DOWNLOAD OBD SOCKET LOCATION GUIDE BELOW!

 

PLEASE NOTE:If after following the instructions below the Check Engine Light does not flash it either means there are no fault codes or there is a connection error. To test connection, remove the TPS and run the engine then recheck codes.

PLEASE FOLLOW THE INSTRUCTION BELOW

1 If possible run the engine to bring the oxygen sensor up to operating temperature then switch the engine off.

2 Connect the terminals using your own jumper wire.

ABOVE ARE THE JUMPER SETTING FOR MANUAL DIAGNOSTIC

3 Turn ignition ON.

4 If the Check Engine Light (CEL) flashes, read codes as described in the Code Format Description below.

Here is the code format

 Read the Check engine light on your dashboard base on code format above.

Code Format Description

• Each code is made up of two series of flashes.

• The long flashes indicate the ‘tens‘ digits.

• The short flashes indicate the ‘ones’ digits.

• A long pause separates each code sequence.

• Code Format on the diagram above is Code 12.

• If no long flashes are observed then the code is a straight count of short flashes. i.e. 4 flashes = code 4.

BELOW ARE LIST OF TROUBLE CODES.

Code	Sensor/Circuit	Cause	Solution
0	ECU	ECU Bad, or ECU Fuse Blown	Check ECU Fuse, Check Eeprom is in socket correctly and not loose
1	Oxygen Sensor	Loose Wiring, Bad Sensor	Check wiring, check sensor *
3	Map Sensor	Loose Wiring, Bad Sensor	Make sure sensor is plugged in and wiring is correct
4	CKP (Crankshaft Position Sensor)	Loose Wiring	Check that distributor plugs are connected and wiring is not loose
6	Coolant Temperature	Loose Wiring, Bad Sensor	Check that plug is connected and wiring is not loose

23	Knock Sensor	Loose Wiring, Bad Sensor	Check wiring, check sensor *
4	Oxygen Sensor Heater Circuit	Loose Wiring, Bad Sensor	Check wiring, check sensor *
43	Fuel System Supply	Low Fuel Pressure, Vacuum Leaks	Make sure fuel pressure is adequate at idle (40-50psi base), check for vacuum leaks

IF YOU DONE AND YOU ALREADY FIX THE PROBLEM YOU CAN NOW CLEAR THE CHECK ENGINE LIGHT.

PLEASE FOLLOW THE INSTRUCTION BELOW.

NOTE: IF THE CODE WAS NOT ON THE LIST ABOVE. PLEASE GOOGLE IT. THANKS

Erasing Guide

1. Erasing Switch ignition OFF.
2. Remove bridge wire. Remove BACK UP fuse (7,5A) from underbonnet fusebox for 10 seconds minimum
3. Refit fuse.
4. Trouble codes may also be erased by disconnecting battery lead. WARNING: Disconnecting BACK UP fuse or battery may erase memory from electronic units (e.g. radio, clock).
5. Repeat checking procedure to ensure no data remains in ECM fault memory.
