CHECK FOR INTERMITTENT PROBLEMS

Hand-held tester only

Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect when the ECM is in check mode with the hand-held tester. In check mode, the ECM uses 1 trip detection logic, which has a higher sensitivity to malfunctions than normal mode (default), which uses 2 trip detection logic.

  1. Clear the DTCs (see «DTC CHECK/CLEAR»(ref-225944-S35824900492006032400000) ).
  2. Set the check mode (see «CHECK MODE PROCEDURE»(ref-225944-S23978259082006032400000) ).
  3. Perform a simulation test (see «HOW TO PROCEED WITH TROUBLESHOOTING»(ref-225941-S24209809792006032400000) ).
  4. Check the connector and terminal (see «ELECTRONIC CIRCUIT INSPECTION PROCEDURE»(ref-225941-S34226502102006032400000) ).
  5. Wiggle the harness and the connector (see «ELECTRONIC CIRCUIT INSPECTION PROCEDURE»(ref-225941-S34226502102006032400000) ).
