Diagnostic Aids

  1. The following conditions may cause an intermittent: Intermittent short to ground in circuit No. 1073, intermittent short between circuits No. 1073 and 1074; or PASS-Key(R) resistor is shorted.
  2. If key resistor pellet is incorrect, there will be no BCM outputs to theft deterrent relay or PCM for about 3 minutes. If a key (even a proper PASS-Key(R)) is inserted or ignition is turned on again, 3-minute timeout period will reset. If battery is disconnected, timeout period will be reset when battery is reconnected.
  3. If there is a short between circuit No. 1073 (White/Black wire) and No. 1074 (Purple/White wire) between BCM and ignition switch, a no-crank condition will exist.
