   DTC Description	DTC
   B1032 CDS (Collision detection signal) signal error

   Is DTC B1032 indicated?

   YES: with power tailgate

   Go to step 2.

   YES: without power tailgate

   Go to step 3.

   NO 

   Intermittent failure, the system is OK at this time.

2. Open wire check (B-CAN_H line, B-CAN_L line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Disconnect the following connectors.

   Body control module connector B (36P) Gauge control module connector A (32P)

   -3. Measure the resistance between test points 1 and 2.

   Test condition

   Vehicle OFF (LOCK) mode Body control module connector B (36P): disconnected Gauge control module connector A (32P): disconnected

   Circuit name	Test points 1		Test points 2
   	Connector	Terminal	Connector	Terminal
   B-CAN_H	Body control module connector B (36P)	No. 20	Gauge control module connector A (32P)	No. 30
   B-CAN_L		No. 21		No. 31

   Is there 1.0 Ω or less?

   YES 

   The B-CAN_H wire and the B-CAN_L wire are OK. Replace the gauge control module

   NO 

   Repair an open in the B-CAN_H wire and/or the B-CAN_L wire.

3. Open wire check (CDS line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Do the 12 volt battery terminal disconnection procedure , and wait for at least 3 minutes.

   -3. Disconnect the following connectors.

   Body control module connector D (40P)SRS unit connector A (39P)

   -4. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode Body control module connector D (40P): disconnected SRS unit connector A (39P): disconnected
   Test point 1	Body control module connector D (40P) No. 34
   Test point 2	SRS unit connector A (39P) No. 1

   Is there 1.0 Ω or less?

   YES 

   Go to step 4.

   NO 

   Repair an open or high resistance in the wire.

4. Shorted wire check (CDS line)

   -1. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode Body control module connector D (40P): disconnected SRS unit connector A (39P): disconnected
   Test point 1	SRS unit connector A (39P) No. 1
   Test point 2	Body ground

   Is there 1.0 MΩ or more?

   YES 

   The CDS wire is OK. Go to step 5.

   NO 

   Repair a short to ground in the wire.

5. Body control module check

   -1. Reconnect the following connector.

   Body control module connector D (40P)

   -2. Do the 12 volt battery terminal reconnection procedure .

   -3. Turn the vehicle to the ON mode.

   -4. Measure the voltage between test points 1 and 2.

   Test condition	Vehicle ON mode SRS unit connector A (39P): disconnected
   Test point 1	Body control module connector D (40P) No. 34
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   Replace the SRS unit .

   NO 

   Replace the body control module .
