Pinpoint Test AF: The Powertrain Malfunction (Wrench) Warning Indicator Is Never/Always On (Fusion Non-Hybrid)
Normal Operation
The Instrument Panel Cluster (IPC) receives the powertrain malfunction data from the PCM for the Electronic Throttle Control (ETC) status, from the Transmission Control Module (TCM) for the transaxle status and from the 4X4 control module for the All-Wheel Drive (AWD) status over the High Speed Controller Area Network (HS-CAN) communication bus.
When a fault condition exists in the ETC (Electronic Throttle Control) system, the PCM provides the IPC (Instrument Panel Cluster) with a message to turn the powertrain malfunction (wrench) warning indicator on. When a fault condition exists in the transaxle, the TCM (Transmission Control Module) provides the IPC (Instrument Panel Cluster) with a message to turn on the powertrain malfunction (wrench) indicator. When an AWD (All-Wheel Drive) fault condition exists, the 4X4 control module sends the IPC (Instrument Panel Cluster) a message to turn the powertrain malfunction (wrench) warning indicator on.
If the ETC (Electronic Throttle Control) status message is missing for less than 5 seconds, the powertrain malfunction (wrench) indicator remains in the last indication mode (on or off). If the ETC (Electronic Throttle Control) message is missing for greater than 5 seconds, the IPC (Instrument Panel Cluster) sets DTC U0100:00 and defaults the powertrain malfunction (wrench) warning indicator on.
If the transaxle status message is missing for less than 5 seconds, the powertrain malfunction (wrench) indicator remains in the last indication mode (on or off). If the transaxle message is missing for greater than 5 seconds, the IPC (Instrument Panel Cluster) sets DTC U0101:00 and defaults the powertrain malfunction (wrench) warning indicator on.
If the AWD (All-Wheel Drive) status message is missing for less than 5 seconds, the powertrain malfunction (wrench) indicator remains in the last indication mode (on or off). If the AWD (All-Wheel Drive) status message is missing for greater than 5 seconds, the IPC (Instrument Panel Cluster) sets DTC U0102:00 and defaults the powertrain malfunction (wrench) warning indicator on.
This pinpoint test is intended to diagnose the following:
- ETC (Electronic Throttle Control) concern
- AWD (All-Wheel Drive) concern
- Transaxle concern
- IPC (Instrument Panel Cluster)
PINPOINT TEST AF : THE POWERTRAIN MALFUNCTION (WRENCH) WARNING INDICATOR IS NEVER/ALWAYS ON (FUSION NON-HYBRID)
AF1 CARRY OUT THE IPC (Instrument Panel Cluster) INDICATOR LAMP CONTROL ACTIVE COMMAND USING THE SCAN TOOL
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IPC (Instrument Panel Cluster) DataLogger.
- Select the IPC (Instrument Panel Cluster) powertrain malfunction (wrench) warning indicator (TRANSA_LMP) active command. Command the powertrain malfunction (wrench) warning indicator on and off while observing the powertrain malfunction (wrench) warning indicator.
Does the powertrain malfunction (wrench) warning indicator illuminate when commanded on, and turn off when commanded off?
Yes
GO to AF2.
No
INSTALL a new IPC (Instrument Panel Cluster). REFER to Instrument Panel Cluster (IPC) . TEST the system for normal operation.
AF2 RETRIEVE THE RECORDED DTCs FROM THE IPC (Instrument Panel Cluster) SELF-TEST
- Check for recorded DTCs from the IPC (Instrument Panel Cluster) self-test.
Are any DTCs recorded?
Yes
For DTC U0100:00, GO to Pinpoint Test BF. Pinpoint Test BF: DTC U0100:00
For DTC U0101:00, GO to Pinpoint Test BG. Pinpoint Test BG: DTC U0101:00
For DTC U0102:00, GO to Pinpoint Test BH. Pinpoint Test BH: DTC U0102:00
For all other DTCs, REFER to DTC Charts. Instrumentation, Message Center and Warning Chimes
No
GO to AF3.
AF3 RETRIEVE THE RECORDED DTCs FROM THE PCM KOEO (Key ON Engine OFF) SELF-TEST
- Check for recorded PCM DTCs from the Key ON Engine OFF (KOEO) self-test.
Are any DTCs recorded?
Yes
DIAGNOSE all PCM DTCs. REFER to Computers and Control Systems Information.
No
GO to AF4.
AF4 RETRIEVE THE RECORDED DTCs FROM THE TCM (Transmission Control Module) SELF-TEST
- Check for recorded TCM (Transmission Control Module) DTCs from the self-test.
Are any DTCs recorded?
Yes
DIAGNOSE all TCM (Transmission Control Module) DTCs. REFER to Computers and Control Systems Information.
No
DIAGNOSE all 4X4 control module DTCs. REFER to Transfer Case.
