  1. STEP 1. Check the operation of the keyless operation system (keyless entry system). Operate the keyless operation key and check that all doors lock and unlock. Q: Is the check result normal? YES: Go to Step 2. NO: Refer to «INSPECTION PROCEDURE 15: "KEYLESS ENTRY SYSTEM DOES NOT WORK»(ref-592552-S14812083352014011000000) ."
  2. STEP 2. Using scan tool MB991958, read the diagnostic trouble code. CAUTION: To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958. Connect scan tool MB991958. Refer to " «HOW TO CONNECT SCAN TOOL (M.U.T.-III)»(ref-592552-S08493997622014011000000) ." Turn the ignition switch to the "ON" position. Check whether the KOS-ECU related DTC is set.
