TEST PROCEDURES

The following test procedures enable the technician to test the IQDM and IQDM-P handsets and the components of the
Excel System vehicle that are related to the proper operation of the handset.

WARNING

• If wires are removed or replaced, make sure wiring and wire harness is properly routed and secured.

Failure to properly route and secure wiring could result in vehicle malfunction, property damage,
personal injury, or death.

Index of Test Procedures

1 – Handset Cord
2 – Handset Cord Adaptor
3 – IQDM Ports

TEST PROCEDURE 1 – Handset Cord

See General Warnings on page 1-1.

1.

Using a multimeter set for 200 ohms, place the red (+) probe into one of the terminals on the end of the cord with
the square plug.

2.

Place the black (–) probe on each of the pins, one at a time, on the plug on the other end of the cord.

3.

The multimeter should indicate continuity on only one pin. If any other reading is obtained, the cord must be
replaced.

4.

Repeat the procedure three more times, each time with the red (+) probe inserted into a different terminal on
the end of the cord with the square plug.

TEST PROCEDURE 2 – Handset Cord Adaptor

See General Warnings on page 1-1.

The procedure for testing the handset cord adaptor is similar to the cord test.

1.

Using a multimeter set for 200 ohms, place the red (+) probe into one of the terminals on the end of the adapter
with the square plug.

2.

Place the black (–) probe on each of the pins, one at a time, on the other plug of the adaptor.
