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 Power Supply Inspection


If the connector is clogged with mud or dust, blow it off with compressed air.

If the terminals of the main harness connector are damaged, replace the main harness.

If the terminals of the ESD ECU connectors are damaged, replace the ESD ECU.

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.

Special Tool - Needle Adapter Set: 57001-1457

ESD ECU Power Supply Inspection Connections:

(I) Digital Meter (+) → Terminal 18 (BR/BK) Digital Meter (–) → Battery (–) terminal

Ignition Switch OFF: 0 V

Ignition Switch ON: Battery Voltage

If the reading is out of the specification, check the following.

Main Fuse 30 A (see Fuse Inspection in the Electrical System chapter) Electronic Steering Damper Fuse 10 A (see Fuse Inspection in the Electrical System chapter) Power Source Wiring (see wiring diagram in this section)

If the fuse and wiring are good, replace the ESD ECU (see ESD (Electronic Steering Damper) ECU Removal/Installation in the Steering chapter).

Drive Chain
The drive chain slack and lubrication must be checked each day before riding the motorcycle and must be maintained in accordance with the Periodic Maintenance Chart for safety and to prevent excessive wear. If the chain becomes badly worn or maladjusted - either too loose or too tight - the c ...

Crankshaft Sensor Peak Voltage Inspection
NOTE Be sure the battery is fully charged. Using the peak voltage adapter [A] is more reliable way to determine the condition of the crankshaft sensor than crankshaft sensor internal resistance measurements. Disconnect the crankshaft sensor lead connector (see Crankshaft Sensor ...

Spring Preload Adjustment
To adjust the spring preload, turn the spring preload adjuster [A]. The standard adjuster setting is the 6 turns in from the fully counterclockwise position. WARNINGIf both adjusters are not adjusted equally, handling may be impaired and a hazardous condition may result. B ...
