2000 cadilac seville occasionally doesnt respond when ignition key is inserted, no memory position adjustments, no starter when key turned. is it key or ignition switch. everything usually works fine


Is the security light lit on the instrument when it doesn't start ? The ignition switch on your vehicle doesn't work like you would probably think it does . The ignition switch is input signal to the body control system .
Body Control System Description
The body control system consists of three modules and their associated electrical controls. These modules are as follows:
• The dash integration module (DIM), located on the right hand side of the instrument panel, near the blower motor.
• The instrument panel integration module (IPM), located in the center of the instrument panel, above the radio.
• The rear integration module (RIM), located on the right hand rear of the passenger compartment, behind the rear seat.
Each module integrates input and output controls for two or more functional areas. The inputs and outputs are wired to the closest module to minimize the lenth and amount of the wiring used. All three modules communicate on the Class 2 serial data line, allowing data to be shared among them, as well as with other Class 2 modules on the vehicle as needed.

Each of the three body control modules integrate a number of functional systems under the control of a single module. Each of the modules are connected to the Class 2 serial data line.
Dash Integration Module (DIM)
The dash intergration module (DIM) functions include the following:
• Power moding control (ignition switch states) over Class 2 serial data line
• Control of exterior lamps
• Interior lamps and incandescent dimming
• Steering wheel controls
• Horn relay control for theft activation
• Low side temperature for HVAC compressor
• Hood ajar switch input (export)
• Storage of the clock settings and, sending a message on the class 2 serial data line in response to requests from other modules.

Instrument Panel Integration Module (IPM)
The instrument panel integration module (IPM) functions include the following:
• Front HVAC air delivery and temperature controls
• Ambient light sensor input and twilight delay input for headlights control
• Foglight switch inputs
• I/P dimmer switch input
• Traction control switch input
• Interior lamps switch input
• Key in ignition switch input from the ignition switch
• Fuel door and rear compartment lid release switch input
• Ignition switch headlight control

Rear Integration Module (RIM)
The rear integration module (RIM) functions include the following:
• Fuel level sensor input
• Heated seat controls
• HVAC blower control
• Rear defogger control
• Park brake relay controls
• Various controls for the interior lamps
• Reverse control for the backup lamps and automatic day/night mirror
• Rear foglights control
• Fuel door and rear compartment lid release controls
• Retained accessory power (RAP) control for the sunroof control module
• Ajar switch and tamper switch inputs from the rear compartment lid
• Content theft alarm

At the dealer we would hook up a scan tool and look at the ignition switch inputs to the DIM to see if has correct inputs . Also we would check DTC'S diagnostic trouble codes .
DTC B1805 Ignition Switch Problem

Normal vehicle Class 2 communication does not begin until the system power mode has been identified. The dash integration module (DIM) monitors four discrete wires from the ignition switch contacts in order to determine the present power mode (ignition switch position). The DIM communicates the system power mode to all Class 2 modules on the Class 2 serial data line.

Location of ignition control module 2001 cadilac deville


Ignition Coils/Modules
The electronic ignition system uses an individual ignition coil for each cylinder. There are two separate ignition module assemblies located in the camshaft cover of each cylinder bank. Each ignition module assembly contains an ignition control module and four ignition coils. Each ignition coil connects directly to a spark plug using a boot. This arrangement eliminates the need for secondary ignition wires. The ignition module assemblies receive power from a fused ignition feed. Both ignition module assemblies connect to chassis ground. A Reference Low and four ignition control (IC) circuits connect each ignition module assembly to the PCM. The PCM uses the individual IC circuits to control coil sequencing and spark timing for each ignition coil. The IC circuits transmit timing pulses from the PCM to the ignition control module to trigger the ignition coil and fire the spark plug. The PCM controls ignition system sequencing and timing events

Where is the ignition control module located on a 1992 honda accord-dx?


Ignition control module, is not the same as an ECM, it is termed an "igniter" and is located in the distributor, as part of the reluctor wheel pickup and ignition module.
Generally the entire distributor is replaced as a unit for ease and typical distributor bearing issues.

1989 ford ranger location of ignition control module


Check for a Thick Film Integrated (TFI) Module attached to the outside of the distrfibutor with about an 8 wire plug on it. That is Ford's ignition module. My recollection is the two screws attaching it to the distributor are odd-ball 7/32 in. size. If the module is taken off, use special ford di-electric grease on the base before re-attaching. For heat dissipation.

Where is the ignition modulator located in a 1984 toyota truck


Ignition "modulator"??? I assume you mean "ignition module" or "Ignition control module". If this is what you mean, it is mounted on the ignition coil assembly. Toyota refers to this part as "transistorized ignitor".

Where is the ignition module control located on 1996 ranger 2.3 e


It does not have an ignition control module. The PCM (powertrain control module) fires the coil pack based on signal it recieves from the crankshaft position sensor and the camshaft position sensor.
