The knock control system adjusts the ignition timing to
minimize knock.
The MAP sensor converts manifold absolute pressure
into electrical signals to the ECM/PCM.
The vehicle has certain readiness codes that are part of
the on-board diagnostics for the emissions systems. If
the vehicle’s battery has been disconnected or gone
dead, if the DTCs have been cleared, or if the ECM/PCM
has been reset, these codes are reset. In some states,
part of the emissions testing is to make sure these
codes are set to complete. If all of them are not set to
complete, the vehicle may fail the test, or the test
cannot be finished.
To check if the readiness codes are set to complete,
turn the ignition switch to ON (II), but do not start the
engine. The MIL will come on for 15 20 seconds. If it
then goes off, the readiness codes are complete. If it
flashes five times, one or more readiness codes are not
complete. To set each code, drive the vehicle or run the
engine as described in the procedures (see page 11-69). The mass air flow (MAF) sensor/intake air temperature
(IAT) sensor contains a hot wire sensor, a cold wire
sensor, and a thermistor. It is located in the intake air
passage. The resistance of the hot wire sensor, the cold
wire sensor, and the thermistor change due to intake air
temperature and air flow. The control circuit in the MAF
sensor controls the current to keep the hot wire at a set
temperature. The current is converted to voltage in the
control circuit, then output to the ECM/PCM.
This sensor detects countershaft speed.

How to Set Readiness Codes
The vehicle has certain readiness codes that are part of
the on-board diagnostics for the emissions systems. If
the vehicle’s battery has been disconnected or gone
dead, if the DTCs have been cleared, or if the ECM/PCM
has been reset, these readiness codes are reset to
incomplete. In some states, part of the emissions
testing is to make sure these codes are set to complete.
If all of them are not set to complete, the vehicle may
fail the emission test, or the test cannot be finished.
To check if the readiness codes are set to complete,
turn the ignition switch to ON (II), but do not start the
engine. The MIL will come on for 15 20 seconds. If it
then goes off, the readiness codes are set to complete.
If it flashes five times, one or more readiness codes are
not set to complete. To set readiness codes from
incomplete to complete, do the procedure for the
appropriate code.
To check the status of a specific DTC system, check the
OBD status in the DTC MENU with the HDS (see page
11-8). This screen displays the code, the current data list
of the enable criteria, and the status of the readiness
testing. NOTE:
 Do not turn the ignition switch to LOCK (0) or ACC (I) during the procedure.
 All readiness codes are cleared when the battery is disconnected, if the DTCs have been cleared, or if the
ECM/PCM is reset with the HDS.
 Low ambient temperatures or excessive stop-and-go traffic may increase the drive time needed to switch
the readiness code from incomplete to complete.
 The readiness code will not switch to complete until all the enable criteria are met.
 If a fault in the secondary HO2S system caused the MIL to come on, the readiness code cannot be set to
complete until you correct the fault.
 ECT SENSOR 1 at 70 °C (158 °F) or more.
 IAT SENSOR at 7 °C (20 °F) or more.
 Vehicle speed (VSS) above 40 km/h (25 mph). 1. Connect the HDS to the vehicle’s data link connector (DLC), and bring up the READINESS
CODEs screen for Catalyst in the DTCs MENU.
2. Start the engine.
3. Test-drive the vehicle under stop-and-go conditions with short periods of steady cruise. After about
8 km (5 miles), the readiness code should switch to
complete.
4. If the readiness code is still not set to complete, check for a Temporary DTC with the HDS. If there is
no DTC, one or more of the enable criteria were
probably not met; repeat the procedure.

DTC (Diagnostic Trouble Codes) Reading the DTC
Precautions
24-22SRS
General Troubleshooting Information
A
The self-diagnostic function of the SRS system allows it
to locate the causes of system problems and store this
information in memory. For easier troubleshooting, this
data can be retrieved via a data link circuit.
 When you turn the ignition switch to ON (II), the SRS indicator comes on. If it goes off after 6 seconds, the
system is normal, and is not currently detecting any
abnormality.
 If there is an abnormality, the system locates and defines the problem, stores this information in
memory, and turns on the SRS indicator. The data
remains in memory even if the ignition switch is
turned off or the battery is disconnected.
 The data is stored in memory as a diagnostic trouble code (DTC).
 The ‘‘x’’ at the end of each DTC denotes a numeric character (0 thru 9) or an alpha character (A thru F)
that is displayed on the HDS.
 DTCs are either latching or resetting depending on the malfunction. With resetting DTCs, the SRS
indicator goes off the next time the ignition switch is
turned to ON (II), and the system is normal, but the
DTC is still stored. With latching DTCs, the SRS
indicator does not turn to LOCK (0) until the
malfunction is repaired and the DTC is cleared.
 When you connect the HDS to the data link connector (DLC), you can retrieve a more detailed DTC in the
HDS ‘‘SRS’’ menu.
NOTE: Only read DTCs from the SRS menu, not from
the SWS menus. SWS (ODS unit) DTCs are subcodes
of SRS unit DTCs. Only troubleshoot the
corresponding SRS DTCs.
 After reading and recording the DTC, proceed with the troubleshooting procedure for that code.
 Use only a digital multimeter to check the system. Make sure its output is 10 mA (0.01 A) or less when
switched to the smallest value in the ohmmeter range.
A tester with a higher output could damage the
airbag circuit or cause accidental airbag deployment
and possible injury.  Whenever the ignition switch is in ON (II), or has been
turned to LOCK (0), for less than 3 minutes, be careful
not to bump the SRS unit; the airbags could
accidentally deploy and cause damage or injuries.
 Before removing the dashboard wire harness, floor wire harness, disconnect the driver’s airbag
connector, the front passenger’s airbag connector,
both side airbag connectors, both side curtain airbag
connectors and both seat belt tensioner connectors.
 Make sure the battery is fully charged. If the battery is dead or low, electrical measurements may not be
correct.
 Do not touch a tester probe to the terminals in the SRS unit or harness connectors, and do not connect
the SRS unit terminals or the sensor terminals with a
jumper wire. Use only the backprobe set and the
multimeter. Backprobe spring-loaded lock type
connectors correctly.
1. Make sure the ignition switch is in LOCK (0).
2. Connect the HDS to the data link connector (DLC) (A).
3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate,
troubleshoot the DLC circuit (see page 11-204).

SRS Unit Control Operation Recorded
NOTE:
 Before doing this troubleshooting procedure, review SRS Precautions and Procedures (see page 24-13)
and General Troubleshooting Information (see page
24-22).
 Before troubleshooting any of these DTCs, check the battery/system voltage and battery cable connections.
If the voltage is low, repair the charging system or
replace the battery before troubleshooting the SRS. If
the battery/system voltage is now OK, ask the client if
the battery ever went dead or if the engine was
started and run with the battery in a low state of
changed. A dead battery may trigger one or more of
these DTCs.
1. Clear the DTC memory (see page 24-23).
2. Turn the ignition switch to ON (II), and check that the SRS indicator comes on for about 6 seconds
and then goes off.
Replace the SRS unit (see page 24-203).
