Inspection Procedure 6: When "ON/OFF" Switch is Turned ON, "CRUISE" Indicator Light Inside
Combination Meter does not Illuminate (However, Cruise Control System is Normal).

CIRCUIT OPERATION

• The ECM detects "ON/OFF" switch ON signal to

illuminate the "CRUISE" indicator light within the
combination meter.

• The "CRUISE" indicator light illuminate signal is

transmitted from the ECM to the combination
meter via CAN bus line.

COMMENT

• The CAN bus line between the ECM and the

ETACS-ECU and between the ETACS-ECU and
the combination meter may be defective.

• The combination meter, ETACS-ECU or ECM

may also be defective.

TROUBLESHOOTING HINTS

• Malfunction of CAN bus system.

• Damaged harness or connector.

• Malfunction of the combination meter.

• Malfunction of the ETACS-ECU

• Malfunction of the ECM

DIAGNOSTIC PROCEDURE

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: M.U.T.-III USB Cable

• MB991910: M.U.T.-III Main Harness A

CAUTION

If there is any problem in the CAN bus lines, an incorrect
DTC may be set. Prior to this diagnosis, diagnose the CAN
bus lines (Refer to GROUP 54C, Trouble code diagnosis
