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

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

ESD ECU Installation

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

ESD ECU Power Supply Inspection

Lift up the front portion of the fuel tank, and hold it with a suitable bar or block (see Fuel Tank Removal in the Fuel System (DFI) chapter).
Visually inspect the ESD ECU connectors.

ESD ECU Power Supply Inspection

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

Remove the ESD ECU (see ESD (Electronic Steering Damper) ECU Removal in the Steering chapter).
Visually inspect the terminals [A] of the ESD ECU connector.

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.

Turn the ignition switch to OFF.
Disconnect the ESD ECU connector [A].
Set the hand tester [B] to the × 1 Ω range and check the following wiring for continuity.

Special Tool - Hand Tester: 57001-1394

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.

ESD ECU Power Supply Inspection

Connect the ESD ECU connector.
Connect a digital meter [A] to the connector [B] with the needle adapter set.

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).

Battery Removal
Turn off the ignition switch. Remove the front seat (see Front Seat Removal in the Frame chapter). Slide the red cap [A]. Disconnect the negative (–) cable [B] and then positive (+) cable [C]. NOTICE Be sure to disconnect the negative (–) cable first. Remove the band [D] ...

Crankshaft Side Clearance Inspection
Insert a thickness gauge [A] between the thrust washer [B] on the crankcase and the crank web [C] at the #3 main journal to determine clearance. If the clearance exceeds the service limit, replace the thrust washers as a set and check the width of the crankshaft #3 main journal. Cra ...
