• Digital Multimeter KS-AHM-32-003 (1) or a
commercially available digital multimeter
• Backprobe Set 07SAZ-001000A (2)
1. Connect the backprobe adapters (A) to the stacking
patch cords (B), and connect the cords to a digital
multimeter (C).
2. Using the wire insulation as a guide for the
contoured tip of the backprobe adapter, gently slide
the tip into the connector from the wire side until it
touches the end of the wire terminal.
3.
Do not puncture the insulation on a wire.
Punctures can cause poor or intermittent
electrical connections.
Use this procedure if you need a known-good PCM to
test a vehicle. It allows you to swap a PCM from a
‘‘donor’’ vehicle without having to program it to the test
vehicle’s ignition key.
1. Cut a temporary ignition key for the test vehicle
with a non-immobilizer key blank.
2. Remove the PCM from the test vehicle.
3. Write the test vehicle’s VIN on the PCM you just
removed to avoid confusing it with the donor
vehicle’s PCM.
4. Remove the known-good PCM from the donor
vehicle, and install it in the test vehicle.
5. Tape the donor vehicle’s ignition key head-to-head
to the test vehicle’s temporary key (A). The PCM
will recognize the code from the donor vehicle’s
key (B) and allow you to start the engine with the
temporary key.
6. After completing your tests, reinstall both PCMs,
and destroy the temporary key.

If you cannot get to the wire side of the connector
or the wire side is sealed (A), disconnect the
connector and use the backprobe set to probe
the terminals (B) from the terminal side. Do not
force the probe into the connector.
