To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.

(1)

Connect scan tool MB991958. Refer to "How to connect the
Scan Tool (M.U.T.-III) P.54Ad-5."

(2)

Turn the ignition switch to the "ON" position.

(3)

Erase the DTC.

(4)

Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.

(5)

Check if DTC is set.

(6)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the DTC set?

YES:

Replace with the coded ETACS-ECU.

NO:

The diagnosis is complete.

DTC B210A: +B power supply (low input)
DTC B210B: +B power supply (high input)

TROUBLE JUDGMENT
The ETACS-ECU sets DTC B210A if the power supply
fuse voltage decreases to the specified value or less,
and sets DTC B210B if the power supply fuse voltage
increases to the specified value or more. However,

when the status returns to normal, the ETACS-ECU
automatically erases DTCs B210A and B210B.

TECHNICAL DESCRIPTION (COMMENT)
The power supply fuse or the ETACS-ECU may have
a problem.

TROUBLESHOOTING HINTS

｠

The power supply fuse may be defective.

｠

The ETACS-ECU may be defective.

｠

The battery may be defective.

｠

The alternator may be defective.

｠

The wiring harness or connectors may have loose,
corroded, or damaged terminals, or terminals
pushed back in the connector

DIAGNOSIS

STEP 1. Power supply fuse check.

Q:Is the fuse in good condition?

YES:

Go to Step 2.

NO:

Replace the power supply fuse, and then go to Step

2.

STEP 2. Check ETACS-ECU connector C-307 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.

Q:Is ETACS-ECU connector C-307 in good condition?

YES:

Go to Step 3.

NO:

Repair or replace the component(s). Refer to GROUP

00E, Harness Connector Inspection P.00E-2.

STEP 3. Check the battery power supply circuit to the
ETACS-ECU. Measure the voltage at ETACS-ECU connector
C-307.

(1)

Disconnect ETACS-ECU connector C-307 and measure the
voltage available at the wiring harness side of the connector.

ZC6022230000

Connector C-307
(Harness side)

(2)

Measure the voltage between terminal 2 and ground.

｠

The voltage should measure approximately 12 volts
(battery positive voltage).

Q:Is the measured voltage approximately 12 volts (battery

positive voltage)?

YES:

Go to Step 5.

NO:

Go to Step 4.

STEP 4. Check the wiring harness between ETACS-ECU
connector C-307 (terminal 2) and the fusible link (36).

Q:Is the wiring harness between ETACS-ECU connector

C-307 (terminal 2) and the fusible link (36) in good

condition?

YES:

No action is necessary and testing is complete.

NO:

The wiring harness may be damaged or the connector

(s) may have loose, corroded or damaged terminals, or
terminals pushed back in the connector. Repair the wiring
harness as necessary.

STEP 5. Using scan tool MB991958, check data list.
Check the power supply fuse voltage.
