8. Check for continuity between park pin switch/A/Tgear position indicator panel light connector
terminal No. 3 and body ground.
Repair short to body ground in the wire
between park pin switch/A/T gear position indicator
panel light connector terminal No. 3 and the
MICU.
Go to step 9.
9. Shift the shift lever to P.
10. Check for continuity between park pin switch/A/T gear position indicator panel light connector
terminals No. 3 and No. 4. Do not push the shift
lever button.
Faulty park pin switch, replace the park pin
switch (see page 14-269).
Go to step 11. 11. Disconnect under-dash fuse/relay box connector F
(34P).
12. Turn the ignition switch to ON (II).
13. Measure the voltage between the No. 27 terminal of under-dash fuse/relay box connector F (34P) and
body ground.
Substitute a known-good MICU, and
recheck.
Repair or short in the wire between PCM
connector terminal B13, transmission range switch,
and MICU.

Low/High IG1-terminal Voltage
(Regular Diagnosis)
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0).
4. Start the engine.
5. Wait at least 60 seconds.
Go to step 6.
Check for loose terminals or poor connections.
If the connections are good, the system is OK at
this time.
6. Turn the ignition switch to LOCK (0).
7. Disconnect EPS control unit connector D (28P). 8. Turn the ignition switch to ON (II).
9. Wait at least 60 seconds.
10. Measure the voltage between EPS control unit connector D (28P) terminal No. 16 and body ground.
Check for loose terminals in the EPS control
unit connectors, and repair if necessary. If no poor
connections are found, replace the EPS control unit
(see page 17-84).
If there is no voltage, or the voltage is lower
than specified, repair an open or high resistance in
thewirebetweentheNo.4(7.5A)fuseinthe
under-dash fuse/relay box and the EPS control unit.
If the wire checks OK, check the battery (see page
22-67), and troubleshoot the alternator regulator
circuit (see page 4-28).

1. Turn the ignition switch to ON (II).
2. Check the BATTERY in the EPS DATA LIST with the
HDS.
Check for loose terminals or poor
connections. If the connections are good, the
system is OK at this time.
Go to step 3.
3. Turn the ignition switch to LOCK (0).
4. Check the No. 1 (70 A) fuse in the under-hood fuse/ relay box.
Reinstall the checked fuse, then go to step
13.
Go to step 5.
5. Disconnect the EPS control unit connector A (2P).
6. Check for continuity between EPS control unit connector A (2P) terminal No. 2 and body ground.
Repair short to body ground in the wire
between the EPS control unit and the No. 1 (70 A)
fuse in the under-hood fuse/relay box.
Install a new No. 1 (70 A) fuse in the under-
hood fuse/relay box, then go to step 7. 7. Reconnect the EPS control unit connector A (2P).
8. Turn the ignition switch to ON (II).
9. Clear the DTC with the HDS.
10. Turn the ignition switch to LOCK (0).
11. Start the engine.
12. Check for DTCs with the HDS.
Replace the EPS control unit (see page 17-84).
Troubleshooting is complete. If any other
DTCs are indicated, go to the indicated DTC’s
troubleshooting.
13. Disconnect EPS control unit connector A (2P) and connector D (28P).
14. Measure the voltage between EPS control unit connector A (2P) terminal No. 2 and body ground.
Check for loose terminals in the EPS control
unit connectors, and repair if necessary. If no poor
connections are found, replace the EPS control unit
(see page 17-84).
Repair open in the wire between the EPS
control unit and the No. 1 (70 A) fuse in the under-
hood fuse/relay box.

(see page 22-241). NOTE: Check for gauge DTCs with the HDS (see page
22-3). If gauge DTCs are stored, troubleshoot those
DTCs first.
1. Turn the ignition switch to LOCK (0).
2. Check the No. 4 (7.5 A) fuse in the under-dash fuse/ relay box.
Reinstall the checked fuse, then go to step 5.
