Whenever the module is awake.

When the Totally Integrated Power Module (TIPM) senses a draw of between 65 and 100 amps for 80 ms., this code will set.

Note. The most probable cause for this DTC to set is that the driver held all four window switches down or up for an extended period of time thereby causing the high side driver, in the TIPM, to overheat and cut out. Once the high side driver is opened, it will remain open for approximately 10 seconds or until the next key cycle. However, the code will remain as stored.

B191D-WINDOW CONTROL CIRCUIT OVERCURRENT

Note. The schematic shows just the Left Rear Window Motor circuit. The other Passenger Window Motor circuits are similar.

For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .

Whenever the module is awake.

When the Totally Integrated Power Module (TIPM) senses a draw of over 35 amps for over 120 ms. on the F981 Ignition Switch Output circuit, this code will set

Note. A possible cause for this DTC to set would be if the driver held more than one window switch down for an extended period of time thereby causing the high side driver, in the TIPM, to overheat and cut out. Once the high side driver is opened, it will remain open until the next key cycle. However, the code will remain as stored.
