Test A: The Engine Does Not Crank

PINPOINT TEST A: THE ENGINE DOES NOT CRANK

Normal Operation
Under normal operation, constant power is supplied to the starter relay on circuit SBB02 (YE/RD), the starter on circuit SDC02 (RD) and to the ignition switch on circuit SBB14 (BN/RD). When the key is placed in the START position, with the vehicle in PARK or NEUTRAL or with the clutch pedal depressed, power is supplied to the smart junction box (SJB) on circuit CDC36 (GN/WH) to the starter relay. Inputs from the transmission range (TR) sensor and clutch cutoff switch to the PCM provide a ground to the starter relay on circuit CDC12 (YE). When the coil of the relay is energized, it sends power to the starter motor on circuit CDC25 (BN/GN).

This pinpoint test is intended to diagnose the following:
- Battery
- Fuse(s)
- Ignition switch
- Starter motor relay - non-serviceable (part of SJB)
- PCM
- Anti-theft system
- Circuitry
