Component Testing

With Special Tool

NOTE:

Circuit/System Testing must be performed before proceeding with Component Testing.

1. Ignition/Vehicle - Off
2. Remove the appropriate component: T8 Ignition Coil - Leave the electrical connector connected.
3. Install the special tool: J-26792 Ignition Spark Tester
4. Engine - Running
NOTE:

     Test or replace the component: T8 Ignition Coil

   • Go to next step: If there is spark 
6. All OK.

Without Special Tool

1. Ignition/Vehicle - Off
2. Swap the two components: T8 Ignition Coil - The original component that set the DTC & Another known good component from the vehicle
3. Engine - Running
4. Verify the scan tool parameter: Cylinder 1 - 4 Current Misfire Counter = Increments - At the original component location the DTC set.
   • If the parameter value does not increment 

     Replace the component: T8 Ignition Coil - The original component that set the DTC

   • Go to next step: If the parameter value increments
