DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST D: THE MODULE DOES NOT RESPOND TO THE NGS TESTER — TRACTION INVERTER
MODULE (TIM)
• With key OFF, disconnect TIM C4998, C4999 and NGS Tester. Inspect
TIM C4998, C4999 and DLC C209 for damage.
• Connect 104-Pin Breakout Box (BOB) to TIM C4998, C4999 using the
BCM/TIM BOB Adapter Cable & Overlay; leave the TIM disconnected.
• With key ON, measure the voltage between BOB pins A9, A10, A19,
A20 and ground (BOB pin A29). (V > 10 volts)
• With key OFF, measure the resistance between BOB pins A29, A39 and
ground. (R < 5 ohms)
• Are the values correct?
D2 CHECK CIRCUITS 914 (T/O) AND 915 (PK/LB) BETWEEN DATA
LINK CONNECTOR (DLC) C209 AND TRACTION INVERTER
MODULE (TIM) C4998 FOR OPEN(S)
• With key OFF, measure the resistance of the T/O wire between pin 2 on
DLC C209 and BOB pin A5.
• With key OFF, measure the resistance of the PK/LB wire between pin 10 No =
on DLC C209 and BOB pin A15.
• Are the connectors OK and are the resistances less than 5 ohms?
D3 CHECK TIM C4998, C4999 CONNECTION
• Remove the BOB, reconnect TIM C4998, C4999 and rerun DATA LINK
DIAGNOSTICS Network Test.
• Does the TIM respond to NGS Tester?
D4 CHECK CIRCUITS 914 (T/O) AND 915 (PK/LB) BETWEEN
IN-LINE C3999F AND DLC C209 FOR OPEN(S)
• With key OFF, disconnect in-line C3999 and inspect C3999M and
C3999F for damage.
• With key OFF, measure the resistance of the T/O wire between pin 11
on in-line C3999F and pin 2 on DLC C209.
• With key OFF, measure the resistance of the PK/LB wire between pin 9
on in-line C3999F and pin 10 on DLC C209.
• Are the connectors OK and are the resistances less than 5 ohms?
D5 CHECK CIRCUITS 914 (T/O) AND 915 (PK/LB) BETWEEN
IN-LINE C201F AND DLC C209 FOR OPEN(S)
• With key OFF, disconnect in-line C201 and inspect C201M and C201F
for damage.
• With key OFF, measure the resistance of the T/O wire between pin 71
on in-line C201F and pin 2 on DLC C209.
• With key OFF, measure the resistance of the PK/LB wire between pin 11 No =
on in-line C201F and pin 10 on DLC C209.
• Are the connectors OK and is the resistance less than 5 ohms?
