Troubleshooting the -5 Cylinder Injector : Current Below Normal Code
Illustration 1 g01336507
Schematic for the 16-cylinder injectors

Schematic for the 20-cylinder injectors
Electrical Shock Hazard. The unit injector system uses 90 - 120 volts. The ECM sends this signal to the unit injectors. Do not come in contact with the unit injector harness connector while the engine is operating. Failure to follow this instruction could resulting in personal injury or death.

Troubleshooting Test Steps Value Result
A. Check for an Intermittent High Resistance Short Circuit to Ground.
1. Disconnect the rail harness from the ECM. Inspect the connectors and terminals for moisture, corrosion, and other damage. Inspect the condition of the wires. Perform a
45 N (10 lb) pull test on the wires.
Connectors and wiring Result: A problem with the connectors or wiring is found..
Repair the parts, as needed.
Stop
Result: The connectors and wiring appear to be OK.
Proceed to the next test step.
2. On the rail harness, locate any one of the three terminals for the two injectors that have the -5 code.
3. Measure the resistance from the terminal on the rail harness to chassis ground. Ensure that the ground connection is good.
