STEP 14. Voltage measurement: A-05 ASC-ECU
connector

(1) Disconnect the connector, connect the ABS

check harness (Special tool: MB991984) to the
ASC-ECU side connector and harness-side
connector, and then measure the voltage at the
special tool connector side.

(2) Ignition switch: ON
(3) Measure the voltage between the power supply

and signal terminals in the wheel speed sensor
circuit and body earth.

OK:

<Power supply terminal> Approximately 12

V

<Signal terminal> 0.4 to 1.3 V

Q: Is the check result normal?

YES :

Go to Step 24.

NO (Not normal at the terminal No. 29 or 28) :

Go

to Step 15.

NO (Not normal at the terminal No. 34 or 13) :

Go

to Step 17.

NO (Not normal at the terminal No. 30 or 8) :

Go to

Step 19.

NO (Not normal at the terminal No. 11 or 10) :

Go

to Step 21.

STEP 15. Connector check: A-05 ASC-ECU
connector, A-29 wheel speed sensor <FR>
connector

Q: Is the check result normal?

YES :

Go to Step 16.

NO :

Repair the damaged connector.
