Test J: Remote Climate Control (RCC) Module Does Not Respond To NGS Tester

NOTE: After making any repair, perform data link diagnostic procedure. See DATA LINK DIAGNOSTIC TEST  under SELF-DIAGNOSTIC SYSTEM.
  1. Turn ignition switch to LOCK position. Disconnect RCC module harness connector C2044. See Figure . Inspect connector for loose, damaged or corroded terminals. If connector is okay, go to next step. If problem exists, repair connector as necessary.
  2. Disconnect in-line harness connector C243. See Figure . Inspect connector for loose, damaged or corroded terminals. If connector is okay, go to next step. If problem exists, repair connector as necessary.
  3. Measure resistance in Tan/Orange wire between terminal No. 6 at male half of in-line harness connector C243 and terminal No. 2 at DLC. See Figure and Figure . Also, measure resistance in Pink/Light Blue wire between terminal No. 2 at male half of in-line harness connector C243 and terminal No. 10 at DLC. If both resistance readings are 5 ohms or less, go to next step. If any resistance reading is greater than 5 ohms, repair open in Tan/Orange and/or Pink/Light Blue wire between male half of in-line harness connector C243 and DLC.
  4. Measure resistance in Tan/Orange wire between terminal No. 6 at female half of in-line harness connector C243 and terminal No. 3 at RCC module harness connector C2044. See Figure and Fig 1 . Also, measure resistance in Pink/Light Blue wire between terminal No. 2 at female half of in-line harness connector C243 and terminal No. 4 at RCC module harness connector C2044. If both resistance readings are 5 ohms or less, replace RCC module. If any resistance reading is greater than 5 ohms, repair open in Tan/Orange and/or Pink/Light Blue wire between female half of in-line harness connector C243 and RCC module.
