Pinpoint Test Ac : The Powertrain Malfunction (Wrench) Indicator Is Never Or Always On
- Normal Operation and Fault Conditions
See Powertrain Malfunction (Wrench) Indicator. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the transmission service required, engine service required, AWD service required or body service required message is missing for less than 5 seconds, the IPC defaults the powertrain malfunction (wrench) indicator to the last indication state (on or off), based upon the last message received.
If the transmission service required, engine service required, AWD service required or body service required message is missing for 5 seconds or longer, the IPC defaults the powertrain malfunction (wrench) indicator on.

Yes No GO to AC5 - AC5 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) INDICATOR LAMP CONTROL ACTIVE COMMAND USING A DIAGNOSTIC SCAN TOOL
- Using a diagnostic scan tool, view the IPC Parameter Identifications (PIDs).
- Select the IPC powertrain malfunction (wrench) indicator (WRENCH_IND) PID.
- Command the powertrain malfunction (wrench) indicator on and off while observing the indicator.
Does the powertrain malfunction (wrench) indicator illuminate when commanded on and turn off when commanded off?
Yes If the powertrain malfunction (wrench) RTT indicator is never on, the system is operating correctly at this time. There are currently no vehicle concerns present that require the powertrain malfunction (wrench) RTT indicator display. If the powertrain malfunction (wrench) RTT indicator is always on, Refer to PCM GUIDED ROUTINE TESTING No INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) .
