DESCRIPTION
The VGRS ECU drives the actuator based on the steering angle sensor signal and the vehicle speed signal.
If the VGRS ECU detects excessive current flowing into the actuator, or a malfunction inside the ECU, it turns on the warning light, records the DTC, and stops VGRS operation.

INSPECTION PROCEDURE
HINT:
Since only the actuator can be checked in this procedure, if it is normal, the VGRS ECU is faulty.
PROCEDURE
|
1.
|
INSPECT VGRS ACTUATOR FOR AN OPEN CIRCUIT
|
(a) Turn the ignition switch OFF.
(b) Disconnect the V13 actuator connector from the VGRS ECU.
|
(c) Measure the resistance of the actuator connector.
Standard resistance:
|
Tester Connection
|
Specified Condition
|
|
1 (BMV) - 5 (BMU)
|
0.1to 1 Ω
|
|
5 (BMU) - 6 (BMW)
|
|
|
|
(d) Check the continuity of the actuator connector and body ground.
|
|
OK:
|
Tester Connection
|
Specified Condition

|
1 (BMV) - Body ground
|
No Continuity
|
|
5 (BMU) - Body ground
|
|
