Does the telescopic motor move the steering column when the fused jumper wire is connected to ground?

Yes

GO to D7

No	INSTALL a new power adjustable steering column telescopic motor. REFER to: Steering Column Telescopic Motor .

D7 CHECK FOR CORRECT BCMB (BODY CONTROL MODULE B) OPERATION

Disconnect and inspect all BCMB electrical connectors.

Repair:
- corrosion (install new connector or terminal - clean module pins)
- damaged or bent pins - install new terminals or pins
- pushed-out pins - install new pins as necessary

Connect the BCMB electrical connectors.

Operate the system and determine if the concern is still present.

Is the concern is still present?

Yes	CHECK OASIS for any applicable service articles: TSB, GSB, SSM, or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new BCMB. REFER to: Body Control Module B (BCMB) .

No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
