MANUAL TRANSMISSION TROUBLESHOOTING2220
The ACD mode injector lamp does not come on when the ignition
switch is ON (engine stopped)Assumed cause of concern
ACD mode indicator lamp circuit or 4WDECU malfunctions are possible.• Harness, connector malfunction
• ACD mode indicator lamp ASSY malfunction
• 4WDECU malfunction
Measurement at C106, combi. meter connector.
• Undo connector, take measurement on harness side
• Ignition switch ON
OK:battery voltage
Measurement at C37 4WDECU connector
• Undo connector, take measurement on harness side
• Ignition switch ON
• Earth 40, 51, 52 to body earth
OK:indicator lamp on
Connector check:C37
NG > repair
Fault confirmation Replace 4WDECU
Connector check:C106, C212, C210
NG > repair
Fault confirmation
Check harness between ignition switch – ACD mode
indicator lamp ASSY
• Check power supply wire to see if broken or
damaged
•NG > repair
Check ACD mode indicator lamp ASSY
NG > replace
Connector check:C37, C133, C106
NG > repair
Fault confirmation
Check harness between ACD mode indicator lamp
ASSY 4WDECU
• Check output wire to see if broken or damaged
When C37 4WDECU connector is undone, do all
ACD mode indicator lamps all go out?
Replace 4WDECU
Check connector:C37, C133, C106
NG > repair
Fault confirmation Check harness between ACD mode indicator ASSY
4WDECU
• Check output wire for earthing, shorting
NG > repair
Replace ACD mode indicator ASSY
Checking procedure 3
Checking procedure 4
Even after engine starts, at least 2 ACD mode indicator lamps
remain litAssumed cause of concern
ACD mode indicator lamp output circuit malfunction is possible.•Harness, connector malfunction
• 4WDECU malfunction
• ACD mode indicator lamp ASSY malfunction
Remarks
This phenomenon is limited to when communication with MUTII/III is possible (4WDECU power supply normal), and diagnosis
code is normal/correct.

CodeName Page Details of Change
BEngine transmission p.1-2• Due to changes in the engine control system, the
name of the wastegate solenoid valve (B-30) has
been changed to “wastegate solenoid valve 1”, and
an additional wastegate solenoid valve 2 (B-32) has
been added.
• The 4WD-ECU (C-37, 38) has been moved from
the instrument panel harness to the control harness.
• With the removal of the DVD-MMCS, the following
connectors have been removed.

• Multi-centre display (C-11, 12)

• Navigation unit (C-47)
The immobiliser ECU (C-54) has also been removed,
due to changes in the engine immobiliser system.
CInstrument panel p.1-4
• With the removal of the DVD-MMCS, the following
connectors have been removed.

• Audio unit (C-102)
