TROUBLESHOOTING

ACTIVE STABILITY CONTROL SYSTEM (ASC)

35C-15

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.
