90

DIAGNOSIS

Required Special Tools:

• : Diagnostic tool (MUT-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: USB Cable

• MB991910: Main Harness A

STEP 1. Using diagnostic tool , check data list item 1: 
Power supply voltage.

CAUTION

To prevent damage to diagnostic tool , always turn the 
ignition switch to the "LOCK"(OFF) position before con-
necting or disconnecting diagnostic tool .
(1) Connect diagnostic tool to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Set diagnostic tool to the data reading mode for item 1, 

Power supply voltage.

• Check that it is between 9.99 and 17.05 volts.

(4) Turn the ignition switch to the "LOCK"(OFF) position.

Q: Is the measured voltage within specification?

YES : Go to Step 2.
NO :  Refer to GROUP 16 , Engine Electrical - Charging 

System 

P.16-3

. Then go to Step 2.

STEP 2. Using diagnostic tool , read the diagnostic trouble 
code (DTC)
(1) Turn the ignition switch to the "ON" position.
(2) Check the diagnostic trouble code (DTC).

Q: Is DTC P0562 set?

YES : Retry the troubleshooting.
NO :  The inspection is complete.

DTC P0603: EEPROM Malfunction

CAUTION

The MIL may or may not illuminate when DTC 
P0603 is detected. Refer below:

.

TECHNICAL DESCRIPTION

• ENGINE-ECU performs a check on the match 

between hardware and software for different 
transmission configurations (M/T, A/T).

.

Check Conditions

• Ignition switch is in "ON" position.

Judgement Criteria

• Mismatch between software variant and trans-

misssion.

• EPPROM defect - No MIL.

• Incorrect ECU fitted - MIL activated immediately 

and engine only idling.

.

EOBD DRIVE CYCLE PATTERN

None.

.

TROUBLESHOOTING HINTS (The most 
likely causes for this code to be set are:)

• EPPROM defect in ENGINE-ECU.

• Incorrect ENGINE-ECU fitted.

• Refer to component locations GROUP-

70

• Refer to configuration diagrams GROUP-

80

• Refer to circuit diagrams GROUP-

ignition switch to the "LOCK"(OFF) position before con-
necting or disconnecting diagnostic tool .
(1) Connect diagnostic tool to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) After the DTC has been deleted, read the DTC again.
(4) Turn the ignition switch to the "LOCK"(OFF) position.

Q: Is DTC P0603 set?

YES : Replace the ENGINE-ECU. 
NO :  It can be assumed that this malfunction is intermittent. 

Refer to GROUP 00, How to Use
