SECTION 15 – IQ DISPLAY MODULE (IQDM) AND IQDM-P
DIAGNOSTICS: IQ SYSTEM
DANGER
• See General Warnings on page 1-1.
WARNING
• See General Warnings on page 1-1.
NOTE: For information specific to the IQDM-P handset programming features, see IQ Display Module Programmer
(IQDM-P): IQ System on page 22-1.
The information presented in this section addresses the Series 2 versions of the IQDM-P and IQDM handsets.
2009 Precedent IQ electric vehicles equipped with the Gen II Pedal Assembly will produce a reoccurring
Throttle Fault 1 fault code registered in the vehicle's controller fault history when taking readings with the
IQDM diagnostic module. This occurs due to the Gen II Pedal Assembly having a modular electric throttle with
a throttle position sensor instead of an MCOR. The 1510 series controller that is used with IQ System cars
requires a constant low voltage signal from the MCOR to signal there are no broken wires, loose connector
plugs, etc. between the controller and MCOR. The throttle position sensor loses this connection when the key
switch is turned off, prompting the controller to instantly register the appropriate Throttle Fault 1 code in fault
history. The code can be cleared but will return every time the key switch is turned OFF. It has no ill effect
on the operation of the vehicle and should not be interpreted as a fault that necessitates replacement of the
vehicle's accelerator pedal assembly that contains the throttle position sensor.
There are circumstances in which a legitimate Throttle Fault 1 fault code will register. If the vehicle does
have an issue with the throttle position sensor or its wiring, the fault code will be present in the Current
Faults menu with the key switch in the ON position. This fault code will also most likely be accompanied
by a non-operational vehicle.
The Excel system uses a 1515 series controller that has software preventing this fault code from registering
when the key is switched off. Future IQ system controllers will have software to prevent this as well.

PLUGGING THE HANDSET INTO THE VEHICLE

1. Connect one end of the cable to the port located on the bottom of the handset.
2. Connect the cable adaptor to the IQDM cable.
3. Find the IQDM port on the vehicle (Figure 15-1, Page 15-2).
4. Remove the dust cap from the IQDM port.
5. Align the keyed portion of the plug with the IQDM port and connect the plug to the port.

INTRODUCTORY DISPLAY

Immediately after the handset is connected to the vehicle, it begins loading the vehicle speed controller information.
After a few seconds, the screen displays the following menu items:
• Program (IQDM-P only)
• Monitor
