ENGINE AND EMISSION CONTROL -Auto-cruise Control System17-23
Inspection Procedure 7
Hunting (repeated acceleration and deceleration) occurs
at the set vehicle speed.
Probable cause
The cause is probably a malfunction of vehicle speed sensor or GE actuator (electronic
governor).
In either case, a diagnosis code regarding the diesel fuel system must be confirmed.DMalfunction of the vehicle speed sensor

MUT-II Self-Diag code
Is a diagnosis code regarding the diesel fuel system output?YES
NO
Check trouble symptoms.NGReplace the engine-ECU.
Follow the troubleshooting regarding the diesel fuel system. (Refer
to GROUP 13C.)
Inspection Procedure 8
When the MAIN switch of the auto-cruise control switch is
turned on, the auto-cruise control indicator lamp does not
illuminate. (However, the auto-cruise control in normal.)

WARNING REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to driver and passenger (from rendering
the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
NOTE
The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring, and interconnecting
wiring. Other SRS-related components (that mayhave to be removed/installed in connectionwith SRS service or maintenance) are
indicated in the table of contents by an asterisk(*).

Code No. 22 Input shaft speed sensor systemProbable cause
If no output pulse from the input shaft speed sensor is detected for 1 second or
more while the vehicle is driving at 30 km/h or more in 4th, it isjudged that
there is a short-circuit oropencircuit in the input shaft speed sensor, and code
No. 22 is output.
If code No. 22 is output 4 times, the transmission is locked at 3rd gear (D) or
