this system before performing the following procedure.
PROCEDURE
|
1. |
CHECK HARNESS AND CONNECTOR (POWER SOURCE TERMINAL) |
|
(a) 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.
OK:
The connector is securely connected.
(c) Disconnect the G48 steering angle sensor connector.
(d) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(e) Measure the voltage according to the value(s) in the table below.
Standard Voltage:

|
|
2. |
CHECK HARNESS AND CONNECTOR (GND TERMINAL) |
|
(a) Turn the power 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 power 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:
|
