DIAGNOSIS
DI ENG SM - 2004.4
Help
- The main relay is stuck ; Shut down.
- Resistance of main relay: 92 Ω ± 9 Ω
(at 20°C)
- Check the main relay wiring harness.
- Check the ECU wiring harness.
• Check the ECU pin #3, 4, 5 for open
and short.
- If the forced operation is not available,
replace the ECU.
- Check the fuse for main relay
- The vehicle speed signal through CAN
communication is faulty.
- Check the CAN communication line for
open and short.
- Check the ABS/ESP and TCU commu-
nication lines.
- Check the ECU wiring harness.
- Replace the ECU if required.
- Malfunction reference supply voltage
