2. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal A engine control module (ECM) harness side and ground.
‹› If the test lamp does not illuminate, test the ignition circuit for a short to ground, or an open/high resistance. If the circuit tests normal and the
ignition circuit fuse is open, test or replace the fuel injector.
3. Ignition OFF, connect a J 35616-200 between the ignition circuit terminal A and the control circuit ECM harness side, of the appropriate injector
listed below:
*
Injector 1 terminal B
*
Injector 2 terminal C
*
Injector 3 terminal D
*
Injector 4 terminal E
4. Engine cranking, the test lamp should flash for each injector.
‹› If the test lamp is always ON, test the appropriate control circuit for a short to ground. If the circuit tests normal, replace the ECM.
‹› If the test lamp is always OFF, test the appropriate control circuit for a short to voltage or an open/high resistance. If the circuit tests normal,
replace the ECM.
5. Ignition OFF, measure for 10-15 ohms on the engine harness side of C130 between the ignition circuit terminal A and the control circuit of the
appropriate injector listed below:
*
Injector 1 terminal B
*
Injector 2 terminal C
*
Injector 3 terminal D
*
Injector 4 terminal E
