Checking the Diagnostic Trouble Code IDTCI
with the Servic€ Check Connestol and Special Tool
when the PcM senses an abnormality in the input or output systems' the E ('97 - 98) or E (gS - OO) indicator light in the
gauge assembly may blink.
When the Service Check Connector (2P) (located under the dash on the passenger side) is connected with the special tool
as shown, the E or E indicator light will blink the Diagnostic Trouble Code (DTC) when the ignition switch is turned ON
{ ).
when the E or E indicator light has been reponed on, connect the service check connector (2P) to the special tool
Then turn ON (ll) the ignition switch and observe the E or E indicator light'

codes 1 through 9 are indicated by individual short blinks. codes 1o and above are indicated by a series of long and short
blinks. one long blink equals 1o short blinks. Add the long and short blinks together to determine the code. After deter-
mining the code, refer to the electrical system symptom-to-component chart on pages 14-60 and 14-61 for the '97 model,
and pages 14-62 and 14-63 tor the '98 - 00 models.
