Diagnostic Test

1.

TEST FOR INTERMITTENT CONDITION

With the scan tool, record and erase DTC’s

Press the Memory Set Switch several times in all positions.

Cycle the ignition from on to off three times.

Turn the ignition on.

With the scan tool, read DTC’s.

Does the scan tool display MEMORY SWITCH INPUT CIRCUIT STUCK?

Yes

>> Go To 2

No

>> The conditions that caused this code to set are not present at this time. Using the wiring diagram/sche-

matic as a guide, inspect the wiring and connectors.

Perform BODY VERIFICATION TEST - VER 1. (Refer to BODY VERIFICATION TEST - VER 1).

2.

MEMORY SELECTOR SWITCH SHORTED TO GROUND

With the scan tool, erase DTC’s.

Disconnect the Memory Set Switch connector.

Turn the ignition on.

With the scan tool, read DTC’s.

Does the scan tool display MEMORY SWITCH INPUT CIRCUIT
STUCK?

No

>> Replace the Memory Set Switch.

Perform BODY VERIFICATION TEST - VER 1. (Refer to
BODY VERIFICATION TEST - VER 1).

Yes

>> Go to 3

3.

(P200) MEMORY SELECT SWITCH MUX CIRCUIT SHORT TO THE GROUND

Disconnect the Driver Door Module C3 connector.

Measure the resistance between ground and the (P200) Memory Select
Switch Mux circuit.

Is the resistance below 10000.0 ohms?

Yes

>> Repair the Memory Select Switch Mux wire for a short to

ground.

Perform the BODY VERIFICATION TEST - VER 1. (Refer
to BODY VERIFICATION TEST - VER 1).

No

>> Go to 4

4.

(P200) MEMORY SELECT SWITCH MUX CIRCUIT SHORT TO THE (G920) MEMORY SELECT SWITCH
RETURN CIRCUIT

Measure the resistance between the (P200) Memory Select Switch Mux
circuit and the (G920) Memory Select Switch Return circuit in the Driver
Door Module C3 connector.

Is the resistance below 10000.0 ohms?

Yes

>> Repair the (P200) Memory Select Switch Mux circuit for a

short to the (G920) Memory Select Switch return circuit.

Perform BODY VERIFICATION TEST - VER 1. (Refer to
BODY VERIFICATION TEST - VER 1).

No

>> Replace the Driver Door Module.

Perform BODY VERIFICATION TEST - VER 1. (Refer to
BODY VERIFICATION TEST - VER 1).

B210D-BATTERY VOLTAGE LOW

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
Engine running.

•

Set Condition:
This code is set immediately after the Door Module detects voltage under 11.3 volts on the (A913) Fused B(+)
circuit.

Possible Causes

CHARGING SYSTEM VOLTAGE LOW

(A913) FUSED B(+) CIRCUIT

DRIVER/PASSENGER DOOR MODULE

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

Diagnostic Test

1.

CHECK PCM FOR CHARGING SYSTEM DTC

With the scan tool, read Powertrain Control Module DTC’s.

Are there any Charging System DTC’s set in the Powertrain Control Module?

Yes

>> (Refer to 8 - ELECTRICAL/CHARGING - DIAGNOSIS AND TESTING) for Charging System diagnostic

procedures.

No

>> Go To 2

Perform BODY VERIFICATION TEST – VER 1. (Refer to BODY VERIFICATION TEST - VER 1).

2.

VERIFY THAT DTC B210D-BATTERY VOLTAGE LOW IS ACTIVE

With the scan tool, record and erase DTC’s

Turn the ignition switch to the OFF position then start the engine and let run for one minute.

With the scan tool, read DTC’s.

Does the DTC B210D-BATTERY VOLTAGE LOW reset?

Yes

>> Go To 3

No

>> The conditions that caused this code to set are not present at this time. Using the wiring diagram/sche-

matic as a guide, inspect the wiring and connectors.

Perform BODY VERIFICATION TEST – VER 1. (Refer to BODY VERIFICATION TEST - VER 1).

3.

CHECK THE VOLTAGE ON THE (A913) FUSED B(+) CIRCUIT

Disconnect the appropriate Door Module C4 connector.

NOTE: Check connectors - Clean and repair as necessary.
Start the engine and let idle.

Measure the voltage on the (A913) Fused B(+) circuit at the Door Mod-
ule C4 connector and compare to voltage at the vehicle battery.

Is the voltage at the Door Module C4 connector the same as
measured at the battery?

Yes

>> Replace the Driver/Passenger Door Module in accordance

with the service information.

Perform BODY VERIFICATION TEST – VER 1. (Refer to
BODY VERIFICATION TEST - VER 1).

No

>> Repair the (A913) Fused B(+) circuit as necessary.

Perform BODY VERIFICATION TEST – VER 1. (Refer to
BODY VERIFICATION TEST - VER 1).
