HOW TO.. ADJUST THE AIR CONDITIONING/ALTERNATOR BELT.

 

Problem: when you start your car or your air conditioner, the car makes a sound like pig squealing.

Solution: your alternator belt needs adjusting.

Step 1:      The engine area where you will have to work in.

Step 2:      The bolt to loosen: make sure the engine is off, and loosen this bolt.

Step 3:      The adjusting bolt: turn it until the alternator belt is tightened.

Step 4:      Tighten the pulley bolt back up and start the engine with the air con on full.

NOTE: If the squealing noise is still there, repeat all above steps until the noise goes away. If the belt is old or worn, you will have to replace it or also spray belt dressing on the belts. This will stop it from happening again.

HOW TO.. READ MY V6 ENGINE CONTROL UNIT'S ERROR CODES.

 

Here is how to build an easy and cheap ECU error code reader for your V6 engine.

Required items: Buy 6 inches (about 16 centimeters) of insulated cable, preferably with a 2.5mm solid core and a non-flashing 12V-LED.

Step 1: Open the hood/bonnet and locate the black oblong diagnostic connector behind the battery with the word "DIAGNOSTIC" written in raised type on the top.

Step 2: Opening the black DIAGNOSTIC connector, inside the lid is a map of the pins contained within. It is possible to scope O2 sensors and various other systems from here but we will be limited to code reading here. Locate the terminals called TEN & GND. WARNING: notice there is a B+ terminal nearby which must not be touched even by strands of wire as it is a 30A feed from the battery.

Step 3: Ensure the ignition is OFF, the parking/hand-brake is applied and the gearbox is in neutral.

Step 4: Take a piece of insulated wire, around 2.5mm and strip off 1 centimeter of insulation from each end and form it into a loop. Solid wire is preferred.

Step 5: Connect this jumper-hoop across the connections labled GND & TEN. Ensure no other connectors are joined and no strands are wandering about if stranded wire is used.

Step 6: Connect the 12V-LED to the B+ terminal, and the other free end to the FEN terminal. Ensure that nothing else is connected or accidentally connected as B+ is a 30A 12V supply!!

Step 7. Turn the ignition to ON but do not start the car, watch the LED as it flashes out any codes. If it does not flash confirm the connections, if still not flash then you have no codes stored.

Step 8. Codes are flashed out according to the lowest code first, and repeated after a pause of 4 seconds. The format is akin to morse code, in that a short flashes represent 1s and longer flashes 10s. Thus flashes of -- -- - - - - would represent a code of 24 which is common around 60k miles and is the rear O2 sensor. This is the most common cause of CELs.

Step 9. To clear codes, disconnect the negative battery terminal for 2 minutes with a door left open or apply the brakes.

Step 10. Turn the Ignition to OFF before removing the leads and ensure when removing no other connections are touched.

Step 11. If more than one code is present, it can be worth clearing all codes and then checking them again to see which are reoccuring. It is not uncommon for sporadic codes to appear under certain fault conditions, before spending money on any components other than O2 sensor or TPS (code 12) codes should be confirmed.

The error codes:

CODE	DESCRIPTION
02	'NE2' crankshaft position sensor
03	'G' camshaft position sensor
04	'NE1' camshaft/crankshaft position sensor
05	Knock sensor
08	Volume Air Flow sensor (VAF)
09	Coolant temperature sensor (CTS)
10	Intake air temperature sensor (IAT)
12	Throttle position sensor (TPS)
14	Barometric pressure sensor
15	LHO2S inactivation error
16	Exhaust gas recirculation (EGR) system
17	LHO2S inversion error
23	RHO2S inactivation error
24	RHO2S inversion error
25	Fuel pressure regulator control solenoid
26	Canister purge solenoid
28	EGR vacuum solenoid
29	EGR vent solenoid
34	Idle air control (IAC) solenoid
41	VRIS #1 solenoid
46	VRIS #2 solenoid
67	LFAN relay (1993 only)
69	ECTF sensor (1993 only)
