Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
Remove the LDWS switch. (See LDWS SWITCH REMOVAL/INSTALLATION .)
Measure the resistance between LDWS switches B and C under the following conditions:
- Resistance with LDWS switch pressed and held
  - 753.89-769.11 ohms
- Resistance with any switches not pressed
  - 1, 139.99-1, 163.01 ohms
