Molex Connector Probing
The most recommended and safest method to
probe ECM connector terminals is to use the
ADAPTER TOOL (P/N 529 036 166)
prevent deforming or enlarging terminals which
would lead to bad ECM terminal contact creating
intermittent or permanent problems.
529036166
Disconnect the ECM connector and reconnect on
the tool connector. Probe required terminals di-
rectly in the tool holes.

or enlarge the terminals and create intermit-
tent or permanent contact problems.
Molex Connector Inspection
Before replacing an ECM, always check electrical
connections.

1. Ensure connector locking mechanism is func-
. This tool will
tioning properly.
2. Ensure all wire terminals (pins) are properly
locked in the connector.
3. Ensure they are very tight, make good contact
with the pins in the ECM.
4. Ensure the pins in the harness connector
and the ECM connector are clean, shiny and
corrosion-free.
5. Check wiring harness for signs of scoring.
NOTE: A "defective ECM module" could possi-
bly be repaired simply by disconnecting and recon-
necting it.

Molex Connector Terminal Removal
(Harness Connector)
To remove a signal terminal from the ECM har-
ness connector, use the
MOVER 2.25 (P/N 529 036 175)
To remove a power terminal, use the
NAL REMOVER 3.36 (P/N 529 036 174)
Never probe directly on ECM har-
