DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST A: THE MODULE DOES NOT RESPOND TO THE NGS TESTER — ANTI-LOCK BRAKE
CONTROL MODULE
A2 CHECK ANTI-LOCK BRAKE CONTROL MODULE C1942
CONNECTION
• Reconnect anti-lock brake control module C1942 and rerun DATA LINK
DIAGNOSTICS Network Test.
• Does the anti-lock brake control module respond to NGS Tester?
A3 CHECK CIRCUIT 70 (LB/W) BETWEEN IN-LINE C1946F AND
DLC C209 FOR OPEN
• With key OFF, disconnect in-line C1946F (evac/fill connector #1) from
in-line C1941M (evac/fill connector #2) and inspect C1946F and
C1941M for damage.
• With key OFF, measure the resistance of the LB/W wire between pin 7
on in-line C1946F and pin 7 on DLC C209.
• Are the connectors OK and is the resistance less than 5 ohms?
A4 CHECK CIRCUIT 70 (LB/W) BETWEEN IN-LINE C134F AND
DLC C209 FOR OPEN
• With key OFF, disconnect in-line C134 and inspect C134M and C134F
for damage.
• With key OFF, measure the resistance of the LB/W wire between pin 16
on in-line C134F and pin 7 on DLC C209.
• Are the connectors OK and is the resistance less than 5 ohms?
PINPOINT TEST B: THE MODULE DOES NOT RESPOND TO THE NGS TESTER — BATTERY CONTROL
MODULE (BCM)
B1 CHECK FUSE, POWER, AND GROUND TO TRACTION
BATTERY SUPPORT TRAY
• Check 10A fuse 12 in the electric vehicle power distribution box
(EVPDB).
• With key OFF, disconnect traction battery support tray in-line C1939 and No =
NGS Tester. Inspect C1939M, C1939F and DLC C209 for damage.
• Connect 104-Pin Breakout Box (BOB) to traction battery support tray
in-line C1939 using Traction Battery Low Voltage Service Cord.
• With key OFF, measure the voltage between BOB pins 45, 53 and
ground (BOB pin 65). (V > 10 volts)
• With key OFF, measure the resistance between BOB pins 1, 37 and
ground. (R < 5 ohms)
• Is everything OK?
B2 CHECK CIRCUITS 914 (T/O) AND 915 (PK/LB) BETWEEN
IN-LINE C1939M AND DATA LINK CONNECTOR (DLC) C209 FOR
OPEN(S)
• With key OFF, measure the resistance of the T/O wire between pin 2 on
DLC C209 and BOB pin 59.
• With key OFF, measure the resistance of the PK/LB wire between pin 10 No =
on DLC C209 and BOB pin 58.
• Are the resistances less than 5 ohms?
B3 CHECK CIRCUITS 914 (T/O) AND 915 (PK/LB) BETWEEN
IN-LINE C1939M AND IN-LINE C136M FOR OPEN(S)
