How to replace starter switch assembly in 2001 pontiac bonneville


Starter switch ? You do mean ignition switch , the thing on the dash or steering column that you stick the key in ! You car not starting ? The ignition switch isn't the same anymore , sends Discrete Ignition Signals to a module ,in the case of your vehicle it is the DIM - dash integrated module.
The body control system consists of the following 3 modules:
?€¢
The dash integration module (DIM)


?€¢
The instrument panel integration module (IPM)


?€¢
The rear integration module (RIM)

Each of the 3 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; many control signals are implemented by Class 2 messages.
On vehicles that have several control modules connected by serial data circuits, one module is the power mode master (PMM). On this vehicle the PMM is the DIM. The PMM receives 4 signals from the ignition switch.
To determine the correct power mode the PMM uses the following circuits:
?€¢
Accessory voltage


?€¢
Ignition 1 voltage


?€¢
Ignition 3 voltage


?€¢
Off/Run/Crank voltage


Your best bet would be to take to a repair shop that has knowledge of this type system . You probably don't need an ignition switch.
Discrete Ignition Signals Those modules that have discrete ignition signal inputs also remain in the state dictated by the last valid PMM message received on the serial data circuits. They then check the state of their discrete ignition input to determine the current valid state. If the discrete ignition input is active, battery positive voltage, the modules will fail-safe to the RUN power mode. If the discrete ignition input is not active, open or 0 voltage, the modules will fail-safe to OFF-AWAKE. In this state the modules are constantly checking for a change status message on the serial data circuits and can respond to both local inputs and serial data inputs from other modules on the vehicle.

2004 pacifica sunroof wont open or do anything . When I press the button i hear nothing no click no noise at all . All my fuses are working but i was told it could possibly be a relay ? any ideas woul


  1. Check the B+ 40 amp fuse in the Integrated Power Module (IPM). If OK, go to Step 2. If not OK, repair the shorted circuit or component as required and replace the inoperative fuse.
  2. Check the Accessory delay 20 amp fuse in the IPM. If OK, go to Step 3. If not OK, repair the shorted circuit or component as required and replace the inoperative fuse.
  3. Partially remove the headliner to access the sunroof motor/module.
  4. Disconnect the motor/module electrical connector. Using a voltmeter check for Battery voltage at the B+ terminal of the harness connector. If OK, go to Step 5. If not OK, repair the B+ circuit as necessary.
  5. With the ignition switch in the "RUN" position check for Battery voltage at the Accessory Relay Output terminal of the harness connector. If OK , go to Step 6. If not OK repair the Accessory Relay Output circuit as necessary.
  6. Using an ohmmeter test for continuity between the harness connector ground circuit and a known good ground. Continuity should be present. If OK go to Step 7. If not OK, repair the open ground circuit as necessary.
  7. Turn the ignition switch to the "OFF" position. Reconnect the motor/module electrical connector. With the ignition switch in the "RUN" position check for battery voltage on the "VENT", "CLOSE" and "OPEN" circuits at the back side of the motor/module connector. If OK, go to Step 8. If not OK replace the motor/module assembly

Cylinder 1 is not firing


Instructions1 Use a wiring diagram for the year model of your vehicle. Locate the terminals running into and out of the ignition module. Placement of the module varies from model to model so check the appropiate service manual of your vehicle for the exact location.
2 Turn the ignition on and use your DVOM to check for voltage to the ignition module and the positive terminal of the ignition coil. Place the negative lead of your DVOM to a solid ground and use the positive lead to probe the wires running to the ignition module and to the ignition coil.
3 If your DVOM shows that voltage is present at both locations, remove the DVOM leads and set the meter aside. Connect the ground lead from the 12-volt test light to the negative terminal on the ignition coil. Have your partner crank the engine over several times. Your test light should flicker on and off. If so, your module is working properly and no further testing is necessary.
4 If your test light does not flicker on and off, visually inspect the wires running into and out of the ignition module. Look for burn marks, melted wire insulation and breaks in the wires. Use your wire splicing tool to remove the bad area in the wire and use your wire connectors and splicing tool to repair the faulty wires.
5 Use your DVOM to check for an open circuit condition in the primary coil winding. Touch the negative probe to the negative terminal on the ignition coil, touch the positive lead to the positive terminal. Set the meter to read ohms. If the reading shows infinite ohms, your ignition module is faulty and should be replaced. Follow the service manual instructions for replacing your ignition coil.
6 Look to see if the DVOM test shows low to no ohms; if so, then you have a faulty ignition module that will have to be replaced. Follow the service manual instructions for your vehicle to replace the module.
Thanks

I have had the ignition module fail 5 times in the past year.It only happens when i go to start my car.What might be the problem?


If this concern is encountered, inspect circuits 406 (IC Control for 2/3 Coil) and 423 (IC Control for 1/4 Coil) for an intermittent short to ground or poor connection on either end. Depending on the model, these circuits may short on the AC lines near the AC compressor, on the transmission mount, or on the transmission lines where they enter the transmission. If there is no problem found with these circuits, inspect the ignition control module ground to ensure that it is clean and tight.

If there is no problem found after performing the suggestions above and the SI diagnostics lead to ignition module replacement, replace the ignition module as directed but also replace all of the spark plugs and clean the ignition module ground to possibly prevent future ignition module damage. ( use OEM plugs) Before installing the new ignition module. If the spark plugs are worn sightly or have a high resistance They will cause the ignition module to repeatedly fail.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Codes p0351 miss and is goverened at 2800 rpms.


P0351 is Ignition Coil A Primary/Secondary Circuit Malfunction.
Possible causes: - Open or short in the ignition coil circuit - Ignition coil circuit shorted to ground - Ignition coil connector - Damaged ignition coil - Damaged PCM or
Possible solution - If damage, repair ignition coil circuit - Replaced ignition coil - Replaced PCM or ECM When is the code detected? The test fails when the Powertrain Control Module (PCM) or Electronic Control Module(ECM) does not receive a valid pulse signal from the ignition coil.
P0351 Description: The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.
Hope this helps :)

Miss fires and stots off when I give it gas as codes 1391 ,0351, 0352, 0353,


P1391 - Not a valid obd code.
B1391 - Oil Level Switch Circuit Failure
C1391 - Not a valid obd code.
U1391 - Not a valid obd code.
Its possible you may have misread this code. If it is B1391 that would be the only code with 1391 for your vehicle.

P0351 - Ignition Coil A Primary / Secondary Circuit Malfunction. The ignition signal from the Powertrain Control Module or Electronic Control Module is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.

Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM

P0352 - Ignition Coil B Primary / Secondary Circuit Malfunction.
Same repair info as P0351.

P0353 - Ignition Coil C Primary / Secondary Circuit Malfunction.
Same repair info as P0351



Solutions:
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced

Where is the ignition coil module on a 1994 Mazda 626


The ignition module is integrated within the ignition coil itself, and the only repair possible is to replace the entire coil assembly. There are six ignition coils, therefore there are six ignition modules.

This problem is normally caused by a faulty ignition module, which is located inside the distributor. They seem to be a weak point on Mazda 323s of this era. Open the distributor, and remove the rotor button. There is a round plastic cover over the ignition module, which must be removed. The ignition module is semi circular, and has four wires attached to it, via small screws. Take note of the location of each wire, and unscrew each one. The ignition module can be unscrewed with a phillips head screw driver, and removed. When fitting the replacement module, you must cover it with the heat sink compound that is supplied with the new module (mechanics sometimes refer to this compound as ignition module grease). Without the heat sink compound, the new module will over heat, and burn out. You should be able to replace the module in 15 minutes, it is very easy to do.

2000 Saturn SL2 - replaced ignition then BCM failed. Related?


the problem is not the bcm. the passlock security sensor is in the cylinder and housing, if the cyl and or housing was replaced the system must be relearned. if you replace the bcm you still need to relearn the system or it still will not start.
