ECM PROBLEM INSPECTION

PROCEDURE

ED2F36EF

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.

Specification (Resistance)
Between terminal 2 of C01-2 connector and
chassis ground : 1Ω or less
Between terminal 4 of C01-2 connector and
chassis ground : 1Ω or less
Between terminal 6 of C01-2 connector and
chassis ground : 1Ω or less

2.

TEST ECM CONNECTOR: Disconnect the ECM con-
nector and visually check the ground terminals on
ECM side and harness side for bent pins or poor con-
tact 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 vehicle again. If the vehicle 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 vehicle and
check the vehicle. If the problem occurs again, re-
place the original ECM with a new one. If problem
does not occur, this is intermittent problem (Refer to
INTERMITTENT PROBLEM PROCEDURE in BASIC
INSPECTION PROCEDURE)

REPLACEMENT

E7FFA26A

CAUTION

When exchanging ECMS, be sure to input injector
data (7 digits) of each cylinder into a new ECM
using a Hi-scan(pro).

1.

After turning ignition switch off, wait for 30sec..

2.

Remove the battery cable(-).

3.

Remove the ECM connector.

AWJF301G

4.

Unfasten four mounting bolts (A).

A

AWJF303A

5.

Remove the ECM from the air cleaner assembly.

6.

Install a new ECM with air cleaner assembly.

7.

Fasten four mounting bolts.

Tightening torque : 0.8 ~ 1.2kgf·m

8.

Using a Hi-scan(pro), input the injector data (7 digits)
into a new ECM as next procedure.
