STEP 1. Using scan tool (M.U.T.-IIISE), read the diagnostic trouble code (DTC).
caution | To prevent damage to scan tool (M.U.T.-IIISE), always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool (M.U.T.-IIISE). |
(1) Connect scan tool (M.U.T.-IIISE). Refer to HOW TO CONNECT THE SCAN TOOL (M.U.T.-IIISE) . (2) Turn the ignition switch to the "ON" position.
(3) Read the DFI and MFI-DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is the diagnostic trouble code other than P219A set?
Refer to Diagnostic Trouble Code Chart . Go to Step 2.
STEP 2. Visual check of ignition spark.
