Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.

POWERTRAIN CONTROL MODULE (PCM)
Notice: To prevent possible electrostatic discharge damage to the [1][2]PCM do not touch the connector pins or soldered components on the circuit board.
ELECTROSTATIC DISCHARGE (ESD) DAMAGE
Electronic components used in the control systems are often designed to carry very low voltage. Electronic components are susceptible to damage caused by electrostatic discharge. Less than 100 volts of static electricity can cause damage to some electronic components. By comparison, it takes as much as 4,000 volts for a person to even feel the zap of a static discharge.
There are several ways for a person to become statically charged. The most common methods of charging are by friction and by induction. An example of charging by friction is a person sliding across a car seat.
Charging by induction occurs when a person with well insulated shoes stands near a highly charged object and momentarily touches ground. Charges of the same polarity are drained off leaving the person highly charged with the opposite polarity. Static charges can cause damage, therefore, it is important to use care when handling and testing electronic components.
Notice: To prevent possible Electrostatic Discharge damage, follow these guidelines:
^ Do not touch the control module connector pins or soldered components on the control module circuit board.
^ Do not touch the Knock Sensor (KS) module component leads.
^ Do not open the replacement part package until the part is ready to be installed.
^ Before removing the part from the package, ground the package to a known good ground on the vehicle.
^ If the part has been handled while sliding across the seat, or while sitting down from a standing position, or while walking a distance, touch a known good ground before installing the part.
Notice: To prevent internal [1][2]PCM damage, the ignition must be in the "OFF" position in order to disconnect or reconnect power to the PCM (for example: battery cable, PCM pigtail, PCM fuse, jumper cables, etc.).
Important: When replacing the production [1][2]PCM with a service PCM, it is important to transfer the broadcast code and production PCM number to the service PCM label. This will allow positive identification of PCM parts throughout the service life of the vehicle. Do not record this information on the PCM metal cover.
Important: The ignition should always be in the "OFF" position in order to install or remove the [1][2]PCM connectors.
Service of the [1][2]PCM should normally consist of either replacement of the PCM or EEPROM programming. If the diagnostic procedures call for the PCM to be replaced, the PCM should be checked first to ensure it is the correct part. It it is, remove the faulty PCM and install the new service PCM.
The service [1][2]PCM EEPROM will not be programmed. DTC PO6Ol indicates the check sum error.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
