Diagnostic Circuit Check
- Ensure battery voltage is at least 11 volts, throttle valve is fully closed and all accessories are off. Turn ignition on. The CHECK ENGINE light should come on. If CHECK ENGINE light does not come on, check bulb, fuse and circuitry between ECU and ignition switch. See ECU LOCATION table. Start engine, light should go off. If light stays on, hard fault is stored or a circuitry fault exists.CAUTION: Ensure no other terminals are contacted while installing jumper wire between "T" terminal and ground terminal.
- Install Sub-Harness (SST 09991-87702-000) on 6-pin check connector located near top of transaxle (near battery on Rocky). Install a jumper wire between "T" terminal and ground terminal. See Fig 1 . Turn ignition on but do not start engine.
- Read trouble code by observing flashing number sequence of CHECK ENGINE light. If system is normal, a code No. 1 is stored by ECU. The CHECK ENGINE light will flash for .48 second, 4.5 seconds after ignition is turned on. See Fig 2 .
- The system will pause for 4.5 seconds, then flash for .48 second again. This pattern will be repeated. If one trouble code is stored, the CHECK ENGINE light will come on .48 second for the same number of times as the trouble code. For example, if the CHECK ENGINE light flashes twice, then a Code 2 has been set.
- After 4.5 seconds, the trouble code will be repeated. If multiple trouble codes exist, the CHECK ENGINE light will display one trouble code then delay for 2.5 seconds and display another trouble code.
- ECU will flash smaller number trouble code first and proceed to larger number trouble code. If trouble codes are present, go to TROUBLE CODE CHARTS to identify the circuit or component requiring inspection.
