2. CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect low tire pressure warning control unit connector.
2. Check resistance between low tire pressure warning control unit
harness connector terminals.
OK or NG
OK >> Replace low tire pressure warning control unit.
NG >> Repair harness between low tire pressure warning con-
trol unit and data link connector.
Steering Angle Sensor Circuit InspectionNKS003Y8
1. CHECK CONNECTOR
1. Turn ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check terminals and connector of steering angle sensor for damage, bend and loose connection (sensor
side and harness side).
OK or NG
OK >> GO TO 2.
NG >> Repair terminal or connector.
2. CHECK HARNESS FOR OPEN CIRCUIT
1. Disconnect steering angle sensor connector.
2. Check resistance between steering angle sensor harness con-
nector terminals.
OK or NG
OK >> Replace steering angle sensor.
NG >> Repair harness between steering angle sensor and data
link connector.
Intelligent Key Unit Circuit InspectionNKS003Y9
1. CHECK CONNECTOR
