Table 5-2. Flash Code Listing
The Power Module's Line Contactor Drive Circuitry failed
to de-energize during power-up self-tests.
The Power Module is reporting a "Contactor Driver 1 Per-
manently On" Fault Code (23d). Refer to CANbus docu-
mentation for Power Module Message – Status.
Drive, Steer, & Lift Up Prevented.
Help messages with the 3-3 flash code indicate an output driver problem.

Current flow to the brake solenoid was not detected during
normal brake operation.
Brake INPUT driven High (normal operation) AND Brake
STAT detected Low.
Drive & Steer Prevented
