I just bought this SUV, used of course. I tried to put the truck in 4 wheel drive and two things happen( I have 2L, 4L, 4H and 4 wheel assist). I hear a clicking sound coming from the dash board and the lights on the selected buttons flash. Can you please give me some info on trouble shooting this problem or maybe a salution. Thank you.

RETRIEVING CODES 1. Turn ignition off for at least 6 seconds. Locate DLC near right side of steering column. Install jumper wire between diagnostic pigtail (Orange wire at DLC, terminal No. 13) and ground. 2. Turn ignition on (engine off). Observe shift select buttons. If all shift select buttons blink once at same time then stop, no DTCs are stored. If only one code is stored, that code will blink repeatedly, with a 3 second delay between sequences. If more than one code is present, next code will flash after a 3 second delay, then sequence will repeat. Count number of blinks for each code. See Fig. 3 . 3. Write down all DTCs. After RETRIEVING CODES clear TCCM memory and repeat procedure. See CLEARING CODES . If DTCs return, perform appropriate DTC test. See DIAGNOSTIC TESTS . Fig. 3: Reading Diagnostic Trouble Codes (DTC) Courtesy of GENERAL MOTORS CORP. CAUTION: Check system operation prior to retrieving codes. See FUNCTION TEST . NOTE: Diagnostic Trouble Codes (DTC) are displayed on 3 transfer case shift select buttons. When proper conditions are met, select buttons will blink to indicate DTC from "1" to "4".
