STEP 9. Check for harness damage between accelerator 
pedal position sensor connector C-24 (terminal No. 3) and 
ENGINE-ECU connector B-21 (terminal No. 59).
Q: Is the harness wire in good condition?

YES : Go to Step 10.
NO :  Repair it. Then go to Step 12.

STEP 11. Replace the accelerator pedal position sensor.
(1) Replace the assertory pedal position sensor.
(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 P2138 set?

YES : Then go to Step 12.
NO :  The inspection is complete.

STEP 12. Using diagnostic tool , read the diagnostic 
trouble code (DTC).

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) After the DTC has been deleted, read the DTC again.
(4) Turn the ignition switch to the "LOCK"(OFF) position.

Q: Is DTC P2138 set?

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

DTC U1100: ENGINE CAN TIME-OUT/Not equipped

CAUTION

• If the ENGINE-ECU outputs DTC U1102, make 

sure to diagnose the CAN bus line.

• Before replacing the ENGINE-ECU, make sure 

that the communication circuit is operating 
normally.

.

DTC SET CONDITIONS

Check Conditions

• Battery positive voltage is 10 volts or higher.

Judgement Criteria

• Unable to receive combination meter signals 

through the CAN bus line.

• No MIL.

.

COMMENT

Current Trouble

• Some of the possible causes are a harness or 

connector damage between the ENGINE-ECU 
and the combination meter on the CAN bus line, 
a failure in the combination meter power supply 
system, a failure in the combination meter, or a 
failure in the ENGINE-ECU.

Past Trouble

• Proceed to troubleshoot based on a harness or 

connector damage on the CAN bus line between 
the ENGINE-ECU and combination meter, and a 
failure in the combination meter power supply 
system. Refer to "How to cope with past trouble" 
(Refer to GROUP 00, How to Use Troubleshoot-
ing/Inspection Service Points 

− How to Cope with 

Intermittent Malfunctions 

P.00-14

).

NOTE: If a malfunction occurred in the past, a failure 
cannot be discovered through the MUT 

 III CAN bus 

diagnosis even if there might be a problem with the 
CAN bus. In this case, refer to GROUP 00, How to 
Use Troubleshooting/Inspection Service Points 

 

How to Cope with Intermittent Malfunctions 

P.00-14

Furthermore, it is possible to narrow down the areas 
of the possible failures from the DTCs that are output 
by the ECUs, which are communicating on the CAN 
bus (Refer to GROUP 54C, CAN bus line Diagnos-
tics Flow 

P.54C-6

).

.

EOBD DRIVE CYCLE PATTERN

None.

.

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

• CAN line harness damage or connector damage.

• Combination meter failed.
• ENGINE-ECU failed.

• Refer to component locations GROUP-

70

• Refer to configuration diagrams GROUP-

80

• Refer to circuit diagrams GROUP-

90

DIAGNOSIS

Required Special Tools:

• : Diagnostic tool (MUT-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: USB Cable

• MB991910: Main Harness A
