Troubleshooting

Self-diagnostic Procedures

I. When the Check Engine light has been reported on, do the following:

1. Connect the Service Check Connector terminals with a jumper wire as shown. (The 2P Service Check Connector is located under the dash on the passenger side of the car.) Turn the ignition switch on.

2. Note the CODE: the Check Engine light indicates a failure code by the length and number of blinks. The Check Engine light can indicate simultaneous component problems by blinking separate codes, one after another. Problem codes 1 through 9 are indicated by individual short blinks. Problem codes 10 through 48 are indicated by a series of long and short blinks. The number of long blinks equals the first digit, the number of short blinks equals the second digit.
