NOTE
Be sure the battery is fully charged.
Do not disconnect the ECU connectors.

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
Input Voltage Standard: Battery Voltage
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).
