Steering Angle Sensor Communication Stop Mode (07/2015 -): Procedure
- CHECK FOR OPEN IN CAN BUS LINES (STEERING SENSOR BRANCH LINE)
- Disconnect the cable from the negative (-) battery terminal.
- Disconnect the H23 steering sensor connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition H23-3 (CANH) - H23-2 (CANL) Cable disconnected from negative (-) battery terminal 54 to 69 Ω TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Steering Sensor)
Result: NG
NG
REPAIR OR REPLACE CAN BRANCH LINE OR CONNECTOR (STEERING SENSOR)
Result: OK
OK
See step 2
- CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition H23-1 (ESS) - Body ground Cable disconnected from negative (-) battery terminal Below 1 Ω TEXT IN ILLUSTRATION*a Front view of wire harness connector
(to Steering Sensor) - Reconnect the cable to the negative (-) battery terminal.
