Normal Operation and Fault Conditions
Refer to: Starting System - System Operation and Component Description ).
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0850 | Park/Neutral Switch Input Circuit | This DTC sets when the PCM detects a mismatch between the hardwired park/neutral circuit and the message broadcast over the High Speed Controller Area Network (HS-CAN). |
| P0851 | Park/Neutral Switch Input Circuit Low | This DTC sets when the PCM detects a short to ground on the park/neutral circuit. |
| P0833:23 | Clutch Pedal Switch B Circuit: Signal Stuck Low | This DTC sets when the BCM detects a short to ground on the clutch bottom of travel circuit during an on-demand self test. |

DTC FAULT TRIGGER CONDITIONS
Correct starter operation relies on correct mounting of the starter to the engine, alignment of the starter ring gear to the flexplate and correct functioning of the starter assembly (internal gears, bearings).
Without push button start
REFER to: Starting System - without Push Button Start .
With push button start
REFER to: Starting System - with Push Button Start .
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0615 | Starter Relay Circuit | This DTC is set when the PCM detects a fault in the starter relay control circuit(s). |
DTC FAULT TRIGGER CONDITIONS
When the ignition is in the ON or START mode, the BCM supplies ground for the coil (control) side of the ignition relay. The energized ignition relay supplies battery voltage to the BJB, the PCM and multiple components through the ignition relay output circuit. The BCM sends ignition mode information via the High Speed Controller Area Network (HS-CAN).
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P2531 | Ignition Switch Run Position Circuit Low | This DTC is set when the PCM detects no voltage on the ignition relay output circuit when the BCM indicates ignition is in the ON or START mode. |
| P2532 | Ignition Switch Run Position Circuit High | This DTC is set when the PCM detects voltage on the ignition relay output circuit when the BCM indicates ignition is in the OFF mode. |
DTC FAULT TRIGGER CONDITIONS
When the ignition is turned to the START position or the ignition switch - push button start has been pressed, the PCM receives a voltage signal on the crank detect circuit. When the required inputs have been received, the PCM supplies voltage and ground to the starter relay coil.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P2534 | Ignition Switch Run/Start Position Circuit Low | This DTC is set when the PCM detects a short to ground on the crank detect circuit. The fault condition is observed as no power in any ignition mode due to BCM fuse 78 (5A) opening after the ignition switch - push button start is pressed (with push button start) or the ignition switch is placed in the START position (without push button start). |
| P2535 | Ignition Switch Run/Start Position Circuit High | This DTC is set when the PCM detects a short to voltage on the crank detect circuit while engine is running. |
DTC FAULT TRIGGER CONDITIONS
The wake-up control circuit wakes up the PCM prior to engine cranking. The PCM needs to wake up prior to a crank request so it has time to go through its initialization. The wake-up control circuit is controlled by the BCM. The BCM activates the wake-up control circuit when: the driver door is opened. a key is inserted into the ignition. or when the ignition is in the ON or START position.
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| B10E5:11 | PCM Wake-up Signal: Circuit Short to Ground | Set by the BCM when a short to ground is detected on the wake-up control circuit. |
| B10E5:15 | PCM Wake-up Signal: Circuit Short to Battery or Open | Set by the BCM when a short to voltage or an open is detected on the wake-up control circuit. |
