TROUBLESHOOTING HINTS (The most
likely causes for this code to be set are:)
• ECM failed.
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: V.C.I.
• MB991827: USB Cable
• MB991910: Main Harness A
STEP 1. Using scan tool MB991958, read the diagnostic
trouble code (DTC).
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Read the DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P0602 set?
YES : Replace the ECM with one into which vehicle
information is correctly entered.
NO : It can be assumed that this malfunction is intermittent.
