Test F: Central Timer Module (CTM) Does Not Respond To NGS Tester

  1. Turn ignition switch to LOCK position. Remove and inspect fuse No. 1 (80-amp) from power distribution box. If fuse is okay, install fuse and go to next step. If fuse is blown, replace fuse. If fuse blows again, check for short to ground.
  2. Disconnect CTM from back of central junction box. Measure voltage at terminal No. 18 at CTM connector C23 (fuse box side). See Figure . If battery voltage exists, go to next step. If battery voltage does not exist, replace central junction box.
  3. Measure resistance between ground and terminal No. 16 at CTM connector C23. If resistance is 5 ohms or less, replace CTM. If resistance is greater than 5 ohms, replace central junction box.
