Normal Operations
The starting system sequence of operation is as follows:
- The ignition switch is turned to the START position.
- The starter relay is activated.
- Voltage is then provided to the starter solenoid.
- The starter solenoid engages the drive pinion to the ring gear.
- The starter solenoid switches the battery current to the starter motor.
- The system remains engaged until the ignition switch is released.
Possible Causes
- Battery
- Starter motor
- Solenoid
- Fuse 11 (30 A)

- Transmission range (TR) sensor (4.0L SOHC only)
- A short to ground in the positive battery cable
- An open in the positive battery cable
- An open circuit at the S-terminal
- An open circuit at the B-terminal
- An open in the battery ground cable
- An open circuit in the starter relay input signal circuit CDC35 (BU/WH)
- An open circuit in the battery supply to starter relay input signal circuit SBB11 (BU/RD)
- An open circuit in the starter relay to the S-connector circuit CDC25 (BN/GN)
- An open circuit in the starter relay to powertrain control module (PCM) circuit CDC12 (YE)
- A short to ground in circuit CDC25 (BN/GN) or circuit CDC35 (BU/WH)
