ECU MITSUBISHI ENDEAVOR 2004 Service Owner's Guide

2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between the relevant signal and ground terminals in
the ABS sensor circuit and body ground. It should be less than 1V.
DTC C1201 is set: Between signal terminal 9 and body ground, and
between ground terminal 10 and body ground DTC C1206 is set: Between signal terminal 26 and body ground, and
between ground terminal 16 and body ground DTC C1211 is set: Between signal terminal 11 and body ground, and
between ground terminal 17 and body ground DTC C1216 is set: Between signal terminal 28 and body ground, and
between ground terminal 27 and body ground
Q: Does the voltage measure 1 V or less?
YES: Go to Step 9.
NO (When the voltage between terminal 9 or 10 - and body ground
measures more than 1 V): Go to Step 11 .
NO (When the voltage between terminal 26 or 16 - and body ground
measures more than 1 V): Go to Step 12 .
NO (When the voltage between terminal 11 or 17 - and body ground
measures more than 1 V): Go to Step 13 .
NO (When the voltage between terminal 28 or 27 - and body ground
measures more than 1 V): Go to Step 14 .
STEP 9. Measure the resistance at ABS-ECU connector A-02.
1. Disconnect the connector A-02, and connect special tool ABS Check
Harness (MB991970) to the wiring harness-side connector.
2. Measure the resistance between the relevant signal and ground terminals
in the ABS sensor circuit and body ground. OK if there is no continuity. DTC C1201 is set: Between signal terminal 9 and bo
dy ground, and NOTE: Do not connect special tool ABS Check Harness
(MB991970) to the ABS-ECU.

Q: Does continuity exist?
YES (Continuity exists between terminal 9 or terminal 10 and body
ground): Go to Step 11 .
YES (Continuity exists between terminal 26 or terminal 16 and body
ground): Go to Step 12 .
YES (Continuity exists between terminal 11 or terminal 17 and body
ground): Go to Step 13 .
YES (Continuity exists between terminal 28 or terminal 27 and body
ground): Go to Step 14 .
NO: Go to Step 10.
STEP 10. Measure the resistance at ABS-ECU connector A-02.
1. Disconnect the connector A-02, and connect special tool ABS Check
Harness (MB991970) to the wiring harness-side connector.
2. Measure the resistance between the relevant signal and ground terminals
in the ABS sensor circuit.
DTC C1201 is set: Between signal terminal 9 and ground terminal 10 DTC C1206 is set: Between signal terminal 26 and ground terminal
16 DTC C1211 is set: Between signal terminal 11 and ground terminal
17 DTC C1216 is set: Between signal terminal 28 and ground terminal
27
Standard Value: 1.24 - 1.64 kohm NOTE: Do not connect special tool ABS Check Harness
(MB991970) to the ABS-ECU.

Q: Is the resistance between terminals 16 and 26, 9 and 10, 27 and 28, or
11 and 17 within the standard value?
YES (When resistance between all terminals are within the standard
value): Go to Step 15 .
NO (When resistance between terminals 9 and 10 is not within the
standard value): Go to Step 11.
NO (When resistance between terminals 16 and 26 is not within the
standard value): Go to Step 12 .
NO (When resistance between terminals 11 and 17 is not within the
standard value): Go to Step 13 .
NO (When resistance between terminals 27 and 28 is not within the
standard value): Go to Step 14 .
STEP 11. Check ABS-ECU connector A-02 and ABS sensor < front: RH >
connector A-31 for loose, corroded or damaged terminals, or terminals
pushed back in the connector.

Q: Are ABS-ECU connector A-02 and ABS sensor < front: RH >
connector A-31 damaged?
YES: Repair or replace the damaged component(s). Then go to Step 16 .
NO: Open or short circuit may be present in the front right ABS sensor
circuit. Repair the wiring harness between ABS-ECU connector A-02
(terminals 9 and 10) and front right ABS sensor A-31 (terminals 2 and 1).
Then go to Step 16 .
STEP 12. Check ABS-ECU connector A-02 and ABS sensor < front: RH >
connector A-14 for loose, corroded or damaged terminals, or terminals
pushed back in the connector.
