Diagnostic Aids
PINPOINT TESTS A through F are intended to diagnose hard faults. Intermittent failures may be difficult to diagnose using these procedures.
A Breakout Box (BOB) connected to DIS diagnostic cable is referred to as DIS BOB. If a second BOB is connected to the ECA vehicle harness connector it is referred to as ECA BOB. This test setup allows testing of DIS components and vehicle harness circuits.
Circuits are identified in all capitals, example: IGND=Ignition Ground. Manufacturer's BOB overlay identification is in brackets, example: (J2)=IGND (J2). This indicates test terminal number or circuit identification number.
NOTE:
Unless specified otherwise in a specific test step, all voltage and resistance tests of DIS ignition system are performed at the BOB connected to the DIS diagnostic cable.
NOTE:
When performing PINPOINT TEST procedures for the 2.3L DIS (Ranger) system, refer to Fig 1 and Fig 2.
