DESCRIPTION
Steering angle sensor (spiral cable with sensor sub-assembly) signals are sent to the skid control ECU (master cylinder solenoid) via the CAN communication system. When there is a malfunction in the CAN communication system, it is detected by the steering angle sensor zero point malfunction diagnostic function.

2. |
CHECK HARNESS AND CONNECTOR (IG, BAT TERMINAL) |
(a) Make sure that there is no looseness in the locking part and connecting part of the connectors.
(b) Disconnect the S32 steering angle sensor (spiral cable with sensor sub-assembly) connector.
(c) Measure the voltage according to the value(s) in the table below. Standard Voltage:
|
|
NG |
REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT) |

3. |
CHECK HARNESS AND CONNECTOR (ESS TERMINAL) |
(a) Turn the ignition switch off.
(b) Disconnect the S32 steering angle sensor (spiral cable with sensor sub-assembly) connector.
(c) Measure the resistance according to the value(s) in the table below. Standard Resistance:

Rear Speed Sensor RH Malfunction (C1403,C1404)
DESCRIPTION
The speed sensor detects wheel speed and sends the appropriate signals to the
skid control ECU (brake actuator assembly). These signals are used for brake control.
The speed sensor rotors have rows of alternating N and S magnetic poles and their
magnetic fields change when the roto ...

Rear Right Sensor Malfunction (C1AE9)
DESCRIPTION
The No. 1 ultrasonic sensor (rear corner sensor RH) is installed on the rear
bumper. The ECU detects obstacles based on signals received from the No. 1 ultrasonic
sensor (rear corner sensor RH). If the No. 1 ultrasonic sensor (rear corner sensor
RH) has an open circuit or other ma ...
