Pre-Test Instructions

Run PINPOINT TESTS only after completing VISUAL INSPECTION  , KEY ON, ENGINE RUNNING TEST  and CONTINUOUS MONITOR TEST  .

• Each PINPOINT TEST assumes a fault has been detected. Failure to comply with correct testing order can result in error.
• Test results depend on proper operation of related parts. Correct any defects in this area before passing quick test.
• DO NOT  replace parts unless test results indicate it.
• When one or more service codes are shown, start with first code received.
• DO NOT  measure voltage or resistance at control module or connect any test lights unless specified.
• Isolate both ends of a circuit and turn ignition off whenever checking for shorts or continuity, unless specified.
• Disconnect solenoids and switches from harness before measuring for continuity, resistance or energizing with 12-volt source.
• In using pinpoint test, follow each step in order, starting from first step in appropriate test. Follow each step until fault is found.
• Unless otherwise specified, an open is defined as any resistance reading greater than 5 ohms.
• Unless otherwise specified, a short is defined as any resistance reading less than 10 k/ohms (10,000 ohms) to ground.
