B2142-IGNITION OFF DRAW (IOD) FUSE NOT PRESENT

For a complete wiring diagram, refer to the Wiring Information.

Theory of Operation

All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is disconnected within the Totally Integrated Power Module (TIPM) when the vehicle is shipped from the factory. The IOD fuse feeds the memory and sleep mode functions for some of the electronic modules in the vehicle as well as various other accessories that require battery current when the ignition switch is in the off position.

- When Monitored:
With the Ignition on.

Odometer reading is less than 80.5 km (50 mi).

- Set Condition:
Ignition Off Draw (IOD) Fuse not installed or blown in the Totally Integrated Power Module (TIPM).





1. CHECK FOR ACTIVE DTC

NOTE: If the odometer reading is greater than 80.5 km (50 mi), DTC B219F sets instead of B2142 when the IOD fuse cannot be detected.

1. With the scan tool, record and erase DTCs.
2. Cycle the ignition switch from off to on, leaving the ignition off for a minimum of 30 seconds.
