SOLVED: temporarily turn off the Daytime Running Lamps (DRL) on the 2002 Chevrolet Avalanche

You want to turn off the Daytime Running Lamps (DRL) on your 2002 Avalanche.

Quoting

From the manual, page 2-55.

When necessary, you may turn off the automatic headlamp system and the DRL feature by following these steps:

  1. Turn the ignition to RUN.
  2. Press the DOME OVERRIDE button four times within six seconds. After the fourth press of the
    button, a chime will sound informing you the system is off. The system will revert back to the automatic mode when the ignition is turned off and on again.
  3. To return to the automatic mode, push the DOME OVERRIDE button four times within six seconds (the chime will sound), or turn the ignition off and on again.

And separately

The DRL system will come on when the following conditions are met:

  • the ignition is on,
  • the headlamp switch is in automatic headlamp mode,
  • the automatic transmission is not in PARK (P),
  • the light sensor determines it is daytime and
  • the parking brake is released.

When the DRL are on, only your DRL lamps will be on. The taillamps, sidemarker and other lamps won’t be on. The instrument panel won’t be lit up either.

SOLVED: reset the oil life warning on the 2002 Chevrolet Avalanche

Frequently after an oil change, the oil light will go on.  This is because the service procedure did not include resetting the lifetime timer.  This occurs at JiffyLube frequently; recently it occurred after a dealer-delivered GM megaservice at 86K miles.  Pesky.

Procedure

  1. Truck is off.
  2. Insert key
  3. Turn to on/run (do not start the engine)
  4. Push the accelerator pedal to the floor 3 times within 5 seconds.
  5. See the warning blink for 5 seconds.
  6. Key off.

Quoting

From the manual, page 6-17:

To reset the CHANGE ENGINE OIL message, do the following:

  1. Turn the ignition key to RUN with the engine off.
  2. Fully press and release the accelerator pedal three times within five seconds.
  3. If the CHANGE ENGINE OIL message flashes for five seconds, the system is reset.

If the system does not reset, try the procedure once again. If it still does not reset, see your dealer for service.

Folklore, Confusion & Disinformation

Subaru Legacy 1997 | Lights flash after battery replacement or drain/recharge cycle

Subaru Legacy GTX 1997

  • You replace the battery
  • Your battery drains to zero or beyond

Upon battery replacement, the blinker lights flash on and off.  Similar to the hazard lights, but slower.

Remediation

  • Recipe 1 [unverified]
    • Run a lock/unlock cycle with the keyfob remote.
  • Recipe 2
    1. Engine off
    2. Remove the negative terminal of the battery
    3. Key in the ignition, turn key to “position 3″ just before ignition
    4. Reconnect the negative terminal of the battery
      There must be 20 seconds between Steps 2 and 4.
    5. Lights are not flashing,
  • Recipe 3 [unverified]
    • Something incomprehensible about flipping the ignition key into “position 3″ (on and off) five times in a single second.

I used Recipe 2
