Diagnostic Procedure

WARNING: This page is about a different car, the 2016 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.

Step	Inspection		Action
1	VERIFY SAS CONTROL MODULE DTCs Perform the DTC inspection for the SAS control module using the M-MDS. (See DTC INSPECTION [STANDARD DEPLOYMENT CONTROL SYSTEM] .) (See DTC INSPECTION [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [STANDARD DEPLOYMENT CONTROL SYSTEM] .) (See DTC TABLE [TWO-STEP DEPLOYMENT CONTROL SYSTEM] .)
1		No	Go to the next step.
2	INSPECT SAS CONTROL MODULE CONNECTOR Switch the ignition to off. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Disconnect the SAS control module connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
2		No	Repair or replace the connector, then go to Step 7.
3	INSPECT REAR BODY CONTROL MODULE (RBCM) CONNECTOR Switch the ignition to off. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Disconnect the rear body control module (RBCM) connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
3		No	Repair or replace the connector, then go to Step 7.
4	INSPECT FOR SHORT TO GROUND BETWEEN WIPER SWITCH AND REAR BODY CONTROL MODULE (RBCM) Switch the wiper switch off. Inspect for continuity between rear body control module (RBCM) terminal 3R and body ground. Is there continuity?	Yes	Repair or replace the wiring harness, then go to Step 7.
4		No	Go to the next step.
5	INSPECT WIRING HARNESS BETWEEN WIPER SWITCH AND REAR BODY CONTROL MODULE (RBCM) FOR OPEN CIRCUIT Disconnect the rear body control module (RBCM) connector. Disconnect the start stop unit connector. Inspect for continuity between rear body control module (RBCM) terminal 3R and SAS control module terminal 2B. Is there continuity?	Yes	Repair or replace the wiring harness, then go to Step 7.
5		No	Go to the next step.
6	INSPECT FOR SHORT TO POWER SUPPLY BETWEEN WIPER SWITCH AND REAR BODY CONTROL MODULE (RBCM) Verify that the start stop unit and rear body control module (RBCM) connectors are disconnected. 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 or on). Measure the voltage at rear body control module (RBCM) terminal 3R (vehicle wiring harness side). Is the voltage 0 V ?	Yes	Go to the next step.
6		No	Repair or replace the wiring harness and go to the next step.
7	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Reconnect all the disconnected connectors. Reconnect the disconnected negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Clear rear body control module (RBCM) DTCs using the M-MDS. (See CLEARING DTC [REAR BODY CONTROL MODULE (RBCM)] .) Perform the DTC inspection for the rear body control module (RBCM) using the M-MDS. (See DTC INSPECTION [REAR BODY CONTROL MODULE (RBCM)] .) Is DTC B1207:86 displayed?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the rear body control module (RBCM), then go to the next step. (See REAR BODY CONTROL MODULE (RBCM) REMOVAL/INSTALLATION .)
7		No	Go to the next step.
8	VERIFY IF OTHER DTCs DISPLAYED Are any other DTCs displayed?	Yes	Repair the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [REAR BODY CONTROL MODULE (RBCM)] .)
8		No	DTC troubleshooting completed.
