Pinpoint Test C - Keypad Switch Does Not Illuminate

  1. Turn ignition off. Disconnect keyless entry keypad connector. Measure resistance between Pink and Black wires of keypad connector. If resistance is about 3 ohms, go to next step. If resistance is not as specified, check for open wire(s). If wire(s) are okay, replace keypad.
  2. Disconnect 16-pin control module connector. Measure resistance of Pink wire between 16-pin connector and ground. Measure resistance of Pink wire between 16-pin connector and keypad connector. If resistance is less than 5 ohms between connectors and more than 10 k/ohms between connector and ground, go to next step. If resistances are not as specified, repair Pink wire.
  3. Measure resistance of Black wire between connector and ground. If resistance is less than 5 ohms, replace control module. If resistance is more than 5 ohms, repair Black wire.
