3.With the ignition switch turned to the "ON" position, read the voltage between terminals No.2 (G-sensor output) and 3 (G-sensor earth).
Standard value: 2.50 ± 0.15 V
4.With special tool test harness set (MB991348) connected, rotate so that the arrow mark straight down. Read output voltage between terminals No.2 (G-sensor output) and 3 (G-sensor earth).
Standard value: 3.50 ± 0.15 V
5.When the measured values in Step 3 and Step 4 are not within the standard value, measure the voltage between terminal No. 1 (sensor power supply) and terminal No. 3 (sensor earth).
Standard value: Battery voltage
6.If the measured values in step 3 and step 4 are out of the standard value and the measured value in step 5 is within the standard value, replace the G sensor.
7.When all the measured values in steps 3, 4 and 5 are out of the standard value, check the wiring harness and repair if necessary. When the wiring harness is normal, the ABS-ECU may be defective.
