VEHICLE TECHNICAL INFO

NOTE: The √ mark indicates an article is being repeated from a previous issue of Tech Talk due to the subject's importance.

GROUP 35C - Active Stability Control System (ASC)

FLUID SEEPAGE AT ABS HYDRAULIC UNIT - 2015 Outlander Sport/RVR, 2016 Lancer, 2016 Outlander.

If, during diagnosis, you suspect fluid seepage from the area of the ABS hydraulic unit, before replacing any parts please thoroughly clean the fluid residue and inspect for seepage at the six line fittings while the brake pedal is applied. If seepage at a line fitting is suspected, slightly loosen the fitting and then re-torque the fitting to the specification listed in the Service Manual. After properly torquing the line fittings, recheck for seepage with the brake pedal applied. Do not replace the ABS hydraulic unit for a line fitting concern unless recommended to do so by TechLine.

ABS WHEEL SPEED SENSOR REPLACEMENT - 2014-17 Mirage, 2017 Mirage G4.

When replacing a front or rear ABS (wheel speed) sensor on a 2014-17 Mirage or Mirage G4 (for DTCs C1201-C1216), please replace it together with the corresponding wheel hub bearing (even if there is no apparent problem with the wheel hub bearing).

MMNA is investigating these components as a paired set. A Warranty Parts Return Request will be issued for all Mirage ABS sensors. A note should be added to the warranty claim that states the wheel hub bearing was replaced in accordance with this Tech Talk article.

MMNA requests the removed ABS sensor and corresponding wheel hub bearing are NOT WIPED CLEAN prior to packaging them for return. MMNA will announce (in a future Tech Talk article) when it is no longer necessary to replace the wheel hub bearing when the ABS sensor is replaced.

DTC C1505: STEERING ANGLE SENSOR ERROR - 2014-17 Mirage, 2017 Mirage G4.

When diagnosing a vehicle with the check engine light ON for DTC C1505 (steering angle sensor error) please refer to the troubleshooting steps in the Service Manual and follow the steps precisely. Erasing the DTC and recalibrating the steering angle sensor usually fixes the vehicle. Do NOT replace the steering angle sensor unless it fails the performance test as described in the Service Manual.

GROUP 52B - Supplemental Restraint System

√ DRIVER'S SEAT SLIDE SENSOR WIRING HARNESS DAMAGE UNDER DRIVER'S SEAT WITH DTC B1556 - 2013-15 Outlander Sport/RVR.

NOTE: This article is being reprinted to point out a part number supersession: P/N 6979A429 has been superseded by P/N 6979A394.

As published in TIN-15-52B-001, MMNA has identified warranty claims for SRS DTCs B1558 (Occupant Classification-ECU DTC Present) and B1556 (Driver's Seat Slide Sensor Malfunction [Occupant Classification-ECU]) with OCM DTC B1B8D (Driver's Seat Slide Sensor Open Circuit). Additional OCM DTCs that may also be present are: B1B8C (Driver's Seat Slide Sensor Circuit Performance) and B1B8E (Driver's Seat Slide Sensor Short Circuit).

During diagnosis, technicians should check for damage to the driver's seat slide position sensor harness in the location shown below.

If a damaged harness is found, DO NOT replace the front seat adjustor or SRS ECU for this condition. The harness is now shown in CAPS and is available as P/N 6979A394 .

NOTE: On MUT-III, the SRS DTC B1556 is defined as "Drivers seat position SW fail."

Additionally, wiring for the seat belt buckle switch, heated seat, and power seat motor (if equipped) are found in the same under-seat location as the harness for the driver's seat slide sensor. MMNA has identified claims for inoperative function or DTCs for the seat belt buckle switch (SRS DTC B1527 [Open], or B1528 [Short]), heated seat, and power seat motor that could also be related to wiring concerns under the driver's seat area. These components are not serviced with the front seat adjustor and are available separately as identified in CAPS. Please inspect these harnesses if inoperative functions or DTCs exist for the driver's seat belt buckle switch, heated seat, and/or power seat.

GROUP 54A - Chassis Electrical

DOOR LOCK ACTUATORS - Outlander Sport/RVR built after 8/1/2014.

Dealers are requested to submit a Product Quality Report (PQR) for door lock actuator concerns on vehicles built after 8/1/2014.

ETACS ECU INPUT TESTING: PULSE CHECKING SWS VEHICLES WITHOUT FULL SIZE VCI - 2000-12 Eclipse, 2001-12 Eclipse Spyder, 2004-11 Endeavor, 1999-12 Galant.

Dealer technicians checking the Simplified Wiring System (SWS) without a full size VCI (such as VCI LITE) do not have the capability to conduct a Pulse Check or use the SWS interface cartridge to test the SWS system.

Follow the steps below to test the system using a voltmeter.

Attach a jumper wire into pin 9 of the OBD-II diagnostic connector under the dash area. (use a terminal from the wiring repair kit so you will not damage the terminal in the Data Link Connector)
Attach the positive lead of the meter to the jumper wire.
Ground your other meter lead. (Pins 4 and 5 of the OBD-II connector may be used or a body ground.)
With all doors, hood, trunk or hatch closed, but unlocked, and key OUT of the ignition, the meter should have a fairly consistent reading onscreen.
When any door, hood, or rear lid is opened, its corresponding switch will close. This momentarily changes the voltage on the meter. This means the ETACS ECU has seen the switch movement.
Other switches that can be tested are wiper, turn, lighting, and sunroof. Refer to Service Group 54 in the Service Manual for specific instructions and limitations.

NOTE: The type of meter used will be more or less obvious when the particular switch is closed, an Analog meter is visually the best. Digital meters with an analog bar also work well. ES2 class has reference material to Pulse checking if you have attended. Older Non-SWS vehicles have the testing ability, but diagnostic pin location varies.
