ECM Replacement
1. Turn ignition switch OFF and disconnect the negative
(-) battery cable. .
2. Remove the cover of the ECM & relay box
3. Disconnect the ECM connector
4. Install a new ECM.
ECM Problem Inspection Procedure
1. TEST ECM GROUND CIRCUIT: Measure resistance
between ECM and chassis ground using the backside
of ECM harness connector as ECM side check point. If
the problem is found, repair it.
2. TEST ECM CONNECTOR: Disconnect the ECM
connector and visually check the ground terminals on
ECM side and harness side for bent pins or poor
contact pressure. If the problem is found, repair it.
3. If problem is not found in Step 1 and 2, the ECM
could be faulty. If so, replace the ECM with a new
one, and then check the engine again. If the engine
operates normally then the problem was likely with
the ECM.
4. RE-TEST THE ORIGINAL ECM : Install the original
ECM (may be broken) into a known-good engine and
check the engine. If the problem occurs again, replace
the original ECM with a new one. If problem
does not occur, this is intermittent problem (Refer to
INTERMITTENT PROBLEM PROCEDURE in BASIC
