self-test for the IAA module and BCM.
•
Do IAA module DTCs C1862 Contactor Circuit Failure and U2015
No = GO to A2.
Signal Link Fault (Non SCP), TIM DTC B1676 Battery Pack Voltage
Out of Range, and BCM DTC C1837 Battery Heater Circuit Failure
all occur?
If other BCM DTCs occur,
REFER to the BCM DTC
Index in Section 100-07.
A2 CHECK HIGH-VOLTAGE AUXILIARY BUS STATUS
•
With key ON, monitor IAA module PID AUXHVB. Yes = GO to A3.
•
Does the AUXHVB PID indicate AVAILA?
No = If AUXHVB PID indicates
UNAVAI, RETRIEVE
DTCs from the battery
control module (BCM).
REFER to Section 100-07.
If AUXHVB PID indicates
EPO or INERSW, REFER
to Emergency Power Off
(EPO)/Interlock System in
this section.
A3 CHECK AUXILIARY CONTACTOR RELAY STATUS
•
With key ON, monitor IAA module PID AUX HVC. Yes = System OK. CHECK wiring
for intermittent connections.
•
Does the AUX HVC PID indicate CLOSED?
No = If AUX HVC PID
indicates OPEN, GO to A4.
If AUX HVC PID
indicates OFAULT, GO to
A6.
A4 CHECK CHARGER CORD STATUS
NOTE: Verify the power control station (PCS) charger cord is not plugged
Yes = GO to A5.
into the charger inlet before performing this test step.
•
With key OFF, monitor BCM PID CHGCORD.
•
Does the CHGCORD PID indicate OUT?
No = RETRIEVE DTCs from the
BCM. REFER to Section
100-07.
A5 VERIFY AVAILABILITY OF AUXILIARY HIGH-VOLTAGE BUS
•
With key ON, monitor IAA module PID AUXHVB. Yes = REPLACE the IAA module.
REFER to Section 412-04.
•
Does the AUXHVB PID indicate AVAILA?
No = RETRIEVE DTCs from the
BCM. REFER to Section
100-07.
