Description and Operation
Control Diagram
NOTE: A = Hardwired
Item Description 1 Battery 2 Starter motor 3 EJB (starter relay) 4 ECM 5 BJB (250 A megafuse) 6 BJB (400 A megafuse)
Page 1262 of 3039
When the ECM receives a crank request, it energizes the starter relay in the EJB (engine junction box). The energized starter relay supplies 12 V power (fed via the 250 A megafuse in the BJB (battery junction box)) to energize the pull-in coil of the
starter solenoid. Once activated, the pull-in coil engages the solenoid plunger, which engages the pinion with the ring gear.
The plunger then closes the solenoid circuit, feeding power from the 400 A megafuse in the BJB to the starter motor.

Starting System - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Starting System
Diagnosis and Testing
Principles of Operation
For a detailed description of the starting system and operation, refer to the relevant Description and Operation section of the
workshop manual. REFER to: (303-06C Starting System - V8 5.0L Petrol/V8 S/C 5.0L Petrol)
Starting System (Description and Operation), Starting System (Description and Operation), Starting System (Description and Operation).
Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.
NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical and electrical damage.
Visual Inspection
Mechanical Electrical
Gear selector lever cable adjustment (vehicles with automatic
transmission)
Starter motor
Engine (turns freely)
Battery
Fuses
Starter relay
Wiring harness(es)
Damaged, loose or corroded
connectors
Ignition switch
Generator
Transmission Control Module (TCM)
Engine Control Module (ECM)
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
Symptom Chart
Symptom Possible Causes Action The engine does
not crank (starter
motor does not
turn)
Gear selector not in P or N
position (vehicles with
automatic transmission)
Battery
Starter relay
Invalid key code received by
Central Junction Box (CJB)
Harness/Connectors

(TCM)
Engine Control Module (ECM)
Engine seized Make sure the gear selector is in the P or N position and correctly
adjusted. Check the battery condition and state of charge. Check for
DTCs indicating an immobilizer fault. Check the starter motor relay,
ignition switch and generator circuits. Refer to the electrical guides.
Check for TCM and ECM DTCs. Check that the engine turns freely. The engine does
not crank (starter
motor does turn)
