Note On Intermittents

Following conditions will result in intermittent BCM Code F32 and/or PCM Code E47:

• Momentary open or short in circuit No. 526 resulting in both Code F32 and E47.
• Momentary open or short in circuit No. 491 resulting in Code E47 only.
• Momentary loss of ignition (circuit No. 50), battery (circuit No. 840) or ground (circuit No. 751) to BCM resulting in Code E47 and intermittent display panel operation.
• Momentary loss of ignition (circuit No. 439) to PCM resulting in Code F32 and intermittent engine operation.
• Momentary loss of battery (circuit No. 480) or ground (circuit No. 450) to PCM resulting in Codes F32, E52 and intermittent engine operation.
• Momentary BCM PROM problem resulting in Codes E47, F51 and intermittent display of "-151" on ECC panel.
