Disconnect battery on 2003 nissan micra auto to clean and grease terminal, when reconnected car wont start all lights are on but wont turnover. Car was working perfect prior to disconnecting battery.

Just because lights are working does not mean you have a good enough connection to operate the starter motor. Try turning on headlamps, then try to crank it with someone looking at headlamps. If they dim badly or go out, recheck the battery terminal connections. Did you grease the areas that should make the connections? What grease did you use? Try cleaning connections with brake cleaner, sand or wire brush and reconnect without grease. If this works, grease the outside only to seal connections and prevent corrosion.

How do you get car out of safe mode

Try disconnecting the battery for 2 hours and after disconnecting push the brake pedal to discharge any remaining capacitance (charge).
Once reconnected it should be back to normal, if it is not you will need a Nissan consult scanner to reset it.

My x5 3.0i 2006 t won't start this morning but temperature, gas level clock were wrong so I turn the engine off and restart a couple times it won't start and I saw message trans. false safe...

no. I'd suggest to disconnect a battery for 15 mins, reconnect, wait for 5 mins and try to restart. If it doesn't help (sometimes there's a program block to prevent stealing equipment) call a dealer

cb88b61.jpg Fig. Fig. 4: Exploded view of the starter motor mounting-2.0L engine
To install:
  1. Clean both surfaces of the starter motor flange and the rear plate. This is important since the starter grounds through its case and the transaxle flange to which it attached. Some remanufactured starters may have paint on these areas which should be cleaned off before installation. Install the starter motor onto the transaxle and secure with the retaining bolts. Tighten the bolts to 40 ft. lbs. (54 Nm).
  2. Attach the electrical harness connectors to the starter.
  3. Connect the negative battery cable and check the starter for proper operation.

2.0L SOHC Engine With Manual Transaxle
See Figures 4 and 5
  1. Disconnect the negative battery cable from the left strut tower. The ground cable is equipped with a insulator grommet which should be placed on the stud to prevent the negative battery cable from accidentally grounding.
  2. Remove the air cleaner resonator.
  3. Remove the positive battery cable retaining nut from the starter.
  4. Disconnect the positive battery cable and alternator output wire from the starter.
  5. Disconnect the push-on solenoid connector from the starter.
  6. Remove the 2 bolts that attach the starter to the transaxle.
  7. Remove the starter from the vehicle.

  1. Install the starter and the attaching bolts to the transaxle assembly.
  2. Tighten the attaching bolts to 40 ft. lbs. (54 Nm).

Clean all dirt and/or corrosion from the wire terminals before reconnecting the wiring to the solenoid.
  1. Reconnect the push-on solenoid connector to the starter.
  2. Reconnect the alternator output wire and positive battery cable to the starter and tighten the retaining nut to 90 inch lbs. (10 Nm).
  3. Install the air cleaner resonator.
  4. Reconnect the negative battery cable.

2.0L SOHC Engine With Automatic Transaxle; 2.4L Engine
See Figures 4, 5 and 6
  1. Disconnect the negative battery cable from the left strut tower. The ground cable is equipped with a insulator grommet which should be placed on the stud to prevent the negative battery cable from accidentally grounding.
  2. Remove the air cleaner resonator.
  3. Remove the 3 bolts attaching the Transmission Control Module (TCM). Do not disconnect the TCM wiring. Move the TCM to gain access to the upper starter mounting bolt.
  4. Remove the upper starter mounting bolt.
  5. Raise and safely support the vehicle.
  6. Remove the positive battery cable nut and disconnect the cable from the starter.
  7. Disconnect the push-on solenoid connector.
  8. Remove the lower mounting bolt that attaches the starter to the transaxle.
  9. Remove the starter from the vehicle.

  2. Reconnect the push-on solenoid connector.
  3. Lower the vehicle.
  4. Reinstall the upper attaching bolt and torque to 40 ft. lbs. (54 Nm).

What does hdc inactive air suspension inactive trans safe failure mean car will not stay started

This error could be casued by a poor battery - particularly in cold weather. If you suspect your battery may be in poor condition, try recharging it over night.

The error can also be caused by a worn suspension compressor.

You could visit a Land Rover dealership or if you wish to save yourself the heavy costs you could visit an independent workshop who can check your car's memory log which may provide further information regarding the fault.

Check www.rangerovers.net for further information.

The "Service!" message keeps appearing but the car was just serviced as I just bought it certified pre-owned Audi from a dealer

Try this, disconnect the negative battery cable from the battery, wait 10 to 20 minutes, and reconnect. maybe , maybe not. but worth a try

Hi.. i have a 2004 range rover and on the message center it tell me that the air suspension is inactive, hdc is inactive as well as selflevel air suspension is inactive... is there any way i can...

The EAS can have many different faults that will give the same warning. I have had several air susp problems. First try to disconnect the battery, wait several minutes reconnect then drive car making at least on full circle. If lights remain, air pump (under spare tire ) can be checked, also valve under a cover behind right front wheel, other than these areas, the Testbook diagnostic at dealer will determine if any other parts are source of problem. Unfortunately, with the complexity of the system many other parts Height sensors, etc, etc can also cause the error message. Good Luck.
