Awasome 1999 Jeep Grand Cherokee Laredo Check Engine Light References. My 1999 cherokee sport's check engine light came on today. Web the video above shows how to locate the on board diagnostics obd plug location on your 1999 grand cherokee, how to read the trouble codes and how to reset or clear the check engine light using a scanner on your grand cherokee.
Is it ok to drive with a check. The first thing i did was go to autozone and have them check for any error codes with the obdii. The data link connector (dlc) allows you to connect the obd scanner to your jeep's ecu.
