Note
1) Check the LED power lamp of the IDSS interface. Does the LED power lamp illuminate?
Yes
=>Go to USB cable connection check.
No
=>Go to Smart cable and USB cable inspection.
1) Inspect for poor connections at the USB cable of the computer and IDSS interface.
2) Repair the connections as necessary.
Procedure completion
1) Inspect for poor connections at the smart cable of the DLC and IDSS interface. Is the connection status normal?
2) Inspect for poor connections at the USB cable of the computer and IDSS interface. Is the connection status normal?
3) Are all of the results normal?
Yes
No
Repair the connections as necessary.
1) Turn OFF the ignition switch.
2) Inspect the METER(+B) 10A fuse for a blowout. Is the result normal?
Yes
No
Replace the fuse. If the fuse blows out again, repair the short to ground in the circuits relating to the METER(+B) 10A fuse.
1) Inspect for poor connections at the DLC (C19). Is the connection status normal?
Refer to "RHD DLC" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "LHD DLC" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to Inspection for open circuit in DLC battery power supply circuit.
No
Repair the connections as necessary.
1) Connect a test lamp between the DLC battery power supply circuit (pin 16 of C19) and the body ground. Does the test lamp illuminate?
Refer to "RHD DLC" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "LHD DLC" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to Inspection for open circuit in DLC ground circuit.
No
Repair the open circuit in the DLC battery power supply circuit.
1) Inspect each DLC ground circuit (pins 4 and 5 of C19) for an open circuit or high resistance. Is the result normal?
Refer to "RHD DLC" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "LHD DLC" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
Go to Intermittent conditions of engine.
Refer to "202.Engine 15D.Symptom(4JJ3 with DPD) intermittent conditions of engine".
No
Repair the circuit and clean or tighten the ground terminal as necessary.
1) Connect the scan tool to the DLC.
2) Power up the scan tool. Does the scan tool power up?
Yes
The system is normal.
No
