connector MITSUBISHI ENDEAVOR 2004 Service User Guide

The amount of voltage generated at each wheel is determined by the clearance
between the ABS rotor teeth and the ABS sensor, and by the speed of rotation. Sends alternating current signals at frequencies which are proportional to the
rotation speeds of each wheel to the ABS electronic control unit (ABS-ECU). The ABS hydraulic unit modulates the amount of braking force individually
applied to each wheel cylinder.
ABS DTC SET CONDITIONS The ABS-ECU monitors voltage fluctuation in each ABS sensor circuit. If the ECU
detects short or open circuit in the circuit, it will set a diagnostic trouble code. TROUBLESHOOTING HINTS (THE MOST LIKELY CAUSES FOR THESE DTCS ARE TO SET ARE:)
Current trouble
Malfunction of the ABS sensor Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with ABS-ECU)
Past trouble
Carry out diagnosis with particular emphasis o connector(s) or wiring harness
in ABS sensor circuit. For diagnosis procedures, refer to HOW TO USE TROUBLESHOOTING/ INSPECTION SERVIC
).
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
MB991970: ABS Check Harness
STEP 1. Using scan tool MB991958, diagnose the CAN bus line.

2. Start the engine.
3. Set scan tool MB991958 to the data reading mode, and check the data list
items by driving the vehicle.
Item 01 (DTC C1200 is set): Front right ABS sensor Item 02 (DTC C1205 is set): Front left ABS sensor Item 03 (DTC C1210 is set): Rear right ABS sensor Item 04 (DTC C1215 is set): Rear left ABS sensor
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Does the speedometer indication match the scan tool indication?
YES: It can be assumed that this malfunction is intermittent. Refer to
HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
.
NO: Go to Step 4.
STEP 4. Measure the voltage 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. 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 C1200 is set: Between signal terminal 9 and body ground, and
between ground terminal 10 and body ground DTC C1205 is set: Between signal terminal 26 and body ground, and
between ground terminal 16 and body ground DTC C1210 is set: Between signal terminal 11 and body ground, and between
ground terminal 17 and bod
y ground NOTE: Do not connect special tool ABS Check Harness
(MB991970) to the ABS-ECU.

Q: Does the voltage measure 1 V or less?
YES: Go to Step 5.
NO (When the voltage between terminal 9 or 10 - and body ground
measures more than 1 V): Go to Step 7 .
NO (When the voltage between terminal 26 or 16 - and body ground
measures more than 1 V): Go to Step 9 .
NO (When the voltage between terminal 11 or 17 - and body ground
measures more than 1 V): Go to Step 11 .
NO (When the voltage between terminal 28 or 27 - and body ground
measures more than 1 V): Go to Step 13 .
STEP 5. 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. There should be no continuity.
DTC C1200 is set: Between signal terminal 9 and body ground, and
between ground terminal 10 and body ground DTC C1205 is set: Between signal terminal 26 and body ground, and
between ground terminal 16 and body ground DTC C1210 is set: Between signal terminal 11 and body ground, and
between ground terminal 17 and body ground DTC C1215 is set: Between signal terminal 28 and body ground, and between
ground terminal 27 and bod
y ground 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 7 .
YES (Continuity exists between terminal 26 or terminal 16 and body
ground): Go to Step 9 .
YES (Continuity exists between terminal 11 or terminal 17 and body
ground): Go to Step 11 .
YES (Continuity exists between terminal 28 or terminal 27 and body
ground): Go to Step 13 .
NO: Go to Step 6.
STEP 6. Measure the resistance at the 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 ABS-ECU connector terminals.
DTC C1200 is set: Between terminal 9 and terminal 10 DTC C1205 is set: Between terminal 26 and terminal 16 DTC C1210 is set: Between terminal 11 and terminal 17 DTC C1215 is set: Between terminal 28 and terminal 27
