Reading DTCs 1
• Turn the ignition switch ON and count the number of times the MIL (Malfunction Indicator Light) blinks
< NOTE >
• If the MIL (Malfunction Indicator Light) does not output a code (the light does not blink), there may be an open circuit in
the TC terminal system or a failure in the engine ECU.
• If the malfunction indicator light is constantly ON, there may be a short (pinching) in the wiring harness or a failure in
the engine ECU.
• If meaningless DTCs are output, there may be a malfunction in the engine ECU.
• If the MIL (Malfunction Indicator Light) illuminates without outputting a DTC while the engine operates at a minimum
speed of 1000rpm, turn the ignition switch OFF once; then resume the inspection.
Reading DTCs 2
• If an abnormal DTC has been output, check it against the DTC list.
Erasing DTCs from memory
• Remove the ECD fuse (15A); after 15 seconds have elapsed, re-install the fuse.
< CAUTION >
After completing the inspection of the ECD system, erase the DTC memory, and make sure the normal code is output.
