MODELS 

2016–2020 MDX (except Hybrid)

2022–2023 MDX (except Type S)

2015–2020 TLX V6

CONDITION

The engine will not crank on the initial startup attempt after the vehicle has been exposed to precipitation and then freezing temperatures.

POSSIBLE CAUSE

Water can enter the starter motor. In cold temperatures, the water can freeze, preventing the starter motor from cranking the engine.

CORRECTIVE ACTION

Replace the starter motor assembly, if needed.

INSPECTION PROCEDURE

  1. Confirm that the engine does not crank.
  2. Inspect the starter motor for signs of icing. If icing is found, warm up the starter motor either by gently applying heat or allowing the vehicle to thaw inside the shop environment.
  3. After the thawing period, attempt to crank/start the engine.

If the engine starts, replace the starter.

If the engine doesn’t crank/start, continue with normal troubleshooting.

TIPS

-Using a scan tool, reset the Idle Stop Starter Counter.

-To protect the battery sensor connector from damage, do not hold it when removing the negative terminal.

PCV systems control crankcase pressure.

The PCV system helps to keep the pressure inside of the crankcase within a certain range. Blowby gasses are generated by the pistons moving up and down inside the cylinders. Automakers have come up with a number of solutions to control crankcase pressure. We’ve come a long way from the days of small, inexpensive PCV valves which were a regular maintenance item. Nowadays, PCV systems are far more complex, but they are also much better at controlling crankcase pressure.
