If no voltage is indicated, go to next step.
95 at breakout box while performing wiggle test. Also measure voltage between negative battery terminal and terminal No. Wiggle and bend small sections of wiring harness starting at IDM connector and work toward PCM. Measure voltage between negative battery terminal and test pin No. If any resistance reading changes to 10,000 ohms or less, locate and repair short to ground in Gray/White wire or Brown/Orange wire.ġ2) Check For Intermittent Short To Power If both resistance readings stay at more than 10,000 ohms, go to next step. Also measure resistance between negative battery terminal and terminal No. Measure resistance between negative battery terminal and test pin No. If any resistance reading changes to more than 5 ohms, locate and repair open circuit in Gray/White wire or Brown/Orange wire between PCM and IDM.ġ1) Check For Intermittent Short To Ground If both resistance readings stay at 5 ohms or less, go to next step. Also measure resistance of Brown/Orange wire between terminal No. Wiggle and bend small sections of wiring harness starting at IDM connector and working toward PCM. Measure resistance of Gray/White wire between terminal No. Install Breakout Box (014-00950), leaving PCM disconnected. Disconnect PCM 104-pin connector and inspect for damaged pins, corrosion and loose wires. IDM is located in left side of engine compartment. If no DTCs are present, go to next step.ġ0) DTC P1316 Or P1670: Check For Intermittent Open If any DTCs are present, perform appropriate test and repair as necessary. IDM DTCs are cleared by using CLEAR ALL command from the RETRIEVE/CLEAR CONTINUOUS DTCs menu on scan tool. An intermittent fault will store a DTC in the IDM. Injector faults are stored in the IDM and reported to PCM during KOEO ON-DEMAND SELF-TEST and KOEO INJECTOR ELECTRICAL SELF-TEST. This DTC indicates IDM DTCs are stored in the IDM. Perform this test when directed by QUICK TEST. Clear DTCs and repeat QUICK TEST procedures to ensure all electronic engine control systems are working properly and DTCs are no longer present. DO NOT pierce wires.Īfter each service or repair procedure has been completed, reconnect all components.
The Injector Driver Module (IDM) supplies 115-volts DC into each fuel injector connected to engine wiring harness. TEST FJ: INJECTOR DRIVER MODULE (IDM) FEEDBACKĮnsure negative battery cables are disconnected before disconnecting engine wiring harness. Steps that are not relevant have been omitted. Percentage does not work when diagnosing faults, 1 % can be equivalent to 100 %.
