10. Make sure the shift lever is in N or P (A/T model) orneutral (M/T model), then disconnect the engine
wire harness 1P connector (A). Connect a jumper
wire from the battery positive terminal to the
starter subharness 1P connector (B).
Go to step 11.
Check the starter subharness. If the wire is OK,
remove the starter (see page 4-10), then repair or
replace (see page 4-13) it as necessary. 11. Check the following items in the order listed until
you find the problem circuit:
NOTE: After the open circuit or high resistance in
the circuit is found and repaired, go to step 14.
 Check for an open or short in the YEL wire and connectors between the driver’s under-dash
fuse/relay box and the ignition switch.
 Check for an open or short in the RED wire and connectors between the under-dash fuse/relay
box and the engine wire harness 1P connector.
 Check for an open or short in the ORN wire and connectors between the under-dash fuse/relay
box and the clutch interlock switch (M/T model).
 Check for an open or short in the ORN wire, BLU/ WHT wire and connectors between the under-
dash fuse/relay box and the transmission range
switch (A/T model).
 Check for poor ground at G401 (M/T model) or G101 (A/T model).
 Check for a faulty ignition switch (see page 22-72).
 Check for a faulty clutch interlock switch (M/T model) (see page 4-8).
 Check for a faulty transmission range switch (A/T model) (see page 14-265).
 Check for a faulty starter cut relay (see page 22-70).

Cruise Control Input Test
NOTE: Always make sure that you have the latest Honda Diagnostic System (HDS) software before doing the input
tests.
1. Connect the HDS to the data link connector (DLC) (see step 2 on page 11-3).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain control module (PCM). If it does not communicate, troubleshoot the DLC circuit (see page 11- 204).
4. Go to PGM-FI, and check for DTCs (see page 11-3).
5. Do the following tests while monitoring parameters in the PGM-FI DATA LIST with the HDS. NOTE: Intermittent failures are often caused by loose circuit connections. While monitoring cruise control inputs,
flex the circuit wires, and note if any of the test results change.
