COUPLER COMPONENT INSPECTION [AY6A-EL, AY6AX-EL]

id0517k3299100

  Caution
  • Water or foreign objects entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign objects on the connector when disconnecting it.
  • Do not damage the terminals.

On-Vehicle Inspection

1. Disconnect the negative battery cable.

2. Remove the fresh-air duct and air cleaner component as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

3. Remove the TCM. (See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)

4. Measure the coupler component continuity.
