Kawasaki Ninja Service Manual: Stick Coil Input Voltage Inspection

Kawasaki Ninja Service Manual / Self-Diagnosis System / Stick Coils #1, #2, #3, #4: (Service Code 51, 52, 53, 54) / Stick Coil Input Voltage Inspection

NOTE

Be sure the battery is fully charged.

Turn the ignition switch to OFF.
Remove the ECU (see ECU Removal in the Fuel System (DFI) chapter).

Do not disconnect the ECU connectors.

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

Stick Coil Input Voltage Inspection

Special Tool - Needle Adapter Set: 57001-1457

Stick Coil Input Voltage Connections to ECU Connector: For Stick Coil #1 Digital Meter (+) → BK lead (terminal 65) Digital Meter (–) → Frame Ground terminal

For Stick Coil #2

Digital Meter (+) → BK/R lead (terminal 52) Digital Meter (–) → Frame Ground terminal

For Stick Coil #3

Digital Meter (+) → BK/W lead (terminal 78) Digital Meter (–) → Frame Ground terminal

For Stick Coil #4

Digital Meter (+) → BK/O lead (terminal 51) Digital Meter (–) → Frame Ground terminal

Measure the input voltage to each primary winding of the stick coils with the engine stopped, and with the connectors joined.
Turn the engine stop switch to run position.
Turn the ignition switch to ON.

Input Voltage Standard: Battery Voltage

Turn the ignition switch to OFF.

If the input voltage is out of the standard, check the wiring for continuity (see Stick Coil Circuit)

Special Tool - Hand Tester: 57001-1394

If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).

If the input voltage is within the standard, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).

If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).
