How are you doing it ? Transmitter Programming Important: All transmitters that are to be recognized by the remote control door lock receiver (RCDLR) must be programmed in a single programming sequence. If the system is placed in program mode, all previously programmed transmitters will be erased upon receipt of the programming signal from the first transmitter. Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle. The order in which the transmitters are programmed is important. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. Use care to program the transmitters correctly. The scan tool must stay connected until all of the transmitters are programmed. Install a scan tool. Turn ON the ignition with the engine OFF. With the scan tool, select Body, go to Remote Function Actuation. Select Special Functions. Select Program Key Fobs. Select the number of key fobs to be programmed. Press and hold the LOCK and the UNLOCK buttons simultaneously on the first transmitter for approximately 15 seconds. The power locks should cycle to confirm programming of the first fob is complete. If you are programming more than one transmitter, repeat the previous step to program up to 4 transmitters. Remove the scan tool. Exit the vehicle. Attempt to lock/unlock the doors to verify the programming. Operate the transmitter functions in order to verify correct system operation. DEALER !

Make sure the antifreez is toped up in the radiator BUT only open when the engine is cold, like in the morning, on the other hand if the tempreature sensor is cracked, you will have the same symptoms. When was the tune up done? Let me know how you make out.

Getting the timing chain back on these engines can be tricky and requires more than just a diagram to get right. Here is how the timing chain should be reinstalled. Keep in mind that this engine can cause damage to the valves if the timing chain has any problems while the engine is running so it may not be a bad idea to setup the timing system as follows and do a compression test to make sure that everything is in order there.
Install the crankshaft sprocket with timing mark at the 5 o'clock position. Lower the timing chain through the opening in the top of the cylinder head. Carefully ensure that the chain goes around both sides of the cylinder block bosses (See 1 & 2 in picture): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412535.gif

Install the intake camshaft sprocket with the INT diamond at the 2 o'clock position. Hand tighten a NEW intake camshaft sprocket bolt. Route the timing chain around the crankshaft sprocket with the matching colored link aligning with the timing mark. Route the timing chain around the intake camshaft sprocket with the uniquely colored link (1) aligning with the INT diamond: http://gsi.xw.gm.com/image_en_us/gif/000/000/466/466558.gif

Install the timing chain tensioner guide through the opening in the top of the cylinder head. Tighten the timing chain tensioner guide bolt to 10 N·m (89 lb in): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412160.gif

Install the exhaust camshaft sprocket with the timing chain matching colored link (3) at EXH triangle aligned at the 10 o'clock position: http://gsi.xw.gm.com/image_en_us/gif/000/000/466/466570.gif

Ensure the timing marks and the colored links (1,2,3) are correctly aligned: http://gsi.xw.gm.com/image_en_us/gif/000/002/003/2003412.gif

Use a 24 mm wrench to rotate the camshaft slightly, until exhaust sprocket aligns with the camshaft. Hand tighten the NEW exhaust camshaft sprocket bolt: http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412536.gif

Install the fixed timing chain guide. Tighten the fixed timing chain bolts to 10 N·m (89 lb in): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412165.gif

Apply sealant, GM P/N 12378521 (Canadian P/N 88901148) compound to thread and install the timing chain guide bolt access hole plug. Tighten the chain guide plug to 90 N·m (66 lb ft): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412164.gif

Install the timing chain upper guide. Tighten the timing chain upper guide bolts to 10 N·m (89 lb in): http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412167.gif

Inspect the timing chain tensioner. If the timing chain tensioner, O-ring seal, or washer is damaged, replace the timing chain tensioner. Measure the timing chain tensioner assembly from end to end. A new tensioner should be supplied in the fully compressed non-active state. A tensioner in the compressed state will measure 72 mm (2.83 in) (a) from end to end. A tensioner in the active state will measure 85 mm (3.35 in) (a) from end to end.

****If the timing chain tensioner is not in the compressed state, perform the following steps. Remove the piston assembly from the body of the timing chain tensioner by pulling it out. Set the J 45027-2 (2) into a vise. Install the notch end of the piston assembly into the J 45027-2 (2). Using the J 45027-1 (1), turn the ratchet cylinder into the piston: http://gsi.xw.gm.com/image_en_us/gif/000/000/797/797246.gif

Inspect the bore of the tensioner body for dirt, debris, and damage. If any damage appears, replace the tensioner. Clean dirt or debris out with a lint free cloth. Install the compressed piston assembly back into the timing chain tensioner body until it stops at the bottom of the bore. Do not compress the piston assembly against the bottom of the bore. If the piston assembly is compressed against the bottom of the bore, it will activate the tensioner, which will then need to be reset again. At this point the tensioner should measure approximately 72 mm (2.83 in) (a) from end to end. If the tensioner does not read 72 mm (2.83 in) (a) from end to end repeat the steps required to return it to it's compressed state above.

Install the timing chain tensioner. Tighten the timing chain tensioner to 75 N·m (55 lb ft). Use a suitable tool with a rubber tip on the end. Feed the tool down through the camshaft drive chant to rest on the timing chain. Then give a sharp jolt diagonally downwards to release the tensioner: http://gsi.xw.gm.com/image_en_us/gif/000/000/412/412158.gif

Use a 24 mm wrench to hold the camshaft. Tighten the NEW camshaft bolts to 85 N·m (63 lb ft) plus 30 degrees: http://gsi.xw.gm.com/image_en_us/gif/000/000/630/630311.gif

Hi. On the back side of the transmission, opposite end from engine, about half way up, there you will find the VSS output sensor, near the CV axle. The VSS input sensor is on the same side but at the halfway point or in the middle of the back side. Hope this helps.

All of the shafts have a specific relationship to each other its controls ware the pistons and valves are when the engine fires TIMING . You need to find T.D.C top dead center on #1 cylinder so its at the top of its stroke in compression stroke then redo what you have just done and it will work .

I recently tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. It would'nt move forward or reverse, engine was good both solenoids for forward and reverse worked, but still couldn't diagnose the problem. I don't have much technical knowledge but I just followed it step-wise, and now it works perfect! covers wiring, diagrams, torque specs, PCV, everything got it from www.reliable-store.com

Most likely that one of the ABS Wheel Sensors is disconnected or got damaged during repairs that you made. Check connectors for ABS wheel sensors at front brakes. If look ok, you need to check computer codes to know which sensor is damaged and replace sensor.

Not a fuse problem , same fuse power's low an high beams . Looking at wiring diagrams an using a DVOM - digital volt ohm meter to test the electrical circuit's is the way to find the problem . The light's staying on for 3 or 4 min's. is a function of the BCM - body control module ! Do you know anything about automotive electrical testing ? Do you know what a wiring diagram is an how to read one . Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. Year , make , model an engine size . Under system click on lighting ,then under subsystem click on headlamps .Click the search button then the blue link. get yourself a cheap DVOM an test the electrical circuit's , this is how electrical problems are solved . Electric Testing Techniques You Need to Know Basic Electricity for Service Techs Ohm law Current Flow Opens Shorts Plus reading factory service repair info for how it should work would be a good idea . Headlamps The headlamps may be turned on two different ways. First, when the driver places the headlamp switch in the HEADLAMP position, for normal operation. Second, with the headlamp switch placed in the OFF position, for automatic lamp control (ALC). During ALC, the headlamps will be in day time running lamp (DRL) operation in daylight conditions, or low beam operation in low light conditions. The LH HDLPand RH HDLP fuses, supply battery positive voltage from the underhood junction block to the left and right headlamps. The circuit continues through both low and high beam lamps, then back to the underhood junction block. The low beam and high beam circuits continue to the headlamp switch. The low beam and high beam circuits also provide the body control module (BCM) with both low and high beam inputs. The headlamp switch includes the dimmer switch and the flash-to-pass switch. When the headlamp switch is placed in the HEADLAMP position a path to ground is provided. Ground is provided at G201. Depending on the position of the high/low beam switch, either the low or high beam circuit will now have power and ground. The LH HDLP fuse in the underhood junction block, supplies battery positive voltage to the automatic lamp control (ALC) headlamp relay coil circuit. The ALC relay switch circuit is connected to the low beam circuit at the headlamp switch. When the headlamp switch is placed in the OFF position, the BCM will automatically turn on the low beams in low light conditions. The BCM energizes the ALC relay, closing the switch contacts and grounding the low beam circuit. Ground is provided at G201. With the headlights in the low beam position, the high beams may be momentarily turned on or flashed with the dimmer switch handle. The flash-to-pass feature is accomplished by pulling the dimmer switch handle toward the driver. The headlights may be switched to high beam with the opposite movement of the dimmer switch lever. When the headlamp dimmer switch handle is pulled toward the driver, the flash-to-pass switch closes grounding the high beam circuit. Ground is provided at G201. Both high beams will remain on until the driver releases the switch handle. If the driver places the headlight switch in the HEADLAMP position , the headlights will remain on until turned off or the battery runs dead. Do you know what a factory diagnostic trouble shooting chart is ? Headlamps Inoperative - Low Beams Step Action Yes No Schematic Reference: Headlights/Daytime Running Lights (DRL) Schematics 1 Did you perform the Lighting System Diagnostic System Check? YES - Go to Step 2 NO - Go to Diagnostic System Check - Lighting Systems 2 Place the headlamp switch in the HEADLAMP position. Place the headlamp dimmer switch in the LOW position. Do the low beam headlamps illuminate? YES - Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems NO - Go to Step 3 3 Disconnect the turn/headlamp wiper switch assembly connector C2. Connect a 15 amp fused jumper between the headlamp low beam signal circuit and a good ground. Do the low beam headlamps illuminate? YES - Go to Step 4 NO - Go to Step 5 4 Inspect for poor connections at the harness connector of the turn/headlamp wiper switch assembly. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? YES - Go to Step 7 NO - Go to Step 6 5 Repair an open or high resistance in the headlamp low beam signal circuit. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. YES - Did you complete the repair? NO - Go to Step 7 -- 6 Replace the turn/headlamp wiper switch assembly. Refer to Multifunction Turn Signal Lever Replacement - On Vehicle in Steering Wheel and Column. Did you complete the replacement? Go to Step 7 -- 7 Operate the system in order to verify the repair. Did you correct the condition? YES - System OK NO - Go to Step 3
