Retrieving Trouble Codes
- Ensure battery voltage is greater than 11 volts and throttle valve is fully closed. Place transmission or transaxle in Neutral and turn off all accessory switches.
- To enter diagnostic mode, turn ignition on. DO NOT start engine. Install jumper wire between terminals of engine check connector. See Fig 1.
- Count number of flashes from "CHECK ENGINE" light. If system is operating properly (with no codes), "CHECK ENGINE" light will blink continuously and evenly.
- On all models, a code will be identified by a .5 second flash on and off for the first number. A 1.5 second pause will occur followed by the second number. See Figure.
- If more than one code is stored, a 2.5 second pause will occur prior to the flashing of the second code. Once all codes have been displayed, a 4.5 second pause will occur and code(s) will repeat.
- On all models, trouble codes are given from smallest value in order to largest value. After code(s) are retrieved, remove jumper wire to exit diagnostic mode.
- Compare trouble code to that listed to locate probable cause. See appropriate TROUBLE CODE IDENTIFICATION and TROUBLE CODES & PROBABLE CAUSE tables.
CAUTION:
Ensure trouble codes are cleared after performing repair. Road test and recheck that trouble code does not exist.
