DIAGNOSTIC TROUBLE CODE (DTC) P1813

CLUTCH SWITCH PLAUSIBILITY

Circuit Description

Clutch switch plausibility diagnosis detects whether no
clutch switch signal detects in the corresponding range
(vehicle speed, engine speed) and engine load exceeds
upper load threshold for more than minimum time.

Conditions for Setting the DTC

•••••

DTCs P0101, P0102, P0103, P0335, P0336 and
P0501 are not set.

•••••

Vehicle speed is less than 2.4 km/h.

•••••

Ignition status is on.

•••••

Engine speed is less than 1800 rpm.

•••••

Engine load is greater than 0.6 for more than 5
seconds.

•••••

Start end is reached.

Action Taken When the DTC Sets

•••••

The Malfunction Indicator Lamp (MIL) will illuminate
after two consecutive driving cycles in which the diag-
nostic runs with the fault active.

•••••

The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.

•••••

A history DTC is stored.

Conditions for Clearing the MIL/DTC

•••••

The MIL will turn off after three consecutive driving
cycles in which the diagnostic runs without a fault.

•••••

A history DTC will clear after 40 consecutive warm-
up cycles without a fault.

•••••

The DTC(s) can be cleared by using the scan tool.

Diagnostic Aids

An intermittent problem may be caused by a poor con-
nection, rubbed-through wire insulation, or a wire that is
broken inside the insulation.

Any circuitry, should be thoroughly checked for the fol-
lowing conditions:

•••••

Backed-out terminals

•••••

Improper mating

•••••

Broken locks

•••••

Improperly formed

•••••

Damaged terminals

•••••

Poor terminal-to-wire connection

•••••

Physical damage to the wiring harness

Test Description

Number(s) below refer to the step(s) number on the
Diagnostic Table.

1. Euro On-Board Diagnostic (EOBD) System Check

prompts the technician to complete some basic
checks and store the freeze frame and failure
records data on the scan tool if applicable. This
creates an electronic copy of the data taken when
the malfunction occurred. The information is then
stored on the scan tool for later reference.

9. The replacement ECM must be reprogrammed. Re-

fer to the latest Techline procedure for ECM repro-
gramming.

Perform the Euro On-Board Diagnostic (EOBD) System
Check.
Is the system check complete?

1. Turn the ignition ON, with the engine OFF.
2. Install a scan tool.
3. Press the clutch pedal.
Does the scan tool indicate that the CLUTCH SWITCH
is changed OFF to ON?
1. Turn the ignition OFF.
2. Disconnect the Engine Control Module (ECM)

connector.

3. Turn the ignition ON.
4. Using a Digital Voltmeter (DVM), measure the clutch

switch connector terminal 2 and ECM connector
terminal 43.

Does the resistance near the specifies value?

With a test light connected to battery postive, probe the
clutch switch connector terminal 1.
Does the test light illuminate?
1. Turn the ignition OFF.
2. Replace the clutch switch.
Is the repair complete?
Check the clutch switch connector terminal 1 to ground
for open or short and repair if necessary.
Is the repair complete?
Check for open or short in the wire between clutch
switch connector terminal 2 and ECM connector
terminal 43 and repair if necessary.
Is the repair complete?
1. Turn the ignition OFF.
2. Replace the ECM.
Is the repair complete?
1. If disconnected, reconnect the clutch switch

electrical connector.

2. Using the scan tool, clear the Diagnostic Trouble

Codes (DTCs)

3. Start the engine and idle at normal operating

temperature.

4. Operate the vehicle within the conditions for setting

the DTC as specified in the supporting text.

Does the scan tool indicate that this diagnostic has run
and passed?
Check if any additional DTCs are set.
Are any DTCs displayed that have not been diagnosed?
