DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST A: DTC C1862 CONTACTOR CIRCUIT FAILURE
A6 CHECK CIRCUIT 3136 (W) FOR OPEN
• With key OFF, disconnect contactor box C1982 and measure the
resistance of the W wire between pin 3 on contactor box C1982 and
BOB pin B7.
• Is the resistance less than 5 ohms?
Emergency Power Off (EPO)/Interlock
System
Diagnostic Trouble Code (DTC) Definition
The following DTC relates to the Emergency Power
Off (EPO)/Interlock System:
• DTC B2517 Emergency Power Off System
Faulted
— An emergency power off (EPO) occurs when
the contactor box outputs an EPO signal
through the EPO circuit to the battery control
module (BCM), interface adapter assembly
(IAA) module and positive temperature
coefficient (PTC) switching module. If an
EPO condition occurs, the contactor box
disables the high-voltage system and the IAA
module sets DTC B2517. An open
high-voltage connector interlock, an EPO
request from the BCM and an activated inertia
switch will cause an EPO condition. The IAA
module will not set DTC B2517 if the inertia
switch is activated. If the inertia switch is
activated, the power reset indicator will
illuminate.
