Check for Diagnostic Trouble Codes (DTC's) in 1993 1998 Jeep Grand Cherokees

If the 'Check Engine' light in your 1993-1998 Jeep Grand Cherokee is on, you don't have to pay extra for a repair shop to check for Diagnostic Trouble Codes (DTC's). You are able to check for these codes yourself by just using your key!

Steps

  1. Place the ignition key into the ignition slot, and turn to ON (NOT RUN) 3-5 times.
  2. Count how many times the 'Check Engine' light flashes. Each time there is a slight pause, that is the first digit of a 2-digit code. (i.e. If the 'Check Engine' light flashes 5 times, then pauses, then flashes again 5 times, the first code is '55'). Longer pauses indicate the start of a second 2-digit code. Write these codes down.
  3. The code '55' indicates the end of sequence (this will appear if no codes are present or if the 'Check Engine' light is not on).
