Kawasaki Ninja Service Manual: ESD (Electronic Steering Damper) ECU Error (Service Code E3b, ZX1000JD/KD)

Kawasaki Ninja Service Manual / Self-Diagnosis System / ESD (Electronic Steering Damper) ECU Error (Service Code E3b, ZX1000JD/KD)

If this service code appears, check that the following parts are correctly.

Crankshaft Sensor Gear Position Switch Starter Lockout Switch Main Throttle Sensor Rear Wheel Rotation Sensor

If these parts are normal, check the ESD ECU for its ground and power supply (see ESD ECU Power Supply Inspection).

ESD ECU Removal

ESD ECU Installation

Refer to the ESD (Electronic Steering Damper) ECU Installation in the Steering chapter.

ESD ECU Power Supply Inspection


ESD ECU Grounding Inspection Connections: (I) BK/Y lead (ESD ECU terminal 9) ←→ Battery (–) Terminal (II) Engine Ground ←→ Battery (–) Terminal Criteria: Both: 0 Ω

If no continuity, check the connector, the engine ground lead, or main harness, and repair or replace them if necessary.

If the wiring is good, check the power source voltage of the ESD ECU.

NOTE

Be sure the battery is fully charged.
