Ecd System (W/ Urea Scr System) Check For Intermittent Problems

Ecd System (W/ Urea Scr System) -- Check For Intermittent Problems


HINT:
GTS only:
Inspect the vehicle ECM using check mode. Intermittent problems are easier to detect with the GTS when the ECM is in check mode. In check mode, the ECM uses 1 trip detection logic, which is more sensitive to malfunctions than normal mode (default), which uses 2 trip detection logic.
  1. Clear the DTCs (LandCruiser RM000000PDK1E5X.html).
  2. Switch the ECM from normal mode to check mode using the GTS (LandCruiser RM000000PDL0YPX.html).
  3. Perform a simulation test.
  4. Check and wiggle the harness(es), connector(s) and terminal(s).
