F: PASS KEY DECODER MODULE PROGRAMMING TEST

1. Check that connector C228 is connected clean and tight. With Ignition Switch in OFF, disconnect connector C228. Turn the Ignition Switch to RUN and measure the voltage between terminal A (WHT/BLK) and a known good ground.

^ If approximately 5 volts is measured, go to step 2.

^ If 5 volts is not measured, check the WHT/BLK (1O73) wire for an open or short to ground. If OK, replace the PASS Key Decoder Module.

2. Measure the voltage between connector C228 terminals B and A.

^ If approximately 5 volts is measured, go to Test A. A: Lock Cylinder and Harness Test

^ If approximately 5 volts is not measured, check the PPL/WHT (1074) wire for an open. If OK, replace the PASS Key Decoder Module.
