Determination Procedure

CAUTION:

When disconnecting the connector, verify that there is no looseness, damage, deformation, corrosion, or poor connection of the connector terminals.
When inspecting the DLC-2, touch it with a paper clip or similar thin pin without directly inserting a tester into the terminals.
Disconnect the negative battery cable before performing any work that requires handling of connectors.

DETERMINATION PROCEDURE DESCRIPTION

Step	Inspection		Action
1	INSPECT BETWEEN CONNECTOR C-34 AND INSTRUMENT CLUSTER FOR SHORT BETWEEN CIRCUITS Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] ) Disconnect connector C-34. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] ) Switch the ignition ON (engine off). Measure the voltage at instrument cluster terminals C and E. Is the voltage at instrument cluster terminals C and E the same?	Yes	Go to the next step.
1		No	Go to Step 3.
2	INSPECT INSTRUMENT CLUSTER FOR SHORT BETWEEN CIRCUITS Switch the ignition off. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] ) Disconnect the instrument cluster connector. Inspect for continuity between instrument cluster terminals C and E (wiring harness side). Is there continuity?	Yes	Repair or replace the wiring harness between the instrument cluster and connector C-34 because the wiring harness is shorted between circuits.
2		No	Replace the instrument cluster because there is a short between circuits in the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION )
3	INSPECT JB No. FOR SHORT BETWEEN CIRCUITS Disconnect connector C-33. Connect connector C-34. Inspect for continuity between instrument cluster terminals C and E (wiring harness side). Is there continuity?	Yes	Replace the JB No. because there is a short between circuits in the JB No..
3		No	Go to the next step.
4	INSPECT BETWEEN CONNECTOR C-33 AND DLC-2 FOR SHORT BETWEEN CIRCUITS Inspect for continuity between DLC-2 terminals L and K. Is there continuity?	Yes	Repair or replace the wiring harness between connector C-33 and DLC-2 because the wiring harness is shorted between circuits.
4		No	Go to the next step.
5	INSPECT BETWEEN CONNECTOR C-33 AND CLIMATE CONTROL UNIT FOR SHORT BETWEEN CIRCUITS Inspect for continuity between climate control unit terminals D and B. Is there continuity?	Yes	Go to the next step.
5		No	Go to Step 7.
6	INSPECT CLIMATE CONTROL UNIT FOR SHORT BETWEEN CIRCUITS Disconnect the climate control unit connector. Inspect for continuity between climate control unit terminals D and B (wiring harness side). Is there continuity?	Yes	Repair or replace the wiring harness between the climate control unit and connector C-33 because the wiring harness is shorted between circuits.
6		No	Replace the climate control unit because there is a short between circuits inside the climate control unit. (See CLIMATE CONTROL UNIT REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER] )
7	INSPECT BETWEEN CONNECTOR C-08 AND CONNECTOR C-33 FOR SHORT BETWEEN CIRCUITS Disconnect connector C-08. Connect connector C-33. Inspect for continuity between DLC-2 terminals L and K. Is there continuity?	Yes	Repair or replace the wiring harness between connector C-08 and connector C-33 because the wiring harness is shorted between circuits.
7		No	Go to the next step.
8	INSPECT BETWEEN BSM CONTROL MODULE (LH) AND REAR BODY CONTROL MODULE (RBCM) FOR SHORT BETWEEN CIRCUITS Disconnect the rear body control module (RBCM) connector. Inspect the continuity between BSM control module (LH) terminals C and D. Is there continuity?	Yes	Go to the next step.
8		No	Go to Step 11.
9	INSPECT BETWEEN BSM CONTROL MODULE (LH) AND CONNECTOR C-19 FOR SHORT BETWEEN CIRCUITS Disconnect connector C-19. Inspect the continuity between BSM control module (LH) terminals C and D. Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness between the rear body control module (RBCM) and connector C-19 because the wiring harness is shorted between circuits.
10	INSPECT BSM CONTROL MODULE (LH) FOR SHORT BETWEEN CIRCUITS Disconnect the BSM control module (LH) connector. Inspect for continuity between BSM control module (LH) terminals C and D (wiring harness side). Is there continuity?	Yes	Repair or replace the wiring harness between the BSM control module (LH) and connector C-19 because the wiring harness is shorted between circuits.
10		No	Replace the BSM control module (LH) because there is a short between circuits in the BSM control module (LH). (See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION )
11	INSPECT REAR BODY CONTROL MODULE (RBCM) FOR SHORT BETWEEN CIRCUITS Inspect for continuity between rear body control module (RBCM) terminals 3E and 3G (wiring harness side). Is there continuity?	Yes	Repair or replace the wiring harness between the rear body control module (RBCM) and connector C-08 because the wiring harness is shorted between circuits.
11		No	Replace the rear body control module (RBCM) because there is a short between circuits in the rear body control module (RBCM). (See REAR BODY CONTROL MODULE (RBCM) REMOVAL/INSTALLATION )
