3. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   2 (BSV) - 4 (BSG)	Always	3 to 10 kΩ
   2 (BSV) - 3 (BSC)	Always	Below 0.5 kΩ
   3 (BSC) - 4 (BSG)	Always	3 to 10 kΩ
   1 (BST) - 4 (BSG)	Always	1.5 to 2.5 kΩ

NG → REPLACE ACTIVE STABILIZER BATTERY CURRENT SENSOR 

OK: Go to next step 

1. Disconnect the z8 rear active stabilizer control ECU connector.
2. Disconnect the E active stabilizer battery current sensor connector.
