15. Remove the jumper wire from ECM/PCM connector
A (44P).
16. Connect ECM/PCM connector terminal A37 to body
ground with a jumper wire.
17. Check for continuity between gauge control
module (tach) 36P connector terminal No. 19 and
body ground.
• With VSA system: Go to step 18.
• Without VSA system: Go to step 19.
Repair open in the wire between the ECM/
PCM (A37) and the gauge control module (tach).

20. Remove the jumper wire from ECM/PCM connector
A (44P).
21. Reconnect the gauge control module (tach) 36P
connector.
22. Measure the resistance between ECM/PCM
connector terminals A36 and A37.
• With ABS: Go to step 23.
• With VSA system: Go to step 26.
Substitute a known-good gauge control
module (tach) (see page 22-277). If the HDS
identifies the vehicle, replace the original gauge
control module (tach) (see page 22-277).
23. Disconnect the gauge control module (tach) 36P
connector.
24. Reconnect the ABS modulator-control unit 25P
connector.
25. Measure the resistance between ECM/PCM
connector terminals A36 and A37.
Disconnect the ABS modulator-control unit
25P connector, then go to step 33.
Substitute a known-good ABS modulator-
control unit (see page 19-90). If the HDS identifies
the vehicle, replace the original ABS modulator-
control unit (see page 19-90).
26. Disconnect the gauge control module (tach) 36P
connector.
27. Reconnect the VSA modulator-control unit 37P
connector.

Go to step 29.
Substitute a known-good VSA modulator-
control unit (see page 19-171). If the HDS identifies
the vehicle, replace the original VSA modulator-
control unit (see page 19-171).
29. Disconnect the VSA modulator-control unit 37P
connector.
30. Reconnect the yaw rate-lateral acceleration sensor
5P connector.
31. Measure the resistance between ECM/PCM
connector terminals A36 and A37.
Go to step 32.
Substitute a known-good yaw rate-lateral
acceleration sensor (see page 19-169). If the HDS
identifies the vehicle, replace the original yaw rate-
lateral acceleration sensor (see page 19-169).
32. Disconnect the yaw rate-lateral acceleration sensor
5P connector.
33. Reconnect SRS unit connector A (28P).
