FUEL INJECTOR OPERATION INSPECTION CHART

STEP	INSPECTION	RESULTS	ACTION
1	Start the engine and warm it up until normal operating temperature. Connect the M-MDS to the DLC-2. Select the INJ#1, INJ#2, INJ#3 and INJ#4 PIDs. (See ON-BOARD DIAGNOSTIC TEST .) Turn the fuel injector from on to off using the PIDs each cylinder. Does the engine speed drop?	Yes	Fuel injector work properly.
1		No	Go to the next step.
2	Disconnect the fuel injector that the engine speed does not drop at Step 1. Switch the ignition to ON. Measure the voltage between suspect fuel injector terminal A (wiring harness-side) and body ground. Is the voltage B+?	Yes	Go to the next step.
2		No	Repair or replace for open or short circuit between fuel injector terminal A and fuel pump relay terminal C.
3	Inspect for open or short circuit between suspect fuel injector terminal B and following PCM terminals: Fuel injector No. 1 PCM terminal 2BB Fuel injector No. 2 PCM terminal 2BC Fuel injector No. 3 PCM terminal 2BD Fuel injector No. 4 PCM terminal 2AZ Is there any malfunction?	Yes	Repair or replace suspected wiring harness and connector.
3		No	Go to the next step.
4	Inspect the suspect fuel injector. (See FUEL INJECTOR INSPECTION .) Is the fuel injector normal?	Yes	Replace the PCM. (See PCM REMOVAL/INSTALLATION .)
4		No	Replace the fuel injector. (See FUEL INJECTOR REMOVAL/INSTALLATION .)

FUEL INJECTOR OPERATION INSPECTION CHART

STEP	INSPECTION	RESULTS	ACTION
1	While cranking the engine, inspect for fuel injector operation sound at each cylinder using a soundscope. Is the operation sound heard?	Yes	Fuel injector work properly.
1		No	Go to the next step.
2	Disconnect the fuel injector that the fuel injector operation sound does not heard at Step 1. Switch the ignition to ON. Measure the voltage between suspect fuel injector terminal A (wiring harness-side) and body ground. Is the voltage B+?	Yes	Go to the next step.
2		No	Repair or replace for open or short circuit between fuel injector terminal A and fuel pump relay terminal C.
3	Inspect for open or short circuit between suspect fuel injector terminal B and following PCM terminals: Fuel injector No. 1 PCM terminal 2BB Fuel injector No. 2 PCM terminal 2BC Fuel injector No. 3 PCM terminal 2BD Fuel injector No. 4 PCM terminal 2AZ Is there any malfunction?	Yes	Repair or replace suspected wiring harness and connector.
3		No	Go to the next step.
4	Inspect the suspect fuel injector. (See FUEL INJECTOR INSPECTION .) Is the fuel injector normal?	Yes	Replace the PCM. (See PCM REMOVAL/INSTALLATION .)
4		No	Replace the fuel injector. (See FUEL INJECTOR REMOVAL/INSTALLATION .)
