?1.
Turn the vehicle to the ON mode.
?2.
Clear the DTC with the HDS.
?3.
Start the engine, and warm it up to normal operating temperature (the radiator fan comes on twice).
?4.
Test-drive the vehicle in D on a flat road at speeds about 37 mph (60 km/h) for at least 10 seconds.
?5.

DTC Description
Confirmed DTC
Pending DTC
Freeze Frame
P0976 Shift Solenoid Valve B Circuit Low
Is DTC P0976 indicated?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between the shift solenoid valve B and the PCM. 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.
IG1 MISS SOL line check:
IG1 MISS SOL line check
?1.
Turn the vehicle to the OFF (LOCK) mode.
?2.
Jump the SCS line with the HDS, and wait more than 1 minute.
NOTE: This step must be done to protect the PCM from damage.
Check for a blown No. D4 (10 A) fuse in the under-dash fuse/relay box. If the fuse is blown, replace it. If the fuse blows again, repair a short in the No. D4 (10 A) fuse circuit. If the fuse is OK, repair an open in the IG1 MISS SOL wire between the PCM and the under-dash fuse/relay box.?
3.
Shift solenoid valve B check:
Shift solenoid valve B check
?1.
Turn the vehicle to the OFF (LOCK) mode.
?2.
Jump the SCS line with the HDS, and wait more than 1 minute.
NOTE: This step must be done to protect the PCM from damage.
?3.
Disconnect the following connector.
PCM connector C (51P)
?4.
Measure the resistance between test points 1 and 2.
The shift solenoid valve B is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or replace the original PCM.?
NO
Go to step 4.
4.
Shorted wire check (SOL B line):
Shorted wire check (SOL B line)
?1.
Disconnect the following connector.
Solenoid wire harness A 8P connector
?2.
Check for continuity between test points 1 and 2.
Test condition
Vehicle OFF (LOCK) mode
Solenoid wire harness A 8P connector: disconnected
Shift solenoid valve B is OK. Repair a short to body ground in the SHB+ wire between the solenoid wire harness A 8P connector and shift solenoid valve B.?
