Diagnostic Trouble Codes
- While 4WD ECU is active, it periodically monitors its inputs and outputs.
If a fault is detected, the Malfunction Indicator Lamp for 4WD is illuminated and flashes at an interval of 0.25 seconds "ON", and 0.25 seconds "OFF".
- When the ignition is turned on, the 4WD ECU tests its ROM and RAM. If there is a fault, the 4WD ECU immediately resets itself and re-tests the ROM and RAM.
If the fault persists, the 4WD ECU continues to reset and re-test until the fault is corrected or the ignition is turned off.
- Diagnostic Trouble Codes will remain in memory until the 4WD ECU is instructed to erase DTC's by the Hi-Scan Pro.
