SRS Indicator Lamp On
If you receive customer reports in the above model vehicles that the SRS light is illuminated and diagnostic fault code(s) B1035, B1037, B103B and/or B1039 are stored in the SRS ECU, the resistance in R12/11, R12/12, R12/20 or R12/21 ignition circuits for the sidebag squibs may be too high. This high resistance is caused by either of the following:
^ The left front door separation point connector X35/1,
^ The right front door separation point connector X35/2,
^ The left rear door separation point connector X35/3
^ The right rear door separation point connector X35/4.
To resolve, remove connectors from the wires for sidebags in the left and right front footwells and the left and right rear entry ways and connect wires directly. Please follow the below procedure to repair.
Note:
Always perform procedure on all 4 connectors.
1. Remove ignition key.
2. Remove A-pillar paneling in front foot well and door sill molding. Remove left front floor covering per WIS document AR68.20-P-2050P and right front floor covering per WIS document AR68.20-P-2070P.
3. Remove left and right rear door sill molding.
4. Expose wiring harness. Figure 1 shows connector for front doors X35/1 (left front door separation door separation point) and X35/2 (right rear door separation point) are similar. Wiring diagram of airbag control module with integrated E-call system can be found in WEB ETM document 91.60-U-2101FA.
5. Remove connectors and connect wires directly with solder connectors.
a. Cut line approx. 10 mm in front of and behind connector.
b. Remove about 20 mm of fabric tape on the control unit side.
c. Strip about 15 mm of insulation from the wire.
d. Slide solder connector onto wires.
e. Twist both wire ends together, observing the wire color assignment.
f. Position solder connector in the middle and shrink it on (solder) using a heat gun.
^ Utilize wiring harness repair set W220 589 02 99 00 and heat gun part no. 458-HL1802E via the MBUSA Standard Service Equipment Program.
g. Inspect solder connection.
h. Tape up both ends of the wires.
