Fuel Injection and Ignition Diagnostic Procedures in Earlier Bosch LH-Jetronic 2.2, EZK 102/115/117/118 for B280/B200/B230FT.

* Using test diode #5280, connect the LED to the test terminal (yellow/red lead, usually by left front wheel well), and the red lead to the positive battery terminal.
* Turn ignition on, do not start car. LED should be illuminated
* Start car.

B23FT (EZ-102K): Rev engine past 3000 RPM (light should turn off) and allow it to idle around 1000 RPM. Watch for flashes.

B200E, B230 E/F/K, B280 E/F (EZ-118K, EZ-117K, EZ-115K): Slowly rev engine past 700 RPM (B280) or 920 RPM (others). Light should turn off. Drive car (high and low load conditions). Then, quickly rev engine past 2500 RPM (to check the knock sensors, B280). Make sure to reach full throttle, and to rev past 3150 RPM (B200/B230). Watch for flashes for at least three minutes.

EZ-102K codes:


* 1 flash: Maximum timing retardation reached (9.8 degrees)
* 2 flashes: Low battery voltage
* 3 flashes: Fault in control unit (knock sensor circuit), replace ICU.
* 4 flashes: Fault in knock sensor or wiring.
* 5 flashes: Faulty load signal from fuel injection ECU

EZ-115K codes:


* 1 flash: Knock occurred
* 2 flashes: Faulty signal from temperature sensor
* 3 flashes: ---
* 4 flashes: Faulty signal from knock sensors, or ICU knock detection circuit faulty
* 5 flashes: Faulty signal from #1 cylinder detector (#1 spark plug lead)

EZ-117/118K codes:


* 1 flash: Maximum timing retardation reached under full throttle acceleration
* 2 flashes: Temperature sensor fault (B230K only)
* 3 flashes: Maximum timing retardation reached at idle or > 3150 RPM
* 4 flashes: Faulty load signal from fuel injection ECU (engine at part load, not idling)
* 5 flashes: Insufficient advance at idle (B200E/B230E/B230K only)
* 6 flashes: Insufficient advance (B230K only)

To make the number 1 cylinder sensor and flywheel sensor you need the following parts:

* 4 meters of single core wire;
* one crocodile clip (for positive terminal);
* one male flat spade connector (for inserting into female connector located close to left hand front strut ;
* one ~.25w LED (light emitting diode) [Note] The Radio Shack 12V LED with 30mA/80mcd should work fine without the resistor below.
* resistor 560 ohms +/- 5% (green, blue, brown, gold bands on a four-band resistor)

Assembly:

1. Cut 4 meter cable into 2 equal length pieces
2. Solder one length of cable to negative connector on LED
3. Attach spade connector to end of cable soldered to negative LED connector
4. Solder resistor to positive LED connector.
5. Solder remaining electrical cable to other resistor leg.
6. Attach crocodile clip to other end of cable connected to resister
7. Cover whole of LED, resistor etc. with insulating tape, leaving gap to see LED flash etc.

To use (see the attached diagram):

1. attach crocodile clip to positive of battery terminal
2. attach spade connector
3. feed LED display through into passenger compartment so that can be observed whilst driving
4. close bonnet and start engine

If there are any problems the LED will flash the following codes

* 1 flash - Engine knock has occurred, activating knock-controlled timing retardation. Can be due to inferior grade fuel, excessive engine temperature, faulty plug, intake system leakage or engine carbonization (due to frequent cold start and idling).

* 2 flashes - Faulty signal from temperature sensor
* 3 flashes - not used
* 4 flashes - Faulty signal from knock sensors or faulty knock detection circuit (internal to control unit).
* 5 flashes - Faulty load signal from fuel system control unit
* 6 flashes - Faulty signal from No 1 cylinder detector

The unit will flash out the code, then there will be a noticeable delay, when it will flash the code again. Some of the codes will only be flashed under load, so if you get no code at idle, take the car for a drive, accelerating etc. The attached drawing shows sensor connection.
