For 1990-2009 cars

### Removal Procedure

Caution: Before servicing any electrical component, the ignition and start switch must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.

1. Turn off all the lamps and accessories.
2. Turn the ignition OFF.
3. Remove the battery ground (negative) cable clamp bolt from the cable clamp.
4. Remove the battery ground (negative) cable from the battery.

### Installation Procedure

Important: Clean any existing corrosion from the battery terminal , the battery cable clamp bolt and the battery cable clamp.

1. Install the battery ground (negative) cable to the battery.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the battery cable clamp bolt to the battery ground (negative) cable clamp.

Tighten
Tighten the battery cable clamp bolt to 6 N·m (53 lb in).

Important: The engine will run extremely poor if the Electronic Throttle Control is not reprogrammed after a power loss.

3. Electronic Throttle Control (ETC):

3.1. | Turn the ignition switch to the RUN position. DO NOT start the engine.

3.2. | Leave the ignition switch in the RUN position for at least three minutes to allow the ETC to cycle and re-learn its home position.

3.3. | Turn the ignition switch to OFF.

3.4. | Start the engine and allow to run for at least 30 seconds.

4. Power Sunroof:

4.1. | Turn the ignition switch to the RUN position.

4.2. | Turn the power sunroof switch to the closed position. After the sunroof fully closes and the motor stops, press and hold in the switch for three seconds.

4.3. | Turn the power sunroof switch to the tilt position. After the sunroof reaches the tilt position and the motor stops, press and hold in the switch for three seconds.

4.4. | Turn the power sunroof switch to the full open position. After the sunroof is fully open and the motor stops, press and hold in the switch for three seconds.

4.5. | Turn the power sunroof switch to the closed position. After the sunroof fully closes and the motor stops, press and hold in the switch for three seconds.

5. Power Windows:

5.1. | Repeat these steps for each window.

5.2. | Turn the ignition switch to the RUN position.

5.3. | Press the power window switch to the down position. After the window is in the full down position, press and hold the switch in the down position for three seconds.

5.4. | Press the power window switch to the up position. After the window is in the full up position, press and hold the switch in the up position for three seconds.

6. Heat and A/C Control Head:

6.1. | Turn the ignition switch to the RUN position.

6.2. | Simultaneously press the AUTO and OFF buttons (located on the heat and A/C control head) for at least five seconds.

6.3. | After initiation, the stepper motors will cycle from one stop to the other. You may hear the motors cycling while calibrating.

7. Power seat memory, power mirror memory and radio channel preset memory:

7.1. | The power seat and power mirror memory are stored in non-volatile memory in the seat memory module.

Reprogramming will not be necessary after a power loss. However, if a component of the seat or mirror is replaced, the module will require programming with the scan tool.

7.2. | The radio channel presets are stored in non-volatile memory in the radio.

Reprogramming will not be necessary after a power loss. However, if the radio is replaced, the station presets must be manually reset.
