DIAGNOSIS AND TESTING)
Diagnostic Test
1.
DTC IS ACTIVE
NOTE: This DTC can set as a result of a fault in any of the injector circuits. Be sure to check all injector
circuits before replacing an injector and all injectors before replacing a module.
Ignition on, engine not running.
With the scan tool, Clear DTCs in the Engine Control Module.
Attempt to start the engine and test drive the vehicle.
With the scan tool, select View DTCs.
Is the status Active for this DTC?
Yes
>> Go To 2
No
>> Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
2.
(K663) FUEL INJECTOR HIGH-SIDE COMMON CIRCUIT SHORTED TO VOLTAGE
Turn the ignition off.
Disconnect the Fuel Injector 2 harness connector.
Disconnect the Engine Control Module harness connectors.
Remove the Main Relay.
Connect a jumper wire between cavity B7 and cavity B9 of the Main
Relay Connector.
Turn the ignition on.
Measure the voltage of the (K663) Fuel Injector High-Side Common cir-
cuit in the Fuel Injector 2 harness connector.
Is there any voltage present?
Yes
>> Repair the (K663) Fuel Injector High-Side Common circuit
for a short to voltage.
Perform the ECM Verification Test Ver. 1. (Refer to 9 -
