DTC P1D64 (143)

DTC P1D64  : Collision Detection Signal Circuit

NOTE:  Before you troubleshoot, review the general troubleshooting information .

DTC (Electric Powertrain)

1. Problem verification

   -1. Turn the vehicle to the ON mode.

   -2. Clear the DTC with the HDS.

   -3. Turn the vehicle to the OFF (LOCK) mode.

   -4. Turn the vehicle to the ON mode.

   -5. Check for Pending or Confirmed DTCs with the HDS.

   P1D64 Collision Detection Signal Circuit

   Is DTC P1D64 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

2. SRS indicator check

   -1. Turn the vehicle to the OFF (LOCK) mode, then wait for 10 seconds.

   -2. Turn the vehicle to the ON mode, and check that the SRS indicator comes on.

   Does the SRS indicator come on?

   YES 

   Go to SRS troubleshooting .

   NO 

   Go to step 3.

3. Determine possible failure area (SRS unit, CDS line)

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

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

   -3. Wait at least 3 minutes.

   -4. Disconnect the following connector.

   SRS unit connector A (39P)

   -5. Do the 12 volt battery terminal reconnection procedure .

   -6. Turn the vehicle to the ON mode.

   -7. Measure the voltage between test points 1 and 2.

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

   Is there about 5.0 V?

   YES 

   The CDS wire is OK. Faulty SRS unit or poor connection at SRS unit connector A (39P) and the SRS unit; check the connection. If the connection is OK, replace the SRS unit .

   NO 

   Go to step 4.

4. Shorted wire check (CDS line)

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

   -2. Remove the service plug and the IPU cover .

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

   Test condition	Vehicle OFF (LOCK) mode
   	Battery condition monitor module connector E (32P): disconnected
   	SRS unit connector A (39P): disconnected
   Test point 1	Battery condition monitor module connector E (32P) No. 30

   Test point 2

   Body ground

   Is there 1 MΩ or more?

   YES 

   Go to step 5.

   NO 

   Repair a short in the CDS wire between the battery condition monitor module (E30) and the SRS unit.

5. Open wire check (CDS line)

   -1. Connect terminals A and B with a jumper wire.

   Terminal A	SRS unit connector A (39P) No. 1
   Terminal B	Body ground

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

   Test condition	Vehicle OFF (LOCK) mode
   	Battery condition monitor module connector E (32P): disconnected
   	SRS unit connector A (39P): disconnected
   	SRS unit connector A (39P) No. 1: jumped to body ground
   Test point 1	Battery condition monitor module connector E (32P) No. 30
   Test point 2	Body ground

   Is there 1.0 Ω or less?

   YES 

   The CDS wire is OK. Replace the battery condition monitor module .

   NO 

   Repair an open in the CDS wire between the battery condition monitor module (E30) and the SRS unit.
