3.3.2 Intermittent Code
A diagnostic trouble code that is not there every time the engine control module/SKIM checks the
circuit is an ªintermittentº code. Most intermittent codes are caused by wiring or connector
problems. Defects that come and go like this are the most difficult to diagnose; they must be
looked for under specific conditions that cause them. The following checks may assist you in
identifying a possible intermittent problem:
²Visually inspect related wire harness connectors. Look for broken, bent, pushed out, or
corroded terminals.
²Visually inspect the related harnesses. Look for chafed, pierced, or partially broken wire.
²Refer to any hotlines or technical service bulletins that may apply.
NOTE: Electromagnetic (radio) interference can cause an intermittent system malfunction. This
interference can interrupt communication between the ignition key transponder and the SKIM.
3.3.3 Reset Counter
The reset counter counts the number of times the vehicle has been started since codes were last
set, erased, or the battery was disconnected. The reset counter will count up to 255 start counts.
The number of starts helps determine when the trouble code actually happened. This is recorded
by the ECM and can be viewed on the DRB as the RESET COUNTER.
When there are no trouble codes stored in memory, the DRB will display ªNO TROUBLE CODES
FOUNDº and the reset counter will show ªRESET COUNT = XXX.º
