STEP 3. Measure the ignition switch-IG signal voltage at
ECM harness side connector B-11.
(1) Disconnect the connector B-11 and measure at the harness

side.

(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 92 and ground.

• Voltage should be battery positive voltage.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts)

present?
YES : Go to Step 5.
NO : Go to Step 4.

STEP 4. Check harness connector C-304 at ETACS-ECU for
damage.
Q: Is the harness connector in good condition?

YES : Repair harness wire between ETACS-ECU connector

C-304 (terminal No. 10) and ECM connector B-11
(terminal No. 92) because of open circuit or short
circuit to ground. Then go to Step 11.

NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 11.

STEP 5. Check harness connector C-304 at ETACS-ECU for
damage.
Q: Is the harness connector in good condition?

YES : Go to Step 6.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 11.

STEP 6. Check for harness damage between ETACS-ECU
connector C-304 (terminal No. 10) and ECM connector B-11
(terminal No. 92).
Q: Is the harness wire in good condition?

YES : Go to Step 7.
NO : Repair it. Then go to Step 11.

STEP 7. Check harness connector A-33X at MFI relay for
damage.
Q: Is the harness connector in good condition?

YES : Go to Step 8.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 11.

STEP 8. Check the MFI relay.
(1) Remove the MFI relay.
(2) Check for continuity between the MFI relay terminals No. 1

and No. 3.

• There should be continuity.

(3) Use jumper wires to connect MFI relay terminal No. 3 to the

positive battery terminal and terminal No. 1 to the negative
battery terminal.

(4) Check for continuity between the MFI relay terminals No. 4

and No. 2 while connecting and disconnecting the jumper
wire at the negative battery terminal.

• Continuity (2 ohms or less) <Negative battery terminal

connected>

• Should be open loop <Negative battery terminal discon-

nected>

(5) Install the MFI relay.
Q: Is the measured resistance within the specified range?

YES : Go to Step 9.
NO : Replace the MFI relay. Then go to Step 11.

STEP 9. Check for short circuit to ground between MFI
relay connector A-33X (terminal No. 1) and ECM connector
B-11 (terminal No. 73).
Q: Is the harness wire in good condition?

YES : Go to Step 10.
NO : Repair it. Then go to Step 11.

STEP 10. Using scan tool MB991958, read the diagnostic
trouble code (DTC).

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 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 P0606 set?

YES : Replace the ECM. When the ECM is replaced,

register the ID code. Refer to GROUP 42B, Diagnosis
− ID Codes Registration Judgment Table <Vehicles

with KOS>

P.42B-15

or GROUP 42C, Diagnosis

− ID

Codes Registration Judgment Table <Vehicles with
WCM>

P.42C-10

. Then go to Step 11.

NO : It can be assumed that this malfunction is intermittent.

Refer to GROUP 00, How to Use Troubleshooting/
Inspection Service Points

− How to Cope with

Intermittent Malfunctions

P.00-15

.

STEP 11. Using scan tool MB991958, read the diagnostic
trouble code (DTC).

CAUTION

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 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 P0606 set?

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

DTC P060B: Internal Control Module A/D Processing Performance Problem

.

TECHNICAL DESCRIPTION

Monitors whether input voltage from the accelerator
pedal position sensor (sub) is normally converted
into a digital signal in the ECM.

.

MONITOR EXECUTION

Continuous

.

MONITOR EXECUTION CONDITIONS
(Other monitor and Sensor)

Other Monitor (There is no temporary DTC stored

in memory for the item monitored below)

• Not applicable

Sensor (The sensor below is determined to be

normal)

• Not applicable

.

DTC SET CONDITIONS

Check Condition

• Ignition switch is "ON" position.

Judgment Criterion

• When the input voltage from the accelerator

pedal position sensor (sub) is periodically 0 V for
0.45 second, the digital value of the input voltage
indicates 0.2 V or more.

.

OBD-II DRIVE CYCLE PATTERN

None.

.

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

• ECM failed.
