Section 10 STEERING SYSTEM
Subsection 03 (OFF-THROTTLE ASSISTED STEERING (O.T.A.S.))
The procedure consists of manually pushing the
solenoid rod (which pulls the throttle cable and
activates the throttle plate) while reading the TPS
opening or resistance value depending on the tool
used.
Fully push the solenoid rod in and HOLD (simulat-
ing the electrical activation) while reading the val-
ue.

1. Push and HOLD solenoid rod
Use B.U.D.S. with the Vehicle Communication
Kit (VCK) (P/N 529 035 981) and look in Throttle
Opening under Monitoring tab.
Position and hold the mouse pointer over the nee-
dle of the throttle opening to get the actual value.
The value should be 17.3% +/-1. If not, adjust ca-
ble at solenoid bracket to get the value.

If B.U.D.S. is not available, resistance can be mea-

TPS.
Disconnect the AMP connector no. 4 from the
VCM.
Measure and note resistance between pins 4 and
11 of TPS wiring while at the idle position.
Push in solenoid rod and HOLD. Measure resis-
tance again.
Adjust cable at solenoid bracket to get an in-
creased resistance value of 165
