Determination Procedure<\/p>\n

\n
\n
Caution<\/div>\n<\/dd>\n
\n
\n
\u2022 When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.<\/div>\n
\u2022 When inspecting the connector, touch it with a paper clip or similar thin pin without directly inserting a tester probe into the terminal.<\/div>\n<\/div>\n<\/dd>\n<\/dl>\n

\n
1<\/div>\n<\/td>\n
\n
INSPECT CAN LINE IN BODY CONTROL MODULE (BCM) FOR SHORT TO GROUND<\/div>\n
\u2022 Switch the ignition off.<\/div>\n
\u2022 Disconnect the negative battery cable. (See NEGATIVE BATTERY TERMINAL DISCONNECTION\/CONNECTION [(US)]<\/a>.)<\/div>\n
\u2022 Disconnect the connector 3 which has body control module (BCM) terminals 3U and 3W.<\/div>\n
\u2022 Inspect for continuity at the following terminals:<\/div>\n
\n
\n
\u2015 Between body control module (BCM) terminal 3U (wiring harness side) and body ground<\/div>\n
\u2015 Between body control module (BCM) terminal 3V (wiring harness side) and body ground<\/div>\n<\/dd>\n<\/dl>\n
\u2022 Is there continuity?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to the next step.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Replace the body control module (BCM) because there is a short to ground in the body control module (BCM).<\/div>\n
(See BODY CONTROL MODULE (BCM) REMOVAL\/INSTALLATION<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
2<\/div>\n<\/td>\n
\n
INSPECT CAN LINE IN TELEMATICS COMMUNICATION UNIT FOR SHORT TO GROUND<\/div>\n
\u2022 Disconnect the telematics communication unit connector.<\/div>\n
\u2022 Inspect for continuity at the following terminals:<\/div>\n
\n
\n
\u2015 Between telematics communication unit terminal 1Q (wiring harness side) and body ground<\/div>\n
\u2015 Between telematics communication unit terminal 1S (wiring harness side) and body ground<\/div>\n<\/dd>\n<\/dl>\n
\u2022 Is there continuity?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Repair or replace the wiring harness between the body control module (BCM) and telematics communication unit because the wiring harness is shorted to ground.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Replace the telematics communication unit because there is a short to ground in the telematics communication unit.<\/div>\n
