Does the 2003 trailblazer have a on board diagnostic system? if so how do i activate it


yes, it's always active. A light will come on when it detects a fault. You can also use a good scanner to interrogate the system, actuate valves, etc.

Please see my tip at http://www.fixya.com/cars/r5932051-check_engine_light_check and let me know if you have questions.

What has to be done to turn off sevice engine soon light ? THIS IS ON A 2003 CHEVY TRAILBLAZER.


You can buy a hand scan tool and turn it off. If you can't get a scan tool, you can remove one of the battery cables and wait for 10 mins before hooking it back up. But keep in mind that you need to reset the radio and clock

03 mercury mountaineer, service engine soon light came on. i was told it needed a oil change . we did that , now how do i get the light to go off ?


Your Service Engine Soon light has nothing to do with reminding you to change your oil. The light is controlled by the ECM (Computer) in your vehicle. It monitors various sensors in your engine and compares them to variables or programs that is in its memory. When something is not registering correctly or is outside of its parameters it will turn on a MIL(Malfunction Indicator Light)or in your case a Service Engine Soon light. You will need a OBD II ( On Board Diagnostic) reader or scanner to hook up to your diagnostic port under your driver's side footwell to read what code the ECM is putting out. Than with the code the mechanic can look up the code to see what part is sending a malfunctioning. The scanner can also read and erase the code too. You can have your code pulled up with a OBD II scanner for free from any AutoZone store.

TSB#05-06-02-012B: Service Engine Soon (SES) or Check Engine Light On, DTC P0480, P0526/P1481/P1484 Set (Replace Engine Cooling Fan Wiring Harness) - (Oct 19, 2006)
Subject:
Service Engine Soon (SES) or Check Engine Light On,
DTC P0480/P0526/P1481/P1484 Set (Replace Engine Cooling Fan Wiring Harness)
Condition
Some customers may comment that the Service Engine Soon (SES) or Check Engine light is illuminated. This condition may be intermittent and upon investigation, the technician may find either DTC P0480, P0526, P1481 or P1484 set.

Cause
This condition may be caused by the cooling fan harness chaffing against the plastic guide it routes through. This
contact may damage the insulation of the wires enclosed in that harness.

Correction
Replace the engine cooling fan harness using the procedure listed below.

1. Remove the cooling fan. Refer to the Cooling Fan and Shroud Replacement procedure in the Engine Cooling sub-section of SI.

2. Place the cooling fan assembly on a bench.
Disconnect the harness electrical connector from the cooling fan clutch.

3. Remove the harness from the plastic guide while feeding the wires out of the slot.

4. Before installing the new harness, wrap the affected area on the wires with electrical tape to keep the protective sleeve in place. Be sure to keep the tape approximately 25 mm (1 in) away from the connector so the wires can be fed into the slot.

5. Feed the wires into the slot and install the harness to the plastic guide.

6. Connect the harness electrical connector to the cooling fan clutch.

7. Install the cooling fan. Refer to the Cooling Fan and Shroud Replacement procedure in the Engine Cooling sub-section of SI.

2003 chevy trailblazer....idlind at 600-750 rpms, when i engage the a/c it drops to 500rpms then stalls. also have two codes, p1481 and p1482. whats wrong?


The coolant fan clutch or the electric connections to the fan clutch is code1482.

Code 1481 is associated with the coolant fan problem but concerns the PCM having an error.

This error is why your car is stalling. The fan clutch is variable. When it is fully engaged the fan has more resistance and pulls down the rpm. The PCM is suppose to respond to this and raise the rpm for a steady idle. It is not doing it and needs a software upgrade.

The Chevy dealer may have a service note on this problem. The upgrade may be free.

Mitsubishi Outlander 2003 Service Engine Soon


You'll need to know why the service engine light comes on, they can check this by using a OBD II diagnostic tool to find the trouble code stored in the pcm, ask them to run a check on it, or you can take it to a mechanic before you buy it to have them check over the vehicle for any minor or major problems.
