Test 13: CAN L Data Line Short To Ground (SLK230)

Turn ignition switch to LOCK position. Disconnect PSE control module from breakout box leaving breakout box connected to PSE control module harness connector. Disconnect combination control module harness connector. Measure resistance between terminals No. 3 and 9 at breakout box. If resistance is greater than 20 k/ohms, CAN L data line is okay at this time. If resistance is 20 k/ohms or less, repair short to ground in CAN L data line. See WIRING DIAGRAMS .
