NOTE
Be sure the battery is fully charged.
Main Harness [B] ESD Actuator [C]
Special Tool - Peak Voltage Adapter: 57001-1415 Type: KEK-54-9-B
ESD Actuator Input Voltage Connections to Adapter:
(I) Digital Meter (+) → BK (actuator BK) lead Digital Meter (–) → Battery (–) terminal (II) Digital Meter (+) → R (actuator R) lead Digital Meter (–) → Battery (–) terminal (III) Digital Meter (+) → W (actuator O) lead Digital Meter (–) → Battery (–) terminal (IV) Digital Meter (+) → Y (actuator Y) lead Digital Meter (–) → Battery (–) terminal
Input Voltage
Standard: About DC 9 11 V and then
0.1 V or
About DC 9 11 V
If the reading is out of the specification, remove the ESD ECU and check the wiring for continuity between main harness connector.
Special Tool - Hand Tester: 57001-1394
Disconnect the ESD ECU and actuator connectors.
Wiring Continuity Inspection ESD ECU Connector [A] ←→ ESD Actuator Connector [B] BK lead (ESD ECU terminal 3) [C] R lead (ESD ECU terminal 4) [D] O lead (ESD ECU terminal 12) [E] Y lead (ESD ECU terminal 13) [F]
If the wiring is good, check the ESD ECU for its ground and power supply (see ESD ECU Power Supply Inspection).
If the ground and power supply are good, replace the ESD ECU (see ESD (Electronic Steering Damper) ECU Removal/ Installation in the Steering chapter).

Steering Stem Warp Inspection
Whenever the steering stem is removed, or if the steering
can not be adjusted for smooth action, check the steering
stem for straightness.
If the steering stem [A] is bent, replace the steering stem.

Camshaft Runout Inspection
Remove the camshafts (see Camshaft Removal).
Set the camshaft in a camshaft alignment jig or on V
blocks.
Measure the runout with a dial gauge at the specified
place as shown in the figure.
If the runout exceeds the service limit, replace the
camshaft.
