Acura Frozen Starter Causes No Start

Acura Frozen Starter Causes No Start

Why won't the engine crank after the vehicle has been exposed to precipitation and then freezing temperatures?

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.

How Belts, Tensioners And Misfires Are Connected

Modern crankshaft position sensors measure more than the position of the crankshaft.

Have you ever been amazed about how complex some belt routing diagrams can be when all they are driving is an alternator, A/C compressor and maybe a power steering pump? The belt might be 8-feet long and loop around one or two idler pulleys. 

On an engineering level, the design of the accessory belt drive is a balancing act of efficiency, force and vibration. The more contact or wrap a belt has with a pulley, the more force or energy can be transmitted without slipping and the less tension the belt will need. But this is not great for efficiency because it creates more friction and drag.
