Pinpoint Test AL: The Stop Safely Hazard Message Center Warning Indicator Is Never/Always On (Hybrid)
Normal Operation
The stop safely hazard message center warning indicator informs the driver that a transaxle fault condition exists or a powertrain shutdown is about to occur and service on the vehicle is required. The PCM, the Transmission Control Module (TCM) and the Battery Pack Sensor Module (BPSM) provide the Instrument Panel Cluster (IPC) the stop safely hazard message center indicator request over the High Speed Controller Area Network (HS-CAN) communication bus.
If the stop safely hazard message center indicator request is missing or invalid for less than 5 seconds from any of the source modules (PCM, TCM or BPSM), the stop safely hazard message center warning indicator remains in the last indication mode (on or off) based upon the last known good message received.
If the stop safely hazard message center indicator request is missing for more than 5 seconds from the PCM, the IPC sets DTC U0100:00 in continuous memory and defaults the stop safely hazard message center warning indicator on.
If the stop safely hazard message center indicator request is missing for more than 5 seconds from the TCM, the IPC sets DTC U0101:00 in continuous memory and defaults the stop safely hazard message center warning indicator on.
If the stop safely hazard message center indicator request is missing for more than 5 seconds from the BPSM, the IPC sets DTC U0111:00 in continuous memory and defaults the stop safely hazard message center warning indicator on.
This pinpoint test is intended to diagnose the following:
- Powertrain concern
- Traction battery concern
- Transaxle concern
- IPC
PINPOINT TEST AL: THE STOP SAFELY HAZARD MESSAGE CENTER WARNING INDICATOR IS NEVER/ALWAYS ON (HYBRID ONLY)
-------------------------------------------------
AL1 CHECK THE MESSAGE CENTER OPERATION
- Close all doors and the luggage compartment lid.
- Ignition ON.
- Open the driver door while monitoring the message center displays.
- Does the message center display the door ajar message center warning indicator along with the DRIVER DOOR AJAR text?
Yes
GO to AL2.
No
INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) Instrument Panel Cluster (IPC). TEST the system for normal operation.
-------------------------------------------------
AL2 RETRIEVE THE RECORDED DTCs FROM THE PCM KOEO SELF-TEST
- Check for recorded PCM DTCs from the Key ON Engine OFF (KOEO) self-test.
- Are any PCM DTCs recorded?
Yes
REFER to Computers and Control Systems Information.
No
GO to AL3.
-------------------------------------------------
AL3 RETRIEVE THE RECORDED DTCs FROM THE TCM SELF-TESTS
- Check for recorded TCM DTCs from the continuous and on-demand self-tests.
- Are any TCM DTCs recorded?
Yes
REFER to Computers and Control Systems Information.
No
GO to AL4.
-------------------------------------------------
AL4 RETRIEVE THE RECORDED DTCs FROM THE BPSM SELF-TEST
- Check for recorded BPSM DTCs from the continuous and on-demand self-tests.
- Are any BPSM DTCs recorded?
Yes
REFER to Multifunction Electronic Modules Testing and Inspection.
No
GO to AL5.
-------------------------------------------------
AL5 RETRIEVE THE RECORDED DTCs FROM THE IPC SELF-TEST
- Check for recorded IPC DTCs from the self-test.
- Are any DTCs recorded?
Yes
REFER to DTC Charts. Instrumentation, Message Center and Warning Chimes
No
INSTALL a new IPC. REFER to Instrument Panel Cluster (IPC) Instrument Panel Cluster (IPC). TEST the system for normal operation.
