Jeep Grand Cherokee 2000 3.1L t/diesel a/t иммобилайзер

Здравствуйте.

Родной ECU в плохом состоянии .Есть донор , но на нем не заводится ,т.к. присутствует иммо. Достаточно ли будет переставить EEPROM от родного в новый (фото №1) ? Лишний раз греть не хочу , плата какая то уж очень нежная. Что за EEPROMка такая какой ее аналог , если читать?

Что такое на первом фото я не знаю, но судя по подключению это не еепром, а иммошник у тебя по ходу во влэши прописан, её надо перепаивать.

Спасибо ,тоже к этому склоняюсь.

Имейте ввиду, что там еще один блок управления живет. Бошевский под задним сиденьем. Он двигателем и заведует.

Вот описание того, какой блок за что отвечает.

Может пригодится вам в работе

 

ESCRIPTION AND OPERATION (Continued)

When the Check Engine Lamp is illuminated con- stantly with the key on and the engine running,, it usually indicates a problem has been detected some- where within the fuel system. The DRBIII scan tool is the best method for communicating with the ECM and PCM to diagnose faults within the system.

POWERTRAIN CONTROL MODULE (PCM) AND

ENGINE CONTROL MODULE (ECM)

The Engine Control Module (ECM) is mounted underneath the left rear seat. The Powertrain Con- trol Module (PCM) is mounted in the engine com- partment.

The ECM Controller is a pre–programmed, digital computer. It will either directly operate or partially regulate the:

• Speed Control
• Speed Control lamp
• Fuel Timing Solenoid
• Check Engine Light
• Glow Plug Relay
• Glow Plugs
• Glow Plug Lamp
• ASD Relay
• Air Conditioning
• Tachometer
• Electric Vacuum Modulator (EVM)
The ECM can adapt its programming to meet

changing operating conditions.
The ECM receives input signals from various

switches and sensors. Based on these inputs, the ECM regulates various engine and vehicle operations through different system components. These compo- nents are referred to as ECM Outputs. The sensors and switches that provide inputs to the ECM are considered ECM Inputs.

ECM Inputs are:

• Air Conditioning Selection
• Theft Alarm
• ASD Relay
• Control Sleeve Position Sensor • Fuel Temperature Sensor

• Mass Air Flow Sensor
• Accelerator Pedal Position Sensor
• Engine Coolant Temperature Sensor
• Low Idle Position Switch
• 5 Volt Supply
• Vehicle Speed Sensor
• Engine Speed/Crank Position Sensor (rpm) • Needle Movement Sensor
• Starter Signal
• Brake Switch
• Speed Control Switch
• Power Ground
• Ignition (key) Switch Sense
ECM Outputs:

WJ

After inputs are received by the ECM and PCM, certain sensors, switches and components are con- trolled or regulated by the ECM and PCM. These are considered ECM Outputs. These outputs are for:

• A/C Clutch Relay (for A/C clutch operation) • Speed Control Lamp
• ASD Relay
• 5 Volts Supply

• Fuel Quantity Actuator • Fuel Timing Solenoid
• Fuel Shutdown Solenoid • Glow Plug Lamp

• Check Engine Lamp (“On/Off” signal) • Electric Vacuum Modulator (EVM)
• Glow Plug Relay
• Tachometer

The PCM sends and receives signals to and from the ECM controller. PCM inputs are:

• Power Ground
• 5 Volts Supply
• Vehicle Speed Sensor
• Water-In-Fuel Sensor
• Coolant Temperature Sensor
• Low Coolant Sensor
• Sensor Return
• Fuel Level Sensor
• Oil Pressure Sensor
• Tachometer Signal
• Glow Plug Lamp
• Check Engine Lamp (“On/Off” signal)
• Brake On/Off Switch
• Battery Voltage
• ASD Relay
PCM Outputs:
• A/C On Signal
• Vehicle Theft Alarm “Ok to Run” signal • Body Control Module CCD Bus (+)
• Body Control Module CCD Bus (–)
• Scan Tool Data Link Receive
• Scan Tool Data Link Transmit
• Low Coolant Lamp
• Generator Control
