Ecd System Check For Intermittent Problems

Ecd System -- Check For Intermittent Problems


HINT:
GTS only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with an 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). Normal mode uses 2 trip detection logic.
  1. Clear the DTC(s) (LandCruiser RM000000VR600WX.html).
  2. Switch the ECM from normal mode to check mode using the GTS (LandCruiser RM000000VR700UX.html).
  3. Perform a simulation test (LandCruiser RM000003YMI00MX.html).
  4. Check and wiggle the harness(es), connector(s) and terminal(s) (LandCruiser RM000003YMI00MX.html).
