Hi All Sportrak owners new and old.

I thought I'd re-post this item as I have had a number of contacts relating to starting problems.

Diagnostics
Submitted by oldminiman on Mon, 30/07/2007 - 20:53.
THIS IS AN EXTRACT FROM THE OFFICIAL SPORTRAK MANUAL. I CANNOT BE HELD RESPONSIBLE FOR ANY USE OF THIS THAT MAY RESULT IN ANY DAMAGE BUT I HAVE WRITTEN IT DIRECT FROM THE MANUAL.

The diagnostic plug is on the right handside of the bulkhead and on mine is green in colour. The black spots are rubber bungs which can be removed.

Remove the two front bungs from the right side in on the front row. The furthest right is the test terminal and the next is ground. Place a wire between the two. I usually use ring main wire as it can be shaped and plugs in easier.

Set the ignition to on but do not start the engine. The check engine light will flash a number of times indicating the fault.

eg 1 flash of about 0.5 seconds 4.5 seconds after the key has been switched on indicates no fault. The light will flash again after 4.5 seconds. This then will be the pattern repeated by all the faults.

When a single malfunction occurs the engine check lamp will flash a number of times for 0.5 seconds 4.5 seconds after the key is switched on and then repeat the flashes after a further 4.5 seconds.

When a number of faults are detected the same will occur but the next malfuntion code will flash after 2.5 seconds. So you get one malfuntion as above , a second after 2.5 seconds and so on. Once all are flashed it will repeat them again after 4.5 seconds.

To cancel a diagnosis code disconnect the battery earth cable (-) for at least 10 seconds with the ignition switched off. Ambient temperature should be 20C

Codes:
1 flash normal
2 flashes Pressure sensor - check pressure sensor, circuit
3 flashes Ignition signal - No signal from Ignition- check Disi, ignitor, coil, leads.
4 flashes Water Temperature sensor -check Water temp. sensor and circuit.
5 flashes Oxygen sensor - check sensor and circuit
6 N/A
7 flashes Throttle position sensor when both idle and power switch enter "on" - check Throttle sensor and circuit.
8 flashes Intake Air temp Sensor deviation from values -check Intake Air temp Sensor and circuit.
9 flashes Vehicle speed sensor No signal input from sensor - check vehicl speed sensor and circuit.
10 flashes Starter signal Failure to input starter signal. Note this may occur and memorised if the car is bump started. - Check starter and circuit
11 flashes Switch signal When even one of the following conditions is satified with the test terminal shorted with the Ground terminal: A) air conditioning funtioning
when idle switch is turned off
Check Air Con Syste, Throttle position sensor,and circuit.

12 flashes EGR control When judged that the EGR control system is not functioning properly. - check EGR valve Modulator, EGR VSV and water temp. sensor.

15 flashes Air to fuel mix RICH. CHECK INJECTOR CIRCUIT, INJECTOR, FUEL PRESSURE, PRESSURE REGULATOR,PRESSURE SENSOR, wATER tEMP. sENSOR AND CIRCUIT,iNTAKE AIR TEMP SENSOR AND CIRCUIT.

16 flashes Air to fuel mix WEAK. -CHECK INJECTOR CIRCUIT AND INJECTORS, ECU, FUEL PRESSURE,PRESSURE REGULATOR,PRESSURE SENSOR,WATER TEMP SENSOR AND CIRCUIT, INTAKE AIR TEMPERATURE SENSOR AND CIRCUIT.

phew. it is a translation from Japanese and is not in the best of English and against each is a reference to the Manual for the appropriate reference page in the manual ef 2 flashes = EF 172 and 147
3 = ig 15,3 & EF149,
4-EF165 & EF150
5 EF187 &151
7 EF170&152
8 EF168 & 155
8 EF168&155
9 EF156
10 EF157
11 EF170 &158
12 EF181 &165,
15 EF220;231;172;165;150;168;155.
16 EF 220;186;231;165;150;168;155.

aS YOU GO THROUGH THE CHECKS AND CORRECT WHERE NECESSARY DISCONNECT THE NEG BATTERY TERMINAL FOR 10 SECONDS AND THEN RUN THE TEST AHGAIN AND KEEP DOING SO TILL YOU GET 1 FLASH.

I hope you can make sense of this and that you can find your fault and cure it. The manual will tell you how to test the sensors, where to locate them etc.

GOOD LUCK
