1. Turn the ignition switch to LOCK (0).
2. Jump the SCS line with the HDS.
3. Disconnect ECM/PCM connector A (44P), then
disconnect the HDS.
4. Measure the resistance between ECM/PCM connector terminals A36 and A37.
Go to step 41.
Go to step 5. 5. Disconnect the gauge control module (tach) 36P
connector (see page 22- 277).
6. Disconnect the ABS modulator-control unit 25P connector (see page 19-90) (or the VSA modulator-
control unit 37P connector (see page 19-171) and
the yaw rate-lateral acceleration sensor 4P
connector (see page 19-169)).
7. Disconnect SRS unit connector A (28P) (see page 24-203).
8. Disconnect EPS control unit connector D (28P) (see page 17-84).
9. With TPMS: Disconnect the TPMS control unit 20P connector (see page 18-75).

34. Measure the resistance between ECM/PCM
connector terminals A36 and A37.
Go to step 35.
Substitute a known-good SRS unit (see page
24-203). If the HDS identifies the vehicle, replace
the original SRS unit (see page 24-203).
35. Disconnect SRS unit connector A (28P).
36. Reconnect EPS control unit connector D (28P). 37. Measure the resistance between ECM/PCM
connector terminals A36 and A37.
With TPMS: Go to step 38.
Without TPMS: Update the ECM/PCM if it does not have the latest software (see page 11-227), or
substitute a known-good ECM/PCM (see page
11-7), then recheck. If the symptom/indication
goes away with a known-good ECM/PCM,
replace the original ECM/PCM (see page 11-228).
Substitute a known-good EPS control unit
(see page 17-84). If the HDS identifies the vehicle,
replace the original EPS control unit (see page
17-84).

38. Disconnect EPS control unit connector D (28P).
39. Reconnect the TPMS control unit 20P connector.
40. Measure the resistance between ECM/PCM
connector terminals A36 and A37.
Update the ECM/PCM if it does not have the
latest software (see page 11-227), or substitute a
known-good ECM/PCM (see page 11-7), then
recheck. If the symptom/indication goes away with
a known-good ECM/PCM, replace the original ECM/
PCM (see page 11-228).
Substitute a known-good TPMS control unit
(see page 18-75). If the HDS identifies the vehicle,
replace the original TPMS control unit (see page
18-75). 41. Disconnect the gauge control module (tach) 36P
connector (see page 22- 277).
42. Disconnect the ABS modulator-control unit 25P connector (see page 19-90) (or the VSA modulator-
control unit 37P connector (see page 19-171) and
the yaw rate-lateral acceleration sensor 5P
connector (see page 19-169)).
43. Disconnect SRS unit connector A (28P) (see page 24-203).
44. Disconnect EPS control unit connector D (28P) (see page 17-84).
45. With TPMS: Disconnect the TPMS control unit 20P connector (see page 18-75).
