Ignition control module corrola

Which one ? do you know ?
The body control system consists of the following 3 modules:
• The Dash Integration Module (DIM)
• The Instrument Panel 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 module is connected to the Class 2 serial data circuit, many of the control functions are implemented by Class 2 messages.
An after you replace or change one of these modules it has to be programmed .
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 .
So , what problem are you having ?

The auto part stores can tell you as they have a parts locator. More than likely the map sensor is not the problem. Often the problem is a failing ignition control module/amplifier or the failing crankshaft position sensor.

You might want to check fuel pressure at the fuel rail as your pump or regulator may be going

Each ignition control module (ICM) has the following circuits:
An ignition 1 voltage circuit A chassis ground An ignition control circuit for each cylinder A low reference circuit
The PCM controls spark by pulsing the ignition control circuits to the ICM to trigger the coils and fire the spark plugs. The PCM and ICM are internally protected against shorts to power and ground on the ignition control circuits.

The spark plugs are connected to each coil by a short boot. The boot contains a spring that conducts the spark energy from the coil to the spark plug. The spark plugs are tipped with platinum for long wear and higher efficiency.

Removal & Installation
2.2L (L61) Engine

1. Turn OFF the ignition.
2. Remove the accelerator cable from the bracket.
3. Remove the accelerator cable bracket bolt.
4. Remove the accelerator cable bracket.
5. Disconnect the ignition control module (ICM) harness connector.
6. Remove the ICM retaining screws.
7. Remove the ICM from the ignition coil housing.
   

To install:

1. Install the ignition control module in the ignition coil housing.
2. Install the ICM retaining screws. Tighten the retaining screws.
3. Connect the ICM harness connector.
4. Install the accelerator cable bracket.
5. Install the accelerator cable bracket bolt. Tighten the retaining screws.
6. Install the accelerator cable to the bracket.

2.2L (Ln2) Engine

1. Remove the air cleaner outlet from the air cleaner.
2. Remove the ICM electrical connectors (1) and spark plug wires (2).
3. Remove the ignition coils bolts (3).
4. Remove the ignition coils and ICM assembly.
5. Installation is the reverse of the removal procedure.
   

2.4L Engine

1. Disconnect the negative battery cable.
2. Remove the accelerator cable from the hold down clip.
3. Remove the cruise control cable, if applicable.
4. Remove the bolt from the fuel line retaining clip.
5. Disconnect the 11-pin harness connector for the ignition control module (ICM).
6. Remove the bolts from the ignition coil and the ICM assembly-to-camshaft housing.
7. Remove the ignition coil and ICM assembly from the engine.
8. Remove the screws that retain the housing to the cover.
9. Disconnect the coil harness connector from the ICM.
   CAUTION When removing the housing from the cover, make sure the ground strap stays in place.
   
10. Remove the housing from the cover.
11. Remove the screws that retain the ICM to the cover.
12. Remove the ICM from the cover.

To install:

CAUTION DO NOT wipe grease from the module or coil if the same module is to be replaced. If a new module is to be installed, a package of silicone grease will be included with the module. Spread the grease on the metal face of the module and on the cover where the module seats. This grease is necessary for module cooling.

1. Install the ICM to the cover.
2. Install the screws that retain the ICM to the cover.
3. Install the ground strap, if necessary.
4. Connect the ignition coils connector to the ICM.
   CAUTION When installing the housing to the cover, make sure the ground strap stays in place.
5. Install the housing to the cover.
6. Install the screws that retain the housing to the cover.
7. Install the spark plug boots and the retainers to the housing, if necessary.
8. Install the ICM assembly to the engine while carefully aligning the spark boots to the spark plug terminals.
   CAUTION The ICM cover bolts must be installed using isolator washers with the rubber side facing down.
   
9. Install the bolts that retain the ICM assembly to the camshaft housing after coating the bolt threads with LOCTITE, or equivalent. Tighten the bolts to 16 ft. lbs. (22 Nm).
10. Connect the ICM 11 pin harness connector.
11. Install the bolt to the fuel line retainer clip.
12. Install the accelerator cable into the hold down clip.
13. Install the cruise control cable, if applicable. Connect the negative battery cable.

Hope this help (remember comment and rated this).

CHECK IGNITION MODULE FUSE.AND CHECK FOR POWER GOING TO MODULE AND COILS.IF NO POWER PROBLEM IN IGNITION MODULE FUSE OR LOOSE BROKEN WIRE.IF POWER GOING TO IGNITION MODULE.THE IGNITION MODULE FAULTY.TO SAVE MONEY AND TIME.HAVE CAR SCANNED TO MAKE SURE YOU DONT HAVE ECM OR PCM PROBLEMS.YOU DONT WANT TO BUY A IGNITION MODULE IF YOU DONT NEED IT BECAUSE THEY COST FROM $100.00 TO $200.00.THATS WHY SCAN IT FIRST.

1. Easy job and should have no problems here some help
   Disconnect the negative battery cable.
2. Detach the engine control sensor wiring connector from the ignition control module by pressing down on the locking tab where it is stamped PUSH, and remove the connector.
3. Remove the ignition module and the module bracket from the front fender apron.
4. Unfasten the two ignition module retaining screws, then remove the ignition module form the module bracket.

To install:


Fig. Fig. 2: The ignition module on 1994-95 vehicles is mounted on the front fender apron

1. Install the ignition module onto the module bracket. Tighten the retaining screws to 24-33 inch lbs. (2.7-3.7 Nm).
2. Position the ignition module and bracket assembly onto the front fender apron. Secure with the retaining bolt and tighten to 35-50 inch lbs. (4-5.6 Nm).
3. Attach the engine control sensor wiring connector to the ignition module.

6. Hope this Helps !

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.

Sounds like either the ignition module and or a coil pack is the culprit. I dont remember what year they changed it but if your is the one where the coil packs/module are located on the back of the motor they are a little tricky to get to. You need to remove dog bone mount and replace with a tool that will pull the motor forward so you can gain easier access...good luck. Hopefully yours are right on the top where they should have been since day one... :-)

have you replaced your ignition module?
