Wiring Harness: Testing and Inspection
COUPLER COMPONENT INSPECTION [AY6A-EL]
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. Service and Repair
3. Remove the TCM. Service and Repair
4. Measure the coupler component continuity.
- If there is any malfunction, perform an off-vehicle inspection of coupler component.
