continuously available to each injector. The engine Electronic Control
Module (ECM) determines the correct time and duration to activate
each injector.
Test Step 1. Check for Fuel Injector
Diagnostic Codes.
N OT E
Injectors 1-3 share a common ground in the Engine ECM. A failure of
the ECM could cause all three codes to appear.
Injectors 4-6 share a common ground in the Engine ECM. A failure of
the ECM could cause all three codes to appear.
1. Connect MSD (WP 0006). Select
Engine ECM C6.6 120M.
2. Start engine or attempt to start
engine.
3. At the MSD, check if all three
0001-05, 0002-05, and 0003-05
diagnostic codes 0001-05, 0002-
Diagnostic Codes are Active -
05, and 0003-05 are active.
Replace the Engine ECM (WP 0067).
4. At the MSD, check if all three
0004-05, 0005-05, and 0006-05
diagnostic codes 0004-05, 0005-
Diagnostic Codes are Active -
05, and 0006-05 are active.
Replace the Engine ECM (WP 0067).
0004-02 Only Active - Proceed to
Test Step 2.
Test Step 2. Replace Fuel Injector.
1. Replace fuel injector #4 (WP
All Six Injectors Indicate Success -

Fault has been cleared.
2. Perform Fuel System Verification
Injector #4 Indicates Fail - Proceed
Test (WP 0035).
to Test Step 3.
Test Step 3. Check ECM Flash
Files.
Verify correct Engine ECM flash files
Flash Files Bad - Replace ECM flash
files (WP 0008).
Flash Files Good - Replace Engine
ECM (WP 0067).

System Response:
Current Below Normal
A warning will appear on instrument
panel. ECM will log diagnostic code.
Possible Performance Effect:
Engine will have low power and/or
rough running.
