Kawasaki Ninja Service Manual: ESD Actuator Input Voltage Inspection

Kawasaki Ninja Service Manual / Self-Diagnosis System / ESD (Electronic Steering Damper) Actuator Error (Service Code E2E, ZX1000JD/KD) / ESD Actuator Input Voltage Inspection

NOTE

Be sure the battery is fully charged.

ESD Actuator Input Voltage Inspection

Turn the ignition switch to OFF.
Disconnect the ESD actuator connector and connect a suitable measuring leads [A] between these connectors as shown.

Main Harness [B] ESD Actuator [C]
Connect the peak voltage adapter [D] and a digital meter [E] to the measuring adapter leads.

Special Tool - Peak Voltage Adapter: 57001-1415 Type: KEK-54-9-B

ESD Actuator Input Voltage Inspection

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

Measure the actuator input voltage with the engine stopped and with the connector joined.
Turn the ignition switch to ON.

Input Voltage Standard: About DC 9 11 V and then
0.1 V or About DC 9 11 V

Turn the ignition switch to OFF.

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.
