90654-ZY3-003 Honda CLIP A, HARNESS (Honda Code 6994354).

Probable Causes
Wiring to the electronic unit injectors
Electronic unit injectors
Engine software and ECMRecommended Actions
Note: The procedures have been listed in order of probability. Complete the procedures in order.
Electrical Shock Hazard. The electronic unit injectors use DC voltage. The ECM sends this voltage to the electronic unit injectors. Do not come in contact with the harness connector for the electronic unit injectors while the engine is operating. Failure to follow this instruction could result in personal injury or death.

Troubleshooting Test Steps Values Results
1. Diagnostic Codes
A. Download the Warranty Report and the Product Status Report (PSR) with Histograms before performing any troubleshooting or clearing any diagnostic codes.
Note: The downloaded information will be required by the Dealer Solutions Network (DSN) if troubleshooting assistance is needed.
B. Use the electronic service tool to check for active or logged diagnostic codes.
Diagnostic codes
Result: A diagnostic code is not active or logged.
Return the unit to service.
Result: A 190–10 diagnostic code is active or logged.
Proceed to Test Step 2.
2. Inspect Electrical Connectors and Wiring
A. Turn the keyswitch to the OFF position. A strong electrical shock hazard is present if the keyswitch is not turned OFF.
B: Thoroughly inspect the connectors at the cylinder head. Refer to Troubleshooting, Electrical Connectors - Inspect for details.
C. Perform a 45 N (10 lb) pull test on each of the wires in the ECM connector that are associated with the injector solenoids.
D.Check the screw for the ECM connector for the correct torque of 6 N m (53 lb in)
E. Check the harness and wiring for abrasions and for pinch points from the injectors to the ECM.
Loose connection or damaged wire
Result: There is a fault in the connector or the wiring.
Repair: Repair any faulty connectors or replace the wiring harness. Ensure that all the seals are properly in place and ensure that the connectors are correctly coupled.
Use the electronic service tool to clear all logged diagnostic codes and verify that the repair eliminates the fault.
Result: All connectors, pins, and sockets are correctly coupled and/or inserted. The harness is free of corrosion, abrasion, and pinch points.
Proceed to Test Step 3.
3. Use the "Injector Solenoid Test"
A. Start the engine.
B. Allow the engine to warm up to the normal operating temperature.
C. Stop the engine.
D. Turn the keyswitch to the ON position.
E. Access the "Injector Solenoid Test" in the electronic service tool by accessing the following screens:
• Diagnostics
• Diagnostic Tests
• Injector Solenoid Test
F. Activate the test.
Note: Do not confuse the "Injector Solenoid Test" with the "Cylinder Cutout Test". The "Cylinder Cutout Test" is used to shut off fuel to a specific cylinder while the engine is running. The "Injector Solenoid Test" is used to actuate the injector solenoids while the engine is not running.
"OK", "OPEN", or "SHORT"
Result: All cylinders indicate "OK".
There is not an electrical fault with the injectors.
Proceed to Test Step 4.
Result: "OPEN" or "SHORT" is indicated on any injector.
Note the cylinders that indicate "OPEN" or "SHORT".
Refer to Troubleshooting, Injector Solenoid - Test to diagnose the cause of the injector circuit fault.
4. Electronic Unit Injectors
A. Use the electronic service tool to perform the automatic "Cylinder Cutout Test". Refer to Troubleshooting, Service Tool Features for more information on the "Cylinder Cutout Test".
Electronic unit injectors
Result: A faulty cylinder is indicated.
Repair: Remove any faulty electronic unit injectors. Refer to Disassembly and Assembly, Electronic Unit Injector - Remove.
Install new electronic unit injectors. Refer to Disassembly and Assembly, Electronic Unit Injector - Install.
Repeat the automatic "Cylinder Cutout Test". If the fault is still present, remove the replacement electronic unit injector and install the original electronic unit injector. Refer to Disassembly and Assembly, Electronic Unit Injector - Remove and Disassembly and Assembly, Electronic Unit Injector - Install. Proceed to Test Step 5.
If the fault is cleared, return the unit to service.
Result: All injectors are OK.
Proceed to Test Step 5.
5. Engine Software and Electronic Control Module (ECM)
A. Make sure that the latest flash file for the application is installed in the engine ECM.
B. Ensure that the ECM has been powered down after the ECM flash file has been updated.
Software updated
Result The 190–10 does not recur after the software has been updated.
Return the unit to service.
Result The 190–10 code is still present after the software has been updated.
Proceed to Test Step 6.
6. Create an Electronic Service Tool Snapshot
A. Select "Snapshot Viewer" on the electronic service tool, using menus: Information -> Snapshot -> Viewer
B. Select the diagnostic code and then click "View Graph".
C. Select the following parameter and then click OK.
Engine Speed
D. Select Save to "File to save" a Snapshot File (*.xml). This file will contain all the data in the snapshot and not only the data shown on the graph.
Note: The downloaded information will be required by the Dealer Solutions Network (DSN) if diagnostic assistance is needed.
Snapshot saved
Result: The electronic service tool snapshot was successfully saved.
